c, XDCR NOT RETRACTED! blinks at
the screen center and the alarm sounds. If this occurs do the
following:
1. The power switch cannot be turned off because the trans-

transceiver unit to stop operation.
2. Confirm that the net is not entwined around the transducer.
3. Confirm that the breaker inside the hull unit is on.
4. Check the mains fuse in the transceiver unit.
5. Apply the power again. Check if the transducer is retracted
in the tank. If it is not, the main shaft may be bent. Cut off
the power again and manually raise the transducer up to the
highest position possible by the hand crank. See the next
page for instructions.
