Startup screen

After the completion of the startup test, a timer displays the time remaining for warm up of the magnetron (the device which transmits radar pulses), counting down from 1:00 to 0:00.

To turn off the power, press and hold down the [POWER/BRILL] key (about three seconds) until the screen goes blank.

Provided that the radar was once in use with the transmitter tube (magnetron) still warm, you can turn the radar into TRANSMIT condition without 1-minute of warm-up. If the [POWER/BRILL] switch was accidentally turned off and you want to restart the radar promptly, turn on the [POWER/BRILL] switch not later than 15 seconds after power-off.

Note 1: In a cold environment the screen appears ???foggy??? when the power is turned on but is soon restored to normal condition.

Note 2: The example screens shown in this manual may not match the screens you see on your display. The screen you see depends on your system configuration and equipment settings.

1.4 Transmitting, Standby

After the power is turned on and the magnetron has warmed up, ???ST-BY??? (Stand-by) appears, indicating the radar is ready to transmit radar pulses.

To toggle between transmit and stand-by, do the following:

1.With the power turned on, press the [POWER/BRILL] key momentarily to show the brilliance/contrast adjustment window.

2.Press the [MODE] key to go to stand-by and transmit status alternately.

Note: If you attempt to transmit before ???ST-BY??? appears, the beeps sound and the radar does not transmit pulses. Wait until ???ST-BY??? appears.

3.Press the [MENU/ESC] key to close the window.

When radar pulses are transmitted the radar receiver is automatically tuned. Echoes appear in four levels of digitized video according to echo strength. When a target is beneath a marker (VRM, EBL, heading line, range ring) the part of the marker where the target lies is displayed in reverse video.

Note 2: The radar starts up with the last-used brilliance level after the startup screen appears. Therefore, adjust the brilliance if it is too low at startup.

1.6 Choosing the Range

The range selected automatically determines the range ring interval, the number of range rings and pulse repetition rate.

Press the [RANGE+] or [RANGE-] key to choose the range. The range and range ring interval appear at the top left corner on the screen.

Location of range and range ring interval indications

1.7 Receiver Sensitivity

The [GAIN] key adjusts the sensitivity (gain) of the receiver. It works in precisely the same manner as the volume control of a broadcast receiver, amplifying the signals received.

To set the sensitivity, you first choose the automatic sensitivity setting which best matches current sea condition. Then, if necessary, you may fine tune the sensitivity manually. The proper setting is such that the background noise is just visible on the screen.

If you set up for too little sensitivity, weak echoes may be missed. On the other hand excessive sensitivity yields too much background noise; weak targets may be missed because of the poor contrast between desired echoes and the background noise on the display.

1.Press the [GAIN] key consecutively until the display shown below appears.

3. Press the [MENU/ESC] key to finish.

1.8 Suppressing Sea Clutter

In rough weather, returns from the sea surface, called sea clutter, are received over several miles around own ship and mask nearby targets. This situation can be improved by properly suppressing the sea clutter with the A/C SEA control.

To set the A/C SEA, you first choose the automatic A/C SEA setting which best matches current sea conditions. Then, if necessary, you may fine tune the A/C SEA manually.

In most cases suppress the clutter until it has disappeared to leeward, but a little is still visible windward. If the setting is too low, targets will be hidden in the clutter, while if it is set too high, both sea clutter and targets will disappear from the display.

A common mistake is too over-suppress sea clutter so that it is completely removed. You can see how dangerous this can be by setting up for maximum A/C SEA: A dark zone will be created near the center of the screen,

causing a loss of close-in targets. This dark zone is even more dangerous if the sensitivity has not been properly adjusted.

Always leave a little sea clutter visible on the screen, first adjusting automatically and then fine tuning with the manual control as necessary.

4. Press the [MENU/ESC] key to finish.

1.9 Suppressing Rain Clutter

The vertical beamwidth of the antenna is designed to see surface targets even when the ship is rolling. However, by this design the antenna will also pick up rain clutter (rain, snow, or hail) in the same manner as normal targets. The illustration below shows the appearance of rain clutter on the display.

The A/C RAIN control adjusts the receiver sensitivity as the A/C SEA control does but rather in a longer time period (longer range). The higher the setting the greater the anti-clutter effect.

1.OPERATION

1.20Guard Alarm

The guard alarm allows the operator to set the desired range and bearing for a guard zone. When ships, islands, landmasses, etc. violate the guard zone, audio and visual alarms are released to call your attention. The alarms will be released for targets entering or exiting the zone depending on the presence or absence of targets in the zone when the alarm is set.

NOTICE

*The alarm should not be relied upon as the sole means for detecting possible collision situations.

*A/C SEA, A/C RAIN, FTC and GAIN controls should be properly adjusted to be sure the weak echoes will not be missed by the alarm.

How guard zone type is determined

After the guard zone has been set, the radar checks for targets inside the guard zone, which takes about 8 to 12 seconds. When the check is completed, ???G(IN)??? or ???G(OUT)??? replaces G(---) at the top right corner.

G(IN): When no target exists in the zone, "G(IN)" appears. The audio alarm sounds against targets which enter the guard zone. G(OUT): If there are targets in the guard zone, "G(OUT)" appears. The audio alarm sounds against all targets which exit from the guard zone.

Setting a guard zone

1.Operate the cursor pad to place the cursor at the top left corner for the zone and then press the [ALARM] key.

2.Operate the cursor pad to place the cursor at the bottom right corner for the zone and then press the [ALARM] key.

How to set a guard zone

(a) Inward target alarm (b) Outward target alarm

Inward and outward alarms

Note: The guard zone disappears when it is not within the range in use. When this occurs "UP RNG" replaces G(IN) or G(OUT).

Change the range to redisplay the guard zone.

Silencing the audio alarm

When a target violates the guard zone, the target flashes and the audio alarm sounds. You can silence the audio alarm with the [ALARM] key. The target continues flashing until it no longer violates the guard zone or the guard zone is canceled.

Canceling the guard zone and guard alarm

Press and hold down the [ALARM] key until the guard zone is erased.

1.21 Watchman

The radar "wakes up" at specified time intervals (5, 10, or 20 minutes) and operates for 10 scans, the start of which is announced by releasing the audio alarm. If change is found in the guard zone from the previous 10 scans, the audio alarm sounds and the radar resumes normal operation, canceling the watchman mode. If no change is found, the radar goes into stand-by, for the specified time interval. This feature is useful for periodic watch of the guard zone.

EBL REFERENCE: The EBL readout may be chosen from relative (relative to own ship???s heading) or true (referenced to the North). Heading data required for true bearing.

Note: If no bearing data is input, course data from the GPS navigator is used. In this case ship???s speed must be more than two knots.

BEARING READOUT: Course indication may be shown in true or magnetic (magnetic compass) degrees. Heading data required for true degrees.

CURSOR POSITION: Chooses the information to show for the cursor position: latitude and longitude or range and bearing from own ship. Latitude and longitude position requires a navigator.

TRIP SOURCE: Chooses the criteria for

calculating distance run: latitude and longitude or speed. Requires navigator or speed log.

WIND SPD/DIR: True is the speed and direction (in relation to ship???s bow) of the wind felt or measured when stationary. Apparent is the direction (in relation to ship???s bow) and speed of the wind as it appears to those on board, relative to the speed and direction of the boat; combination of the true wind and the wind caused by the boat???s movement. Requires wind data.

SHIFT MODE: Own ship position, or sweep origin, can be displaced manually or automatically. For automatic displacement, the amount of shift is calculated with ship speed, and the amount is limited to 60% of the range in use. For example, if the ???Auto Shift Speed??? setting is 15 knots and the ship is running at 10 knots, the amount of shift will be about 40%. The formula for determining shift amount is as below. Requires speed data.

3. INSTALLATION

3.1 Antenna Unit Installation

Mounting considerations

When choosing a mounting location for the antenna unit, keep in mind the following points:

???Install the antenna unit on the hardtop, radar arch or on a mast on an appropriate platform. (For sailboats, a mounting bracket is optionally available.) It should be placed where there is a good all-round view with, as far as possible, no part of the ship???s superstructure or rigging intercepting the scanning beam. Any obstruction will cause shadow and blind sectors.

???In order to minimize the chance of picking up electrical interference, avoid where possible routing the antenna cable near other electrical equipment onboard. Also, avoid running the cable in parallel with power cables.

???Separate the antenna unit from a magnetic compass by the distances noted below to prevent interference to the magnetic compass:

Standard compass: 1.25 m

Steering compass: 0.85 m

Mounting on a platform

1.Remove mounting hardware at the bottom of the antenna unit; four each of hex bolts (M10X20), spring washers and flat washers. Save mounting hardware to use it to fix the antenna unit to the mounting platform later on.
