Bottom alarm

The bottom alarm alerts you when the bottom echo enters the alarm area. The audio alarm sounds and the visual alarm ???BOTTOM??? appears in red reverse video and flashes when the bottom alarm is violated.

Fish alarm

The fish alarm alerts you when fish echoes enter into the set alarm range. The audio alarm sounds and the visual alarm ???FISH??? appears in red reverse video and flashes when the bottom alarm is violated. This alarm is useful when targeting a specific fish specie, since each fish specie is known to inhabit certain depths.

Bottom fish alarm

The bottom-fish alarm sounds when a fish echo is within a predetermined distance from the bottom. The audio alarm sounds and the visual alarm ???BL-FISH??? appears in red reverse video and flashes when the bottom fish alarm is violated.

Temp alarm (requires temperature sensor)

There are two types of temperature alarms: within range and out of range. The audio alarm sounds and the visual alarm ???TEMP??? appears in red reverse video and flashes when the temperature alarm is violated. The temperature alarm may be used to target specific fish species, as each fish specie is know to inhabit certain temperature ranges.

V-temp alarm (requires net sonde or trawl sonar)

3.8 Target Sphere Calibration Dialog Box

To accurately analyze fish distribution, it is necessary to calibrate target strength using a calibration sphere. The calibration is done to jibe the target strength (TS) value displayed in the fish histogram dialog box with the TS of the calibration sphere.

Follow the procedure below to perform the calibration.

1.Suspend a calibration sphere at least 3 m directly below the transducer.

2.Open the fish histogram dialog box.

3.While observing the echo sounder image, adjust the area marker (yellow rectangle) to place the echo of the calibration sphere within the area marker. (See paragraph 1.12.1 for details.)

Set the marker at the right edge of the screen in order to measure with most recent data. It is recommended to make the measuring area as small as possible to keep unwanted echoes out of the measuring area, however the calibration can be performed with any size measuring area.

4.Note the TS value in the fish histogram dialog box.

There is no problem if the TS value and the TS value of the calibration sphere do not agree. Ideally, it is desirable if the distribution graph in the fish histogram window shows only one bar for the calibration sphere, however the calibration can be executed regardless of distribution.

5.Confirm that the echo from the calibration sphere appears in the area marker in consecutive scans.

6.Click System on the menu bar.

7.Click Test/Initialization.

ETR TX/RX dialog box

Click TX/RX on the System menu to show this dialog box.

Gain adjustment: Compensate for too high or too low gain and adjust gain balance of low

and high frequency. Setting range: -50 to 50.

Freq adjustment: Fine tune the Tx frequency when interference cannot be rejected

otherwise. Setting range: -10.0 to 10.0.

TX power reduction: This setting is normally ???OFF???. However, if an echo sounder of the same frequency as your own is being operated nearby, interference may appear on your display. In this case, both parties should lower their TX power to remove the interference. Turn this item ON to lower TX power.

Tx pulse length: Pulse length is automatically selected according to display range and display shift settings. For manual selection, choose a short pulse when resolution is important and choose a long pulse when long-range detection is your objective. To improve resolution on zoom displays, choose the pulse length setting Short1, Short 2 or Manual.

Short1: Detection resolution is improved, however detection range is shorter (1/4 of standard) compared to Short2.

Short2: Detection resolution is improved, however detection range is shorter (1/2 of standard).

Standard: Use for general fishing operations.

Long: Detection resolution is lower, however detection range is longer (2x normal). Depending on the range, the Tx rate is 1/2 of the normal.

Manual: Operator chooses pulse length.

3. CHANGING SETTINGS

Tx pulse length (Manual): Operative when TX pulse length is set to Manual. The pulse length range is 0.2-5(ms). The smaller the figure, the better the resolution, however the detection range is shorter. Conversely the larger the figure, the better the detection but the lower the resolution.

ETR Compensation dialog box

Draft: To get depth from the sea surface (rather than the transducer), enter ship???s draft.

Setting range: -15.0-60.0(m).

Sound velocity: Adjust the sound velocity of the Tx pulse if the depth indication is incorrect.

Setting range: 200-2000(m/s).
