10.11.2 How to raise the transducer
If the transducer cannot be raised with the switches on the control unit, because it is
tangled in the net or its shaft is bent, try to raise it from the hull unit, automatically or
manually, whichever works.
These procedures are intended for qualified technicians.
How to raise the transducer automatically
1. Check the LEDs on the hull unit.
When the L.SW_LED on the raise/lower control box flashes, the raise/lower func-
tion may be abnormal. When you can not check the LEDs, continue to step 2.
2. Turn off the switchboard, transceiver unit and hull unit from the ship’s mains
breaker.
To force a system shut-down, press and hold the POWER ON (I) switch for ap-
proximately seven seconds.
3. Check if the net or other object is caught in the transducer.
4. Look through the lid on the raise/lower control box in the hull unit to check if the
motor breaker is OFF. If it is midway between ON and OFF, open the lid and turn
it off and then on.
5. Unfasten six screws to remove the cover of the raise/lower control box.
