???The display and keys can be illuminated for night-time use.

The chartplotter includes a 64nm world map that can be used for route planning. Detailed navigation information is displayed when a Navionics?? Nav-Chart card is installed.

Your vessel???s position is shown as a boat symbol pointing in your current direction.

At the top of the chartplotter screen a status bar displays chart scale, cursor position plus range and bearing, the vessel???s position, Speed Over Ground (SOG) and Course Over Ground (COG).

Waypoints you have placed are displayed and the current route is shown. Data can be viewed for current route or chart object.

The chartplotter screen can also show additional information, depending on your currently selected options, set up selections and data available from other equipment.

An example chart display in its default configuration, with a chart card installed, is shown in Section 1.3, Operating controls.

Several functions are available to control the display as follows:

???Zoom in/out

???Pan the Display.

???Centre the Chart around the Vessel.

Operation of these functions is described in Chapter 2.

Display options

Display options are selected in System Set Up and Chart Set Up as described in

Chapter 4.

1.3 Operating controls

The chartplotter is operated by means of the following controls:

???A trackpad providing up, down, left, right and diagonal control of an on- screen cursor.

???Six dedicated push-button (labelled) keys.

???Pop-up menus, displayed on-screen, from which you select options.

???Database lists, displayed on-screen, which enable you to edit items.

Note: The cursor is the cross-hair symbol (+) visible on the display. You move the cursor with the trackpad and use it to select a position or item on the chart.

The controls are shown in the following illustration. They are back-lit for night- time use.

The following paragraphs describe the controls and on-screen facilities.

The cursor is context-sensitive. Some items on the screen, such as waypoints and chart objects have information associated with them. When you place the cursor over such objects, the information is displayed in the status bar. In addition, a function bar is displayed for certain items. For example, when you place the cursor over a waypoint, the waypoint data is displayed in the status bar and the waypoint options function is displayed.

Dedicated keys

These keys have fixed functions. Some keys can be used in two ways:

???Press: Press the key momentarily and then release it. This method is used for most key operations.

???Press and hold: Press the key and hold it down for the period of time stated (eg. 3 seconds), then release it.

When you press a dedicated key, one of the following occurs:

1.The associated operation is actioned, eg. change chart scale (RANGE key).

2.A pop-up menu is displayed, providing further options.

3.A set of functions is displayed.

As you press a key, a single audio beep confirms the key action. If the key-press is not valid for the current screen or mode, three rapid beeps sound to indicate that no response is available. If required, you can turn the key beeps off as part of your set up procedure (see Chapter 4).

Function bar

The function bar at the bottom of the screen contains a number of functions which change according to the current operation. The functions are grouped into related sets and subsets providing access to the various functions. The primary function bar is displayed when you press the ENTER key.

The currently selected function is highlighted by means of a grey background.

When you invoke a function, one of the following occurs:

1.The associated operation is actioned, eg. GOTO WAYPOINT.

2.A sub-set of functions is displayed.

3.A pop-up menu is displayed, providing further options.

4.The appropriate database list (route or waypoint) is displayed.

As with dedicated keys, when you invoke the action, a single audio beep confirms the action. If the selection is not valid for the current screen or mode, three rapid beeps indicate invalid action. If required, you can turn the key beeps off as part of your set up procedure (see Chapter 4).

Pop-up menus

Pop-up menus usually provide various options. When a pop-up menu is on-screen, a set of associated functions is also displayed.

Use the trackpad to select an option from the menu, then use the appropriate function to set the option, eg. you can specify the radius of the waypoint arrival alarm and you can set selected navigation data on/off.

Database lists

The waypoints and routes that you create on the chartplotter are stored in database lists. You can view these lists and select items for editing.

As with pop-up menus, when a database list is on-screen, a set of associated soft keys is also displayed; use the trackpad to select an item from the list, then use the appropriate function to edit the item, eg. you can erase a waypoint or a route.

Chapter 2: Getting started

2.1 Introduction

This chapter provides information, instructions and a simple exercise to allow you to practice using the RayChart 420 Chartplotter. It is intended to help you become familiar with the controls before you start using the chartplotter for routine navigation.

Note: There is often more than one method of performing a particular task. Normal operating procedures are detailed in Chapter 3. When you become familiar with the system you can adapt these procedures to suit your method of operation.

Conventions used

Throughout this handbook, the dedicated (labelled) keys are shown in bold capitals; for example, ENTER. The functions and options are shown in normal capitals, eg. LIGHT.

Operating procedures, which may consist of a single key-press, or a sequence of numbered steps, are indicated by a ??symbol in the margin.

When textual data is displayed on screen, any unavailable data is shown as dashes, one per character.

Where procedures refer to Select, this implies using the trackpad to highlight a function, then pressing the ENTER key to action that function.

Simulator

The Chartplotter display unit includes a simulator mode, which allows you to practice operating your chartplotter without data from a GPS system. You will need to use the set up options to switch the display to simulator mode, as described in Section 2.2, Switching on/off. You can use it in either of two ways:

???Before the chartplotter has been installed on your vessel. In this case, you only need to connect the Chartplotter display unit to a 12V dc power supply, fused at 1A, connecting the red core from the power lead to positive (+) and the black core to negative (-); see Chapter 5 for full details.

???After the chartplotter has been installed on your vessel, but while in the marina or at anchor.

2.2 Switching on/off

This section explains how to switch the chartplotter on and off.

??To turn the chartplotter display unit on, press the POWER key. The keys light up, the display unit beeps and the RayChart logo is displayed, followed by the following warning:

WARNING

THE ELECTRONIC CHART IS AN AID TO

NAVIGATION DESIGNED TO FACILITATE

THE USE OF AUTHORISED GOVERNMENT

CHARTS, NOT TO REPLACE THEM. ONLY

OFFICIAL GOVERNMENT CHARTS AND

NOTICES TO MARINERS CONTAIN ALL

INFORMATION NEEDED FOR THE SAFETY

OF NAVIGATION AND, AS ALWAYS, THE

CAPTAIN IS RESPONSIBLE FOR THEIR

PROPER USE.

Press ???ENTER??? to continue.

When you have read and understood the warning, press the ENTER key. The chart is displayed.

If this is the first time that the chartplotter has been switched on, and no chart card is installed, the display shows the small-scale world map at Lat 0??/Lon 0??. Otherwise, the display shows the selected chart area and any data that were displayed when the display unit was last used.

??To turn the display unit off, press and hold the POWER key for at least 3 sec- onds. A countdown timer is displayed; when it reaches zero the display and key back-lights extinguish.

Changing the lighting and contrast

You can change the level of backlighting and contrast for the screen. The key backlighting remains on to enable the keys to be seen at all times.

??To change the lighting and contrast:

1. Press the POWER key to display the lighting controls:

The last-used control is highlighted in inverse video.

2.Press the trackpad left/right to select the LIGHTS function.

3.Press the trackpad top/bottom to increase or decrease the lighting to one of four levels. You can press and hold the trackpad to change the setting more rapidly. The lighting level is adjusted as you change the setting.

4.Press the trackpad right to select the contrast control. There are 16 contrast levels. Adjust the setting in the same way as for lighting to select the best level.

5.Press CLEAR to return to the chart screen, with the new lighting and contrast levels retained.

When the display unit is switched on, screen lighting is restored to ON if it was ON previously. Whilst the unit is switched on, the chosen lighting level is retained until you reset it. The new contrast level is retained until you reset it, even after power-off, unless you set the control very low or very high; in this case, the contrast will be restored on power-up as follows:

2.3 Chart simulator

When simulator mode is started, your initial simulated position is wherever the cursor was last positioned. To practice using the chartplotter in a particular chart area, use the trackpad to pan to that area, then switch simulator ON.

Note: If real position data is available (via GPS or dGPS) and the simulator is active, simulated data takes precedence. On power-up the simulator defaults to its previous setting on power-down. Care should be taken to determine

desired mode on power-up. Simulated data should never be used for navigational purposes.

??To view a chart image using simulated data:

1. Press the PAGE key to display the SET UP function bar:

2.Press trackpad left/right to highlight SYSTEM SET UP and press ENTER to display the System Set Up menu.

3.Use trackpad up/down to highlight the SIMULATOR option .

4.Use trackpad left/right to select ON.

5.If necessary, use trackpad up/down to highlight, in turn, the SIMULATED SOG and COG options and trackpad left/right to set as required . These set Speed in 1Kt intervals and Course in 1?? intervals, respectively.

6.Press CLEAR twice to return to the chart screen.

2.4Controlling the display

This section describes how to:

???Change the display mode.

???Move around the chart by panning the display, changing the chart centre and changing the chart scale.

Selecting the display mode

Use the PAGE key to select the display mode. Select the following modes by repeat presses of the PAGE key as listed below and shown in the following illustration:

???Set Up functions (see Chapter 4)

???Course Deviation Indicator (CDI)

???Bearing & Distance Indication (BDI)

???Waypoint data

???Navigation data

???Time/Date data

???Return to Set Up functions

Note: Press GOTO to return to normal Chart display at any time.

Moving around the chart

You will normally operate the chartplotter with the chart showing your vessel???s current location.

In the default North-Up orientation, the vessel moves in relation to the screen. You will need to reposition the chart if your vessel moves out of the area currently displayed, or if you wish to examine or place waypoints in another area.

Alternatively, you can home the cursor onto the vessel using the FIND SHIP function. ???Homing??? locks the vessel to the cursor and updates the display such that the chart is re-drawn so as to ensure that the vessel is always on screen, see

Using FIND SHIP below.

There are three ways in which you can reposition the chart:

???Use the trackpad to move the cursor to the edge of the chart; the chart pans across. This method is useful if the area you wish to see is just off screen.

???Automatically re-centre the vessel using the FIND SHIP function.

???Change the chart scale using the RANGE key to zoom out and in to a new area. This method is useful if the area you wish to see is some distance away.

Using FIND SHIP

FIND SHIP is used to re-draw the chart with the vessel normally at its centre and the cursor homed on the vessel.

??To centre the vessel:

1. From chart mode, press ENTER; the primary function bar is displayed:

Select FIND SHIP; the following actions are performed:

???The chart is re-drawn with the vessel???s position in the centre.

???The cursor is homed onto the vessel position and moves with it.

???When the vessel moves near the edge of the chart window, the chart is redrawn with the vessel at the centre and the cursor homed on the vessel.

???Whilst homed, the status bar indicates vessel position, SOG and COG.

???If Screen Amplifier is enabled, the vessel is positioned so as to increase screen forward visibility, see Chapter 4, Setting Up the Chartplotter.

??To release the cursor from homed mode press the trackpad to move the cursor away from the vessel???s current position. The status bar shows the cursor position, range and bearing.

Changing the chart scale

The RANGE key allows you to change the chart scale so that you can see a smaller or larger area on the screen.

Plotter mode is available to allow you to zoom into a smaller area, even when no chart data is available for that scale. To enable plotter mode, see Chapter 4, Setting Up the Chartplotter.

You can change the chart scale for two purposes:

???To see either more detail (of a smaller area) or a larger area (in less detail) .

???To move the display to another area of the chart, by zooming out to a small scale chart, then zooming in on another position.

Each time you press the RANGE key, the chart scale changes to the next available setting. The Status Bar at the top of the screen indicates the distance, from top to bottom of the display, in nautical miles.

Vertical distance

displayed on chartIncreases the chart range

??For rapid scale change, press and hold the required arrow on the RANGE key.

The distance indicator at the left-hand end of the status bar is updated whenever you change the chart scale.

??To zoom in to a larger-scale (more detailed) chart:

1.Use the trackpad to position the cursor in the area you wish to see in more detail and press the bottom of the RANGE key to zoom into the area.

The section of the chart around the cursor is enlarged to fill the screen with a larger-scale chart showing more detail. The cursor is now positioned in the centre of the screen.

The distance indicated at the top left of the screen is updated.

3.If further chart enlargement is available using the current chart card you can press the bottom of the RANGE key to zoom in again, repositioning the cursor first if required.

An area of further chart detail is indicated by a box around the area as shown in the following illustration.

Removing a Nav-Chart card

CAUTION:

DO NOT use a metallic instrument, eg. a screwdriver or pliers, to aid removal as doing so can cause irreparable damage.

??To remove a Nav-Chart card:

1.Pull out the cartridge cover at the right hand side of the unit.

2.Grip the card firmly and pull to remove it from its slot.

3.To prevent the ingress of water , replace the cartridge cover.

Note: If difficulty is experienced in removing the card, a short length of cord can be secured between the two circular holes in the card to ease its removal, making sure that fitting of the cartridge cover is not impeded.

Displaying the chart data

The new chart data will be displayed when you move the cursor into an area covered by the new chart or, if it is already in the area, change the range scale.

The boundary of each chart digitized in the current card is defined by a box or rectangle. (You can switch off the chart boundaries display if you wish, as part of the chartplotter set up described in Chapter 4).

??To zoom in:

1.Use the trackpad to move the cursor inside one of the chart boxes.

2.Press the lower part of the RANGE key.

That area is expanded to show more detail. The smaller the chart box is on the screen, the greater the detail that is available when you zoom in. Unless you have activated Plotter Mode (see Chapter 4, Chart Set Up), you cannot zoom in further than the most detailed chart and you cannot zoom out further than the world map.

Displaying chart information

Nav-Chart cards include a number of displayed objects for which data is available, eg. lights, buoys or ports. Placing the cursor over an object displays its associated data in a pop-up box.

At large chart scales, placing the cursor over a port symbol enables detailed information to be displayed. Port information is indicated by the symbol . The port facilities are listed in the object information pop-up and, where available, details for each facility can be displayed.

In some areas the chart shows symbols for individual facilities. These facilities and symbols are dependent upon the particular area Nav-Chart card used.

??To obtain port services information:

1.Place the cursor over the port symbol for which you require information. The PORT SERVICES function, together with help text, is displayed:

D4707_1

2.To view further details, press ENTER. The details available are listed on- screen in an object information pop-up:

Chapter 3: Operation

3.1 Introduction

This chapter explains how to use the chart functions to navigate with your RayChart 420. It covers the following topics:

???Controlling waypoints; placing, moving, editing and deleting waypoints

???Working with routes; creating a new route, managing routes using the route database and editing routes

???Going to waypoints and following routes

???Changing display modes

???Transferring waypoints and routes

???Using tracks; track set up, showing current track and converting a track to a route (SmartRoute)

???Man Overboard

???Alarms

Safety

The RayChart 420 makes it very easy to mark a waypoint and travel towards it. However, you should always check first that the route is safe. If you are using the chartplotter in combination with an autopilot connected via NMEA, the autopilot will normally prompt for confirmation before it steers the vessel towards the waypoint.

If you have entered your route using a small-scale chart, zoom in to a larger scale to check for hazards, such as small shoals, that may not be shown on the smaller scale charts.

Note: Until you are familiar with interpreting the chart display, you should take every opportunity to compare the displayed objects with visual targets, such as buoys and coastal structures. You should practice harbour and coastal navigation during daylight and in clear weather conditions.

The equipment should not be used as a substitute for good navigational practice.

3.2 Working with waypoints

Introduction

The RayChart 420 enables you to place up to 500 waypoints. A waypoint is a position entered on a chart as a reference or destination point. All waypoints placed on the chartplotter are stored in a waypoint database list which includes symbol, position, bearing, range, date and time.

All waypoints in the database are displayed on the screen, unless you set SHOW WAYPOINTS to OFF in the Chart Set Up menu, as described in Chapter 4. You can select a waypoint, either on-screen or from the list, for editing.

The waypoint is usually placed at the cursor position and can be part of a route; you can also place a waypoint at the vessel???s current position. You can place waypoints before you install the chartplotter on your vessel.

When you place a new waypoint, it is displayed using either the default symbol of a cross or an alternative symbol available from the Chart Set Up menu, as described in Chapter 4. The waypoint is added to the waypoint list and named with the next available number. You can use the edit functions to change the symbol and name. When the cursor is positioned over a waypoint, the waypoint bearing and range are displayed.

You can also transfer waypoints between the chartplotter and other NMEA connected instruments using the Waypoint Transfer functions.

This section explains how to perform the following tasks using the on-screen cursor and the waypoint list:

???Placing a Waypoint

???Selecting a Waypoint

???Displaying Waypoint data

???Editing a Waypoint (symbol, name & position)

???Erasing a Waypoint

???Moving a Waypoint

The cursor now controls the new waypoint which is connected to the existing waypoints on either side with a dotted line. The subsequent waypoint(s) are renumbered accordingly.

4.Using the trackpad, place the new waypoint and press ENTER.

5.Move the new waypoint to the required position and press ENTER to place it and return to normal cursor operation or CLEAR to cancel the operation.

6. Press CLEAR again to remove the function bar and route leg data.

The new waypoint is temporarily added to the waypoint list and named with the first available waypoint number. The waypoints in the current route are re- numbered to identify the new positions.

??To remove a waypoint from the route using the cursor:

1.Place the cursor over the waypoint; see Selecting a waypoint in Section 3.2.. The Waypoint functions are displayed.

2.Select REMOVE WAYPOINT; the waypoint is removed from the route.

3.4Following routes and going to target points

The GOTO key accesses the functions to follow a route or go to a waypoint, port or current cursor position. When you select the target destination, the chartplotter calculates bearing, distance and cross track error; this information can be displayed or passed to an autopilot via NMEA. You can also restart the Cross Track Error (XTE) from the actual vessel position to set XTE to zero at that point.

When the chartplotter is following a route, the target destination is indicated by a square around the waypoint (or cursor marker) and a dotted line shows the intended track, from your start point or previous waypoint, to the target waypoint.

This section explains how to perform the following tasks:

???Follow a route.

???Reverse a route.

???Target Point Arrival.

???Altering the route, including joining at a selected waypoint, advancing waypoints and restarting XTE.

???Go to an individual point, either an existing waypoint or the cursor.

???Go to the nearest or a selected port.

???Stop and Restart Follow/Goto.

An alarm is triggered when you approach a waypoint. Chapter 4 describes how to set the alarm.

??To access the follow and goto functions:

1. Press the GOTO key to display the first level GOTO functions:

The current route is reversed on the screen and the waypoints are renumbered.

??To follow the reversed route:

4.Press the GOTO key. The Goto/Follow functions are displayed.

5.Press FOLLOW ROUTE.

Your vessel???s current position becomes the origin and the first waypoint in the reversed route becomes the target waypoint. The function bar is removed.

Target point arrival

You can set up target alarms (see Chapter 4) to alert you when the vessel is approaching the target point. The arrival alarm is defined as a circle (not visible on the screen), with a specified radius around the target.

The alarm is triggered when either of the following conditions is met:

???The distance to the target point is less than that specified for the Arrival alarm.

???Your vessel reaches the closest point of approach to the target (ie. it crosses a line passing through the waypoint and perpendicular to the track).

??To cancel the Arrival alarm and go towards the next waypoint in the route, press any key.

The target becomes the origin, the next waypoint becomes the target point and the two are connected by a dotted line indicating the current leg.

If the target waypoint was the subject of a GoTo, or was the last waypoint in a route, the pop-up alarm is cleared and any temporary waypoint is removed.

Alter a route

You can use the functions to follow a route from a selected waypoint (Join a route) or, if already following, you can advance to the next waypoint. You can also restart the XTE, setting the current vessel position as the new origin.

In addition, you can move a selected waypoint as described in section 3.2, or remove a waypoint from the route as described in section 3.3.

Join a route

??To start following the current route from a selected waypoint:

1.Move the cursor over a route waypoint until the ROUTE OPTIONS function is displayed:

2. Press ENTER and select FOLLOW FROM HERE.

D4687_1

Your vessel follows the route, using the selected waypoint as the target.

3.To return to chart mode, move the cursor away from the waypoint or press

CLEAR.

Advance to a waypoint

When following a route you can advance to the next waypoint, even if you have not reached the current target waypoint.

??To advance to a waypoint:

1. Press the GOTO key to display the Goto/Follow functions:

D4688_1

2.Select WAYPOINT ADVANCE. The current leg of the route is abandoned and the next waypoint becomes the target. The display is updated to show the new route leg.

Restart Cross Track Error (XTE)

Reset XTE is useful if you find yourself off track and want to go straight to your target, rather than get back onto the original track.

Whilst following a route, or going to a target point, you can restart the XTE. This sets the XTE to zero and moves the origin to the vessel???s actual position.

??To restart XTE:

1.Press the GOTO key.

If following a route, the following functions are displayed:

D4688_1

If a GOTO is already in progress, the following functions are displayed:

D4689_1

2.Select RESTART XTE. The dotted line between the previous and next waypoints is redrawn from the vessel???s current position to the next waypoint and the XTE is reset to zero

Going to an individual target

Rather than following a route, you can go directly to a selected target. This can be an existing waypoint, a port or the current cursor position.

Go to a waypoint

??To navigate directly to an existing waypoint:

1.From the normal chart display either:

a)Use the trackpad to position the cursor over the required waypoint until the waypoint options function is displayed:

...then press ENTER to display the waypoint functions:

or b) press the GOTO key to display the waypoint options and select GOTO WAYPOINT; the waypoint list appears. Use the cursor to select the required waypoint:

D4690_1

Alternatively, you can select the waypoint from the waypoint list as described in section 3.2

2.Select GOTO WAYPOINT.

A dotted line is drawn between the vessel???s current position and the selected waypoint and navigation to the selected waypoint begins.

Go to cursor

Note: If navigation is currently in progress or if the cursor is homed (Find Ship) it is not possible to go to cursor.

??To navigate directly to the current cursor position:

1.Press the GOTO key and select GOTO CURSOR. The GOTO CURSOR function now has help text appended to it:

D4691_1

2.Use the trackpad to position the cursor as required.

3.Press ENTER to start the GoTo, or CLEAR to cancel the operation. A temporary waypoint is placed at the cursor position and navigation proceeds towards it. The waypoint is shown as a square with a dot in the centre and is connected to the vessel???s starting position with a dotted line.

On arrival, the arrival alarm is sounded and the arrival pop-up box is displayed.

Note: The temporary waypoint is not added to the waypoint list; when the GoTo is complete, or is stopped, the temporary waypoint is erased.

Go to a port

You can navigate directly to the nearest port or to a selected port or facility.

??To navigate directly to selected port:

1.Press the GOTO key and select GOTO PORT to display the Port List.

2.Use trackpad up/down to select the required port and press ENTER to start the GoTo, or CLEAR to cancel the operation.

A dotted line is drawn between the current vessel position and the target waypoint which is placed at the port. The line remains fixed on the screen as the vessel moves.

Bearing, Range and Cross Track Error are calculated for the target waypoint in the same manner as for GOTO CURSOR.

On arrival, the arrival alarm is sounded and the arrival pop-up box is displayed.

??To navigate directly to the nearest port or facility:

1.Press the GOTO key and select GOTO NEAREST to display the list.

2.Use trackpad up/down to select the required facility and press ENTER to start the GoTo, or CLEAR to cancel the operation.

The list shows the eight nearest places where the selected facility exists, in order of distance. The bearing and range (in selected units) for each one is shown.

3.Use trackpad up/down to select the required destination and press ENTER to start the GoTo, or CLEAR to cancel the operation.

The operation is conducted in the same manner as for GO TO PORT above.

Stop follow or stop goto

??To stop following the route or target point:

1.Either press the GOTO key or move the cursor over the target waypoint.

2.Select the STOP GOTO or STOP FOLLOW function respectively:

D4688_1

The dotted line from your vessel to the target waypoint disappears.

3.5 Changing the display mode

Use the PAGE key to select the required display mode. Repeat presses of the PAGE key provide the following display modes:

???Set Up functions (see Chapter 4)

???Course Deviation Indicator (CDI)

???Bearing & Distance Indication (BDI)

???Waypoint data

???Navigation data

???Time/Date data

???Return to Set Up functions

Note: Press GOTO in any display mode to return to normal Chart display.

??To change the display mode:

1.Press the PAGE key to show the SET UP functions with SYSTEM SET UP highlighted:

2. Repeat Step 1 to cycle through each of the available display modes.

Note: The Set Up Function Bar remains displayed in each display mode.

To remove the Set Up Function Bar, press CLEAR.

CDI display

The CDI display shows Cross Track Error (XTE) and distance to waypoint presented in a ???runway??? format:

D4700_1

The ???runway??? represents a 0.3nm width with the vessel symbol shown at the bottom. Bearing to Waypoint, Distance to Waypoint, Time to Go (TTG), Course Over Ground (COG) and Speed Over Ground (SOG) are also shown. Time to Go is calculated on the basis of distance to destination and Speed Over Ground (SOG) towards the destination.

At waypoint ranges greater than 4nm, the symbol remains at the top of the screen. As the waypoint range falls below 4nm, the symbol moves down the centre line.

The chequered pattern moves down the screen to simulate movement when SOG is greater than 2 knots.

The steering instruction is STEER STARBOARD if the XTE is 0.01nm or more to port, STEER PORT if the XTE is 0.01nm or more to starboard or ON COURSE if the XTE is less than 0.01 on either side. If no GOTO or follow is in progress, the steering instruction is NO TARGET.

The graphical XTE indication places arrows either side of the steering instruction and pointing towards it, dependent on the value of XTE.

The first arrow is shown when the XTE reaches 0.01nm, the second at .05nm and subsequently at 0.1nm intervals .

BDI display

The BDI display shows deviation from the bearing to waypoint and distance to waypoint. Cross track Error, Bearing to Waypoint, Distance to Waypoint, Time to Go, COG and SOG are also shown. Time to Go is calculated on the basis of distance to destination and velocity made good towards destination.

D4701_1

The line to the waypoint symbol is shown at an angle equal to the difference between the COG and the Bearing to Waypoint. The waypoint symbol is the symbol of the target waypoint as seen on the chart.

The range scale automatically scales for distance. The ranges shown are 4nm, 20nm, 40nm, 100nm, 200nm, 400nm, 1000nm, 2000nm, 4000nm. In each case the range scale has graduations at ??, ?? and ?? of the current scale.

The steering instruction is STEER STARBOARD if the waypoint line is 1?? or more to port, STEER PORT if the waypoint line is 1?? or more to starboard or ON COURSE if the waypoint line is dead ahead. If no GOTO or follow is in progress, the steering instruction is NO TARGET, no steering arrows are shown, but the rhumb line indicator is shown.

The graphical XTE indication will place arrows either side of the steering instruction and pointing towards it dependent on the difference between COG and bearing to Waypoint. The first arrow is shown when the difference reaches 5?? and thereafter at 5?? intervals.

Waypoint data

The Waypoint Data display comprises text data occupying the whole screen :

ROUTE

ROUTE 01

WAYPOINT

WPT 001

BRG 234?? T

RNG 12.4 nm

STEER STARBOARD

D4702_1

If a route is not selected, the ROUTE field displays NO ROUTE.

The WAYPOINT field shows the name of the waypoint. If the waypoint is part of a route then the title field includes the waypoint index in the route. If there is no target waypoint the text indicates NO WAYPOINT and all waypoint data is shown as dashes, one per character. If a route is being followed and the waypoint is not named, the text shows the waypoint number within the route (as displayed on screen). If a GOTO Cursor or Port is in progress, the text indicates GOTO CURSOR or GOTO ???Port Name???.

BRG, RNG and XTE data relate to the target waypoint.

The Time refers to local time and is set in the System Set Up menu, Chapter 4.

The Time To Go (TTG) and Estimated Time of Arrival (ETA) data relate to the target waypoint (not the whole route) and are based on the Speed Over Ground (SOG) towards the target. If the VMG is negative, or data is not available, these fields are replaced by dashes, one per character.

The steering instruction is STEER STARBOARD if the XTE is 0.01nm or more to port, STEER PORT if the XTE is 0.01nm or more to starboard or ON COURSE if XTE is less than 0.01 on either side.

If no GOTO or follow is in progress, the steering instruction is NO TARGET, no steering arrows are shown, but the rhumb line indicator is shown.

The graphical XTE indication places arrows either side of the rhumb line indicator and pointing towards it, dependent on the value of XTE. The first arrow is shown when the XTE reaches 0.01nm, the second at .05nm and subsequently at 0.1nm intervals .

Note: The steering instruction and graphical XTE indication are repeated on all text-only displays.

Navigation data

The Navigation Data display comprises text data occupying the whole screen:

POSITION

50??45 .000 N

001??06 .000 W (c)

COG 230?? T

SOG 6.8 Kts

STEER STARBOARD

D4703_1

Textual data provides Position, SOG, COG, Bearing and Range to waypoint, Time, Fix status and the XTE indicator. Any unavailable data is replaced by dashes, one per character. When there is no GPS fix but there is a value for the last fix, this is shown instead; POSITION is replaced with LAST POSITION.

The (c) indicator only appears when the position has been user calibrated.

The Fix indicator shows the GPS Fix status and indicates either FIX OK or NO FIX. In the case of a differential fix, D-FIX is displayed.

Note: Graphical XTE indicator is as per Waypoint data screen, see above.

Time/Date Data

The Time/Date display comprises text data occupying the whole screen:

TIME 12:34

DATE 26/01/99

STEER STARBOARD

D4704-1

Textual data provides Sunrise and Sunset time, Current Time/ Date, Waypoint and Route arrival times plus the XTE indicator.

Sunrise and Sunset times are for the selected day and at the selected position. The TODAY indicator emphasises that the sunrise and sunset times relate to the current day. If you select another day, the TODAY text is replaced with ON XX/XX/XX where XX/XX/XX is the selected date in the current format.

When the Time/Date screen is first opened, the data relates to the current day, unless there is no date information available. In this case the last date is used. The vessel???s current position is used unless there is no GPS fix in which case the cursor position is used and shown as a USER SELECTED position.

The position data can be either as selected by you, in which case the text relating to the position is USER SELECTED, or the current position in which case the text is VESSEL.

The (c) indicator only appears when the position has been user calibrated.

The Time and Date fields show the local current time and date.

The TTG and ETA (WAYPOINT) data relates to the target waypoint. The TTG and ETA (ROUTE) data relates to the end of the route.

All data is based on the SOG towards the current target. If the SOG is negative, or data is not available, these fields are replaced with dashes, one per character.

3.6 Transferring waypoints and routes

Displayed waypoints

Waypoints and routes can be received and transmitted via NMEA, see also

Chapter 5, Section 5.4, Connecting to other equipment. The NMEA link could be to a PC.

Managing database lists

The SEND WAYPOINTS function sends all waypoints in the Waypoint List and all routes in the Route List. Sending the Waypoint List does not affect current routes.

Note: Sending the Waypoint List includes waypoints in an unsaved route.

The RECEIVE WAYPOINTS function adds waypoints and routes received via NMEA to the Waypoint List and Route List.

Note: Where multiple waypoints have the same position, the last waypoint sent is the only one included in the Waypoint List.

??To send waypoints (and route lists):

1.From chart mode, press ENTER; the primary function bar is displayed:

2.Using trackpad up/down, select WAYPOINTS.

3.Select WAYPOINT LIST.

4.To stop waypoint transfer, press ENTER.

Note: If either the Waypoint List or Route List becomes full, a warning is displayed and the operation is terminated.

3.7 Using tracks

The Track function is used to mark an on-screen trail that your vessel has followed, as if it had left a visible fixed wake.

While the track is turned on, it is recorded in the display unit???s memory. You specify the interval at which track points are made and a line is drawn on-screen between each point. Up to 2000 track points can be saved in total.

The track remains on-screen, even following a Power off/on, until you clear the track.

Using the SmartRoute function, a track can also be converted to and saved as a route which is automatically reversed, ready for use as your return voyage.

This section describes how to:

???Set up a track and specify the interval between track points.

???Clear the current track.

???Convert the track to a route (SmartRoute).

??To access the track controls:

1.From chart mode, press the PAGE key to display the chart set up function bar:

2.Select TRACK SET UP to display the Track function bar:

??To set up a track:

1.Select the INTERVAL function.

Use trackpad up/down to select the appropriate options to set either a time interval or a distance interval; press up to increase the interval or down to decrease the interval.

2.Use trackpad left/right to select TRACK ON and press ENTER. The TRACK ON text changes to indicate TRACK OFF.

Your vessel???s track is displayed on-screen with a line joining the points at the selected interval.

Clearing the current track

You can clear the current track from the screen.

??To clear the current track:

1.Select CLEAR TRACK.

The current track is cleared from the screen and memory.

2.If you do not require further track points to be placed, select TRACK OFF and press ENTER

SmartRoute enables the latest track to be converted to a route.

??To convert a track into a route:

1.Select MAKE INTO ROUTE and press ENTER.

The current track is converted to a new route, with the most recently placed track point as the start of the route, ie. the track is reversed.

If there is an unsaved current route on screen, the option to save the route is given, see Section 3.3, Working with Routes.

2.Check the calculated route and, in particular, that the route deviation from the original, given in the warning box, is within navigable limits.

3.8Man Overboard (MOB)

If you lose a person or object overboard, and need to return to the location, you should use the Man Overboard (MOB) function.

Note: To obtain MOB position, you must have a valid GPS fix.

??To initiate the MOB procedure, press and hold the GOTO key for two seconds. The system performs the following tasks automatically:

???Stops any GoTo or Follow operation.

???Selects a 1/2 nm scale (even if cartography is not available).

???Marks the current position as a temporary waypoint with an MOB symbol which replaces any current active waypoint and route.

???Displays the MOB data box, showing the bearing and range to the MOB position, the elapsed time since the MOB was initiated and COG data.

???Sends an MOB message, including bearing and range, to other units in the system, via NMEA.

Notes: (1) A suffix (c) to the POSition data indicates that the vessel???s position has been User Calibrated, see Chart Set Up, Chapter 4.

(2)The RANGE key operates normally to change chart scale.

??To cancel MOB, press and hold the GOTO key for 2 seconds.

The chart is re-drawn at its previous scale and the MOB symbol and data box are removed.

3.9Alarms

The chartplotter reports the following alarms:

The alarms are switched on or off, and the limits set, using the Chart Set Up function via the PAGE key menu, see Chapter 4.

When an alarm is triggered, the alarm buzzer sounds and a pop-up window, describing the alarm, is displayed.

?? To silence the alarm and clear the message, press any key.

Chapter 4: Setting up the chartplotter

4.1 Introduction

When you have installed your system and are familiar with its basic operation, you may wish to set it up to operate according to your requirements and display information according to your preferences.

This is achieved using the function controls which are displayed when you press the PAGE key. These settings can be changed at any time.

When you have set your preferences, they maintain until you reset them; they are retained even when the unit is powered off.

This chapter covers the following topics:

???System parameters and default settings

???Chartplotter-specific parameters and default settings

The set up parameters are divided into three sections:

???System, controlling overall functionality

???Chart, controlling the chartplotting functions, including waypoint information and vectors.

???GPS, displaying the associated GPS (RC420) receiver status and dGPS set up (RC420D).

Note: The additional TRACK SET UP function is covered in Chapter 3,

Operation.

This section provides instructions for displaying and changing the factory default values to your preferences. The following sections list the parameters and their possible settings and describe the function of each parameter in turn.

4.2System set up parameters

??To set the System default parameters:

1.From chart mode, with no function bar displayed, press the PAGE key to display the SET UP function bar:

2.Use trackpad left/right to highlight SYSTEM SET UP and press ENTER to display the System Set Up menu:

3.Use trackpad up/down to move the highlight up or down the list.

4.When the required parameter is highlighted, use trackpad left/right to step through the settings.

5.When you have reset to the required values, press ENTER to implement the change and return to the set up function bar.

6.Press CLEAR to clear the function bar and return to the chart display.

Note: You can return all the settings to their original factory settings, if required, by performing a factory reset as described in Chapter 6.

The following table lists the System menus and their options, shows the factory default settings and provides space for you to make a note of your new settings. Each parameter is described in the following subsections.

The following table lists the Chart Set up parameters and their options, shows the factory default setting and provides a space for you to make a note of your new default setting. Each parameter is described in the following subsections.

Orientation

The chart orientation is normally North Up, but can be changed to Course Up or Head Up. The orientation modes give the following displays:

???North Up: The chart is displayed with north upwards. This is the default mode and is the only mode available if there is no COG data.

???Course Up: The chart is rotated such that the currently selected course (bearing to the target waypoint) or, if no navigation function is taking place, the current COG value is shown upwards.

To update the Course Up reference whilst Course Up is the current mode, re- select COURSE UP from the set up menu.

If you select a new course, eg. a new target waypoint, the chart displays the new course upwards.

???Head Up: The chart is displayed with the vessel???s current COG upwards. As the heading changes the chart rotates periodically to maintain orientation.

Note: Head Up and Course Up modes are dependent upon a valid GPS fix.

Plotter mode

Plotter mode allows the user to zoom in beyond the level of cartography and continue to use plotter functions. The selected setting is retained when unit switched off.

Show waypoints

This option controls whether or not the waypoints are shown on the Chart display, with their appropriate symbols. The active waypoint, and waypoints in the current route, are always shown.

Waypoint symbol

This option allows selection of the symbol for waypoint display. The selected symbol is used for subsequent waypoints. Existing waypoints are not affected. The selected symbol is retained when the unit switched off.

Autozoom

When autozoom is enabled, commencing any navigation function or selecting FIND SHIP activates Autozoom. When active, this selects the chart range and position such that the vessel and the target waypoint are both on screen but at the largest scale possible. Moving the cursor off the vessel, or changing scale, deactivates Autozoom.

Chart boundaries

When ON, Chart boundary lines are shown on the screen. The selected setting is retained when the unit switched off.

Depth contours <5M

When ON, depth contours less than 5 metres are shown. The selected setting is retained when the unit switched off.

Depth contours 10M

When ON, depth contours of 10 metres are shown. The selected setting is retained when the unit switched off.

Depth contours >20M

When ON, depth contours greater than 20 metres are shown. The selected setting is retained when the unit switched off.

Position calibration

When ON, all position data is offset from WGS 84 by the amount of the selected calibration and is suffixed by (c). The selected setting is retained when the unit switched off. The default calibration offset is zero.

?? To perform position calibration:

1.Using horizontal trackpad movements, select SET CAL.

The menu is removed and a single function and help text are shown:

2.Using the trackpad, set the value of offset required. The distance and bearing of cursor from vessel is displayed in the Status Bar as BRG and RNG.

3.Press ENTER to confirm the selected offset value or CLEAR to reset the value to zero and return to the Chart Set Up menu.

An offset of 2nm or less is applied to all position data equal to the range and bearing between the WGS 84 position and the position entered. The menu returns with ON highlighted.

Note: Pressing ENTER with a selected offset of more than 2nm gives a warning message which is cleared on any key press. The Calibration Set Up mode maintains and the user can either reselect an acceptable offset or press CLEAR to reset the value to zero and return to the Set Up menu.

4.4 GPS setup

The GPS set up page provides information for the status of the tracked navigation satellites plus HDOP and satellite Fix Status. It also provides the ability to set up a Differential GPS (RC420D), by manually retuning it to a different differential beacon.

??To select GPS Set Up:

1.Press the PAGE key to display the SET UP functions:

2.Use the trackpad to highlight the GPS SET UP function and press ENTER to display the GPS SET UP menu.

The GPS Status window is displayed as shown below. This provides, for each tracked satellite, the satellite number, a graphical signal strength bar, status, azimuth angle and its elevation angle from your vessel.

Positional accuracy is dependent upon these parameters; in particular, the azimuth and elevation angles are used in a triangulation process to calculate your position. HDOP (Horizontal Dilution Of Position) is a measure of this accuracy; a higher figure signifies greater error. In ideal circumstances, the figure should be in the region of 1.0. The Fix Status can indicate:

???NO FIX, where no satellite fix can be acquired

???FIX OK, where a satellite fix has been acquired

???D-FIX, where a differential beacon fix has been acquired

The D-GPS SET UP function is also displayed, together with help text:

??To tune a differential GPS to another beacon:

1. Press ENTER; the Differential GPS Setup menu is displayed:

2.Using vertical trackpad movements, select MODE.

3.Using horizontal trackpad movements, alternates between MAN and AUTO; select MAN to set the beacon to manual tuning.

4.Using vertical trackpad movements select BEACON FREQUENCY and use horizontal trackpad movements to set the required beacon frequency. The frequency is adjustable between 283.5kHz and 325.0kHz in 0.5kHz steps.

5.Using vertical trackpad movements select BIT RATE and use horizontal trackpad movements to set the bit rate value. The bit rate value is selectable as either 100bps or 200bps.

6.Press ENTER to select the new beacon settings and return to the GPS Status window, then press CLEAR again to return to the Setup functions.

The Beacon ID indicates the beacon transmitter reference number. The received signal strength and signal to noise ratio (SNR) are indicated in dB. The SNR provides a measure of the quality of the received signal and is dependent upon signal strength. The greater the signal strength, the better the SNR is likely to be. Generally, the best signal is determined by the distance from the transmitter and the obstacles in between.

Differential Age indicates the time elapsed since the last differential beacon fix.

A list of beacon stations is available from the your local Raytheon distributor or the Raytheon Marine website: www.raymarine.com

Chapter 5: Installation

5.1 Introduction

This chapter provides instructions to assist in planning the installation of the RayChart 420 Chartplotter aboard your vessel.

Note: If you wish to practice using the RayChart 420 before installation, you can connect it, via a 1A quick blow fuse, to a 12Vdc power supply and operate it using the simulator mode, as described in Chapter 2 Getting Started.

EMC Installation Guidelines

All Raytheon equipment and accessories are designed to the best industry standards for use in the leisure marine environment.

Their design and manufacture conforms to the appropriate Electromagnetic Compatibility (EMC) standards, but correct installation is required to ensure that performance is not compromised. Although every effort has been taken to ensure that they will perform under all conditions, it is important to understand what factors could affect the operation of the product.

The guidelines given here describe the conditions for optimum EMC performance, but it is recognised that it may not be possible to meet all of these conditions in all situations. To ensure the best possible conditions for EMC performance within the constraints imposed by any location, always ensure the maximum separation possible between different items of electrical equipment.

For optimum EMC performance, it is recommended that wherever possible:

???All Raytheon equipment and cables connected to it are:

???At least 1 m (3 ft) from any equipment transmitting or cables carrying radio signals e.g. VHF radios, cables and antennas. In the case of SSB radios, the distance should be increased to 2 m (7 ft).

???More than 2 m (7 ft) from the path of a radar beam. A radar beam can normally be assumed to spread 20 degrees above and below the radiating element.

???The equipment is supplied from a separate battery from that used for engine start. Voltage drops below 10V in the power supply to our products, and starter motor transients, can cause the equipment to reset. This will not damage the equipment, but may cause the loss of some information and may change the operating mode.

???Raytheon specified cables are used at all times. Cutting and rejoining these cables can compromise EMC performance and so must be avoided unless doing so is detailed in the installation instructions.

???If a suppression ferrite is attached to a cable, this ferrite should not be removed. If the ferrite needs to be removed during installation it must be reassembled in the same position.

Suppression ferrites

The following illustration shows typical cable suppression ferrites fitted to Raytheon equipment. Always use the ferrites supplied by Raytheon.

Connections to other equipment

If your Raytheon equipment is to be connected to other equipment using a cable not supplied by Raytheon, a suppression ferrite MUST always be fitted to the cable close to the Raytheon unit.

5.2 Unpacking and inspecting the components

Unpack your RayChart 420 Chartplotter carefully. Retain the carton and packing materials in the event that you need to return the unit for service.

Check that you have all the correct system components. These depend on your system package:

Items Missing?

If any of the above items are missing or damaged, please contact your Raytheon dealer or our Product Support Department to obtain replacement parts. Please

5.3 Location

This section provides information affecting the possible location of the unit for ease of use, access for servicing and its position relative to the power supply.

Selecting the best location

The unit can be mounted using the trunnion (yoke) bracket, or panel mounted using the optional Panel Mounting Kit.

When planning the installation of your RayChart 420, the following points should be considered to ensure reliable and trouble free operation:

???Convenience: The unit should be installed in a convenient position where it can be viewed straight on or with a viewing angle of less than 35??. You may wish to apply power, before you install the unit, to determine the best viewing angle prior to fixing. The mounting location should be easily accessible to allow operation of the front panel controls.

???Access: There must be sufficient space behind the display unit to allow cable connections to the rear panel connectors, avoiding tight bends in the cable. At least 4cm should be allowed at the right to enable chart cards to be inserted and removed.

???Interference: The selected location should be far enough away from devices that may cause interference, such as motors and generators (see the EMC guidelines earlier in this section).

???Cable runs: The unit must be located near a dc power source. The power cable supplied is 1.5m, but a longer cable can be used if required. Power must be supplied via a 1A quick blow fuse or circuit breaker. Refer to Section 5.6 Cabling.

5.4 Connecting to other equipment

The unit transmits navigation and waypoint data on NMEA and, therefore, can be connected to an NMEA(1) compatible autopilot or compatible instrument repeater(s). The navigation data transmitted by the chartplotter is detailed in Appendix B to this handbook.

5.5 Mounting the chartplotter

Trunnion (yoke) mounting

The display unit can be conveniently mounted on a dash area, chart table, bulkhead or deckhead, as shown in the following diagram.

1.Loosen the trunnion knobs and remove the trunnion from the display unit.

2.Mark the locations of the trunnion screw holes on the mounting surface.

3.Use the screws supplied to fix the trunnion at the marked locations.

4.Fit the unit to the trunnion, adjust the display angle and tighten the knobs.

5.Connect the Power/NMEA and GPS cables to the unit, avoiding tight bends in the cables.

Panel mounting

CAUTION:

Make sure that there are no hidden electrical wires or other items behind the location before proceeding. Make sure that there is sufficient rear access for mounting and cabling. Allow at least 4cm at the right hand side of the display to enable chart cards to be inserted and removed.

5.6 Cabling

Introduction

The following points need to be considered before installing the system cables:

???The minimum requirements are a power cable and a connection from the associated GPS. Additional cables will be required if you are connecting to other equipment.

???All cables should be adequately cleated and protected from physical damage and exposure to heat. Avoid running cables through bilges or doorways, or close to moving or hot objects.

???Where a cable passes through an exposed bulkhead or deckhead, a watertight gland or swan neck tube should be provided.

You need to run the following cables:

???POWER/NMEA cable, supplied with the unit. This has a connector at one end for connecting to the unit and seven cores at the other for connecting the power supply and (optionally) NMEA.

???GPS cable from the associated GPS antenna with a connector at one end.

Chartplotter connectors

The following connectors are provided at the rear of the chartplotter:

???GPS, for connection to the associated GPS receiver.

???POWER/NMEA, for 12Vdc power connection and NMEA inputs/outputs.

GPS connector

The GPS connector provides power and data connections to the associated GPS (RC420) or dGPS (RC420D).

??Connect the GPS/dGPS using the attached cable, as follows:

1.Mount the GPS/dGPS according to its accompanying Installation Guide.

2.Feed the cable through to the rear of the chartplotter.

3.Coil up any unused cable in an appropriate safe space out of view. Do not bend the cable tighter than 100mm (4in) radius.

Note: If the supplied cable is too short, use an extension cable (Part# E35003) available from your local Raytheon dealer.

Connections to the GPS connector on the rear of the display unit are detailed in the following table:

POWER/NMEA connector

CAUTION:

If you do not have a breaker in your power circuit, you must fit an in-line 1A quick-blow fuse to the positive (red) lead of the power cable.

This unit is not intended for use on positive ground vessels.

The power connections should be made at a dc power distribution panel through an isolator switch, a 1A circuit breaker or a 1A quick blow fuse. Check that all connections are clean and tight.

The dc power system should be either:

???Negative ground, with the negative battery terminal connected to the vessel???s ground.

???Floating, with neither battery terminal connected to the vessel???s ground.

The chartplotter is intended for use on vessels??? dc power systems operating in the range 10.0Vdc to 18.0Vdc (ie. 12V systems, not 24V or 32V systems). A 1.5m (5ft) power cable is supplied .

If a longer power cable run is required, use the supplied power cable to connect to the unit, then use a suitable connector block to connect the free end to the extension cable. The supplied power cable has a cross-section of 2.0mm2.

Longer power cable runs may require larger wire gauges to minimise any voltage drop in the cable. In order to determine the correct supply cable size if the power cable must be extended, estimate the length of cable between the vessel???s main power source and the connector block then select the wire size indicated by the distance in the following table.

Maximum Extension Power Cable Lengths (m)

Checking the Chartplotter Operation

To confirm that your chartplotter is operating correctly, perform the following checks:

1.Without a Navionics Microchart?? card fitted, verify that the world map is visible.

2.Press the trackpad left/right, up/down and check cursor movement and normal scrolling action.

3.Insert a Navionics Microchart?? card for the area of your vessel.

Use the RANGE key to zoom-in to check that the new chart cartridge is being displayed.

4.Ensure that position data is available; use the FIND SHIP function to check that the cursor is fixed on the vessel symbol which is correctly positioned at the centre of the chart display, see Chapter 3, Operation.

Chapter 6: Maintenance & fault finding

This chapter provides information on routine maintenance and on possible causes of problems you may experience with your RayChart 420 Chartplotter.

6.1 Maintenance

Warnings

The chartplotter contains high voltage and specialised circuits only accessible to qualified service technicians - there are no user serviceable parts or adjustments and the operator should not attempt to service the equipment. The operator should not remove the rear cover .

Routine checks

The Chartplotter is a sealed unit. Maintenance procedures are therefore limited to the following periodical checks:

???Wipe the display unit clean with a damp cloth.

???Examine the cables for signs of damage, such as chafing, cuts or nicks.

???Check that the cable connectors are firmly attached and that the connections to the vessel???s dc power are clean and tight.

???Ensure that the cartridge cover is always fitted correctly.

Note: Never use chemical or abrasive materials to clean the chartplotter. If the unit is dirty, wipe it with a clean, damp cloth.

Servicing and Safety

Raytheon equipment should be serviced only by authorised Raytheon service technicians. They will ensure that service procedures and replacement parts used will not affect performance. There are no user serviceable parts in any Raytheon product.

Some products generate high voltages, so never handle the cables/connectors when power is being supplied to the equipment.

When powered up, all electrical equipment produces electromagnetic fields. These can cause adjacent pieces of electrical equipment to interact with one another, with a consequent adverse effect on operation. In order to minimise these effects and enable you to get the best possible performance from your Raytheon equipment, guidelines are given in the installation instructions, to enable you to ensure minimum interaction between different items of equipment, i.e. ensure optimum Electromagnetic Compatibility (EMC).

Always report any EMC-related problem to your nearest Raytheon dealer. We use such information to improve our quality standards.

In some installations, it may not be possible to prevent the equipment from being affected by external influences. In general this will not damage the equipment but it can lead to spurious resetting action, or momentarily may result in faulty operation.

6.2 Resetting the system

Two types of reset are available for the Chartplotter:

???Power-On Reset: When you turn the display unit off, then on again, the screen reverts to the chart display with all windows cleared.

???Factory Reset: This resets all values back to their original factory settings.

Note: Take care - factory reset clears all Waypoint and Route databases.

At power-on, the last-used values are retained for all the options, except for those listed in the following table which are reset to the factory default each time.

??To perform a factory reset:

1.Power off the unit.

2.Press and hold CLEAR whilst powering up until <Erase backup procedure> is displayed.

3.Either press CLEAR to abort Factory Reset and resume normal Power-Up or press ENTER to continue Factory Reset.

4.Press ENTER again; the unit restarts as for a first time Power Up with all values reset to their original factory settings

Note: The factory default settings are listed in Chapter 4.
