Storing the transducer and turning off the power 3.1.3
1. Press the [SHED] key.
The hoisting mark appears on the screen while
the hoisting device buzzer buzzes for five
seconds, after which the transducer is stored
(raised). The hoisting mark turns green and the
status display area flashes. Storage is complete
after about 30 seconds. "Storage complete"
appears on the screen for a few seconds.
(Refer to 2.1.3 Examples of transducer status
displays for details about the status display.)
2. Press and hold the [POWER] key and the [PANEL] key at the same time. After the beep,
release the key. The system automatically enters the "Shutdown" state, and then, after a few
seconds, the power turns off automatically.
End
●
The ship's speed must be below 15 knots to retract the transducer with the hoisting device.
●
When the transducer is extended, pressing the [POWER] key and the [PANEL] key at the
same time stores the transducer, and after it is stored automatically turns off the power.
However, to be safe, store the transducer before turning off the power.
●
If the power does not turn off, press and hold the [POWER] key and the [PANEL] key together
for at least about seven seconds. This forces the power to turn off.
●
If you force the power to turn off but the transducer does not retract, first check that the
hoisting device is not malfunctioning. Then press the [POWER] key again to start the system
and check that the transducer retracts.
Before you turn on the power to start the system, be sure there are no people around the
hoisting device. The hoisting device starts storing (raising) the transducer, if it is extended,
when you turn on the power.
●
If the hoisting device does not store the transducer, refer to the section on repairing
malfunctions in the hoisting device to store it. If you cannot store the transducer even after
repairing the malfunction, contact your retailer or a service representative.
