1.3.2 How to raise the transducer
To raise the transducer, do the following:
1. Press the XDR up key ( ) to raise the transducer. The lamp above the key
blinks to indicate that the transducer is being raised. When the transducer is com-
pletely retracted, the lamp lights steadily.

Note 1: If the automatic retraction feature is enabled, the system automatically raises
the transducer once the ship exceeds the pre-set speed. If speed data is not accurate,
the transducer may be raised at a different speed than the pre-set speed. For further
details regarding automatic retraction, see section 5.15.
Note 2: When the ship exceeds the speed set at [SPEED ALARM/MESSAGE] in the
[SYSTEM SETTING 2] menu, an audible alarm may sound. For further details see
section 5.15
