GEAR SYMBOL

The gear symbol can be a seine circle or a trawl symbol,

depending on the selection in the GEAR menu.

Seine circle:

To set a seine symbol, first press the GEAR button once. The

button lights, and the seine circle appears in front of the ship

symbol, on the side that is selected in the GEAR menu. The seine

circle will now follow the ship’s movements.

At the moment the setting of the seine starts, press the GEAR

button again. The seine circle will now be stationary to indicate

the ideal ship’s path for the seine setting. A square symbol

indicates the starting point, another square shows the half-seine

out, and a third square shows the end of the seine.

Trawl symbol:

The trawl data can be set manually in the GEAR menu, or

automatically by connecting the SIMRAD FS 3000 or ITI trawl

monitoring system to the sonar system.

In the manual mode, the trawl symbol will be displayed on the

ship’s course line, with the selected depth and distance.

If the FS 3000 trawl sonar is connected, the trawl symbol will

automatically be displayed in correct depth in the vertical display

modes.

If the ITI trawl system is connected, the trawl symbol will be

displayed with correct distance, bearing and depth. In addition,

thetrawlopening, temperature,andtrawlfilling indicatormaybe

displayed.

Press the GEAR button to set the trawl symbol. The button lights

and the trawl symbol appears on the display.

In the OMNI/VERTICAL mode, a long-dashed line will indicate

the bearing of the left-hand side vertical slice. The first time the

GEAR button is pressed, this line will become white and a 180°

extension of the audio line. The second operation of the GEAR

button will lock the left-hand slice to the trawl symbol, and the

colour of the line will change to yellow.
