Lowering the transducer

Set ship's speed under 16 knots and then press the  switch. The lamp above the
switch flashes, and lights when the transducer is fully lowered. If you press the 
switch when the speed is over 16 knots and the speed warning is turned on in the
[SYSTEM] menu, the message "Max allowable speed for extended transducer is
16 kn. Max allowable speed during raising lowering transducer is 16 kn." and the audio
alarm sounds. Press the R/B key to silence the audio alarm.
Note: The audio alarm may be set to sound and a message displayed when the ship's
speed goes higher than maximum allowable speed. For further details, see [SPEED
