1.2 Turning the Power On/Off

Power on

Press the PWR switch on the main panel. The lamp above the

switch lights to show that power is turned on.

Power off

Retract the transducer with the g key on the main panel. The

lamp above the switch lights while the transducer is being raised

and goes off when the transducer is fully raised. Then, press

the PWR switch.

Note: The transducer is automatically retracted into the tank

even if the PWR switch is pressed before retracting the
