OPERATIONAL OVERVIEW
Turning the Power On/Off
Turning the power on
Press the ON key 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 key and then press the OFF
key on the main panel.
Note: The transducer is automatically retracted into the tank even
if the OFF key is pressed before retracting the transducer. How-
ever, 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(full) or d( mid) key. 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 transducer. 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 (mid) key.
This raises the transducer by 400 mm (trans-
ducer extends 800 mm* from ship’s hull).
*: Hull unit with 800 mm (full) and 450 mm
(mid) protrusion is 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.
