8.12 How to Raise the Transducer from the Hull Unit
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.
This procedure is intended for the service technician.
8.12.1 How to raise the transducer automatically
If the message "TRANSDUCER NOT RETRACTED" appears, and the transducer
cannot be retracted from the control unit, do as follows:
1. Turn off the switchboard, transceiver unit and hull unit from the ship’s mains
breaker.
You can force-quit the system by long-pushing the POWER ON (|) switch for ap-
prox. 10 seconds.
2. Check if the net or other object is caught in the transducer.
3. 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.
4. Unfasten six screws to remove the cover of the raise/lower control box.
