OPERATIONAL OVERVIEW
Turning the Power On/Off
Turning the power on
Press the ON switch on the main panel. The lamp above the
switch 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
switch blinks during lowering of the trans-
ducer and lights when the transducer is
completely lowered. In normal use fully
lower the transducer. The transducer ex-
tends *1200 mm below the ship’s hull, pro-
viding 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 extends *800 mm from
ship’s hull).
*Hull unit with 1600 mm (full) and 1200
mm (mid) protrusions are also available.
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.
