OPERATIONAL OVERVIEW

Turning the Power On/Off

Turning the power on

Press the ON switch on the main panel. The lamp above the key should light. If it doesn’t press the TX switch on sub panel 1.

Turning the power off

Retract the transducer with the cswitch and then press the OFF key on the main panel.

Note: The transducer is automatically retracted into the tank even if the OFF switch is pressed before retracting the transducer. However, make it a habit to retract the transducer before turning off the power.

Adjusting Screen Brilliance, Control Panel Backlighting

The BRILL control adjusts screen brilliance, and the DIM con- trol adjusts control panel backlighting. These controls are on the lower part of the main panel.

Lowering the Transducer

Press d or d switch. The lamp above the key blinks during lowering of the transducer and lights when the transducer is completely lowered. In normal use fully lower the trans- ducer. The transducer extends 1200 mm below the ship’s hull, providing stable and cavitation-free soundings. If the transducer may become entangled in the net, after shooting the net, for example, partially raise the transducer with the dswitch. This raises the transducer by 400 mm (transducer ex- tends 800 mm from ship’s hull).

CAUTION

Do not exceed speed noted in the speci- fications when operating the equipment or lowering or raising the transducer.

The transducer may become damaged.

Do not press the c switch during lowering of the transducer, and do not press the d or d switch during raising of the transducer.

The equipment may become damaged.
