10.11 Raising the Transducer from the Hull Unit
If the transducer cannot be raised with the switches on the display 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.
10.11.1 Raising the transducer automatically
1. Turn off the display unit, power unit and hull unit from the breaker on the
ship’s mains. (If the transducer cannot be retracted power to the display unit
cannot be shut off.)
2. Check if the net or other object is caught in the transducer.
3. Look through the lid on the hull control 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 on
again.
4. Unfasten six screws to remove the cover of the hull control unit.
5. Push the RESET button (green) on the hull control unit.
6. Close the cover.
7. Turn on the breaker at the ship’s mains.
8. Turn on the equipment from the display unit.
9. Press the [ ] key on the display unit to raise the transducer.
If the transducer cannot be raised, the shaft may be bent. In this case raise it
manually with the hand crank, following the instructions on the next page.
