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 c switch 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
d switch. 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.
