Transducer status indicator
2. Press the [POWER] switch after the lamp above the [©
] switch lights steadily.
Note 1: The transducer is automatically retracted into the tank if the [POWER] switch is
pressed before retracting the transducer. However, for safety purposes, make it a
habit to retract the transducer before turning off the power.
Note 2: After changing settings, wait at least one minute before turning off the equipment to
allow the equipment to memorize settings. This will enable the equipment to start
up with the last-used settings. No harm will result to the equipment if this is not
done.
Note 3: The hull unit remains powered when power is turned off at the control unit.
Therefore, if the sonar is not to be used for a long period turn it off at ship’s mains
switchboard.
