WARNINGS
Overvoltage Warning
If the input voltage to this unit rises above 125 VAC, the over-
voltage detection circuit activates, an alarm sounds and the mes-
sage OVERVOLTAGE appears at the screen center.
If this occurs, retract the transducer, turn the power off and check
the ship’s mains voltage. It should be about 100 VAC.
Unretracted Transducer Warning
If the transducer is not completely retracted within 30 seconds
after pressing
c, an alarm sounds and the message XDCR NOT
RETRACTED! appears at the screen center.
If this occurs, do the following:
1. The power cannot be turned off because the transducer can-
not be retracted. Turn off the main breaker for the display
and power supply units to stop operation.
2. Confirm that the net is not tangled in the transducer.
3. Confirm that the breaker inside the raise/lower control box
(mounted on the hull unit) is on.
4. Remove the cover of the raise/lower control box. Push the
(Red) reset button to reset the raise/lower control box.
5. Turn on the power and press c to retract the transducer into
the tank. If it does not retract, the main shaft of the hull unit
may be bent. Turn off the power and manually raise the trans-
ducer up to the highest position by using the hand crank.
