1.3.1 Lowering the transducer
With the boat at the fishing ground, press the [ ] or [ ] key. The lamp above the
key pressed blinks during lowering and lights when the transducer is completely
lowered to selected protrusion distance. It takes about 21 seconds for full
protrusion in case of 800 mm stroke and 28 seconds in case of 1100 mm stroke.
In normal use fully lower the transducer. If the transducer becomes entangled in
the net for some reason, partially raise the transducer with the [ ] key. This
raises the transducer by 400 mm.
1.3.2 Raising the transducer
Press the [ ] key to raise the transducer. The lamp above the switch blinks while
the transducer is being raised and lights steadily when it is fully raised.
1.4 Screen Brilliance
The [BRILLIANCE] control adjusts screen brilliance. Adjust it to suit lighting
conditions.
Note: The brilliance of an external monitor cannot be adjusted with the
[BRILLIANCE] control. Use the associated control on the monitor.
