message "RAISING " appears. while the transducer is being raised. When the trans-
ducer is above the sea surface the, transmission is stopped the message "TX
STOPPED" appears for three seconds. When the transducer is completely retracted,
the message "RETRACTED" appears and the lamp above the
key lights steadily.
Note: If the transducer is not raised within approx. 20 seconds (1200 stroke) or 25
seconds (1600 mm stroke) the message "TRANSDUCER NOT RETRACTED" ap-
pears. If this occurs, see section 8.12.2 for how to retract the transducer manually.
1.4.3 How to check how far the transducer is projecting

how far the transducer is projecting. You can show or hide the marker by doing the
following operation: [Menu]

state.
• Green: The transducer is fully retracted.
• Brown-yellow: Transducer stopped at position other than “retracted”.
