1.4 Raising, Lowering the Transducer
1.4.1 Lowering the transducer
CAUTION
Do not exceed 20 knots when operating
the equipment and do not exceed 15
knots when lowering or raising the
transducer.
The transducer may become damaged.
With the boat at the fishing ground, press the [↓] switch to lower the transducer. The lamp
above the switch blinks while the transducer is being lowered and lights when it is
completely lowered. The down arrow of the transducer status indicator is filled when the
transducer is completely lowered.
1.4.2 Raising the transducer
Press the [↑] switch to raise the transducer. The lamp above the switch blinks while the
transducer is being raised and lights steadily when it is fully raised. The up arrow of the
transducer status indicator is filled when the transducer is fully retracted.
Note 1: The automatic transducer retraction feature, which requires speed input, raises the
transducer when the ship’s speed exceeds the operator-set speed (between 5 and 15
knots). If speed data is erroneous the transducer may be raised at a speed different from
the speed specified. For further details about the automatic transducer retraction, see AUTO
RETRACTION on page 5-13.
Note 2: An audio alarm may sound when the ship’s speed exceeds the speed specified.
For further details, see SPEED ALARM/MESSAGE on page 5-13.
