4 START AND STOP PROCEDURES

4.1 Start procedure

Note ! Before starting up the sonar, check that the depth of water below the

vessel is sufficient, and that the vessel’s speed is below 15 knots, which

is the maximum speed specified with the transducer lowered.

The numbers in brackets refer to figure 2.

1 Switch on the sonar by pressing the ON-OFF/HOIST

button (2) for approx. two seconds. The button lights green

to indicate that the transducer is in the upper position.

2 Set the display contrast and brightness according to

ambient light.

3 Press the LOWER button (2) until the selected transducer

position on the upper line in the menu field shows

SELECTED POS: LOWER. During the lowering, the text

will change to LOWERING TO: LOWER. When the

transducer is fully lowered, the text will change to

TRANSD.POS: LOWER. the orange LOWER button will

also light, to indicate that the transducer is fully lowered.

4 If the sonar is connected to a course gyro with stepper or

synchro output, the menu on the display will now blink

with the text: ADJUST COURSE, to remind you to adjust

the course readout on the sonar to correspond with the

course gyro. Adjust the course by means of the menu

joystick (6) and enter the value by pushing the menu

joystick to the right.

This completes the start procedure.

transducer position on the upper line in the menu field

shows SELECTED POS: UPPER. During the hoisting the

text will change to HOISTING TO: UPPER. When the

transducer is fully hoisted, the text will change to

TRANSD.POS: UPPER. the green ON-OFF/HOIST button

will also light, to indicate that the transducer is fully

hoisted.

button (2) for approx. two seconds.

WARNING ! If the Sonar Control Unit is switched OFF due to, for

example, power failure, with the Hull Unit lowered, the

Hull Unit must be raised by using the hoisting/lowering

switch in the motor control unit, or by the hand crank
