1.4.2 Raising the transducer
Press the key to raise the transducer. The lamp above the switch flashes and the
message "Raising " (background: green)* appears. while the transducer is being
raised. When the transducer is above the sea surface the, transmission is stopped the
message "TX STOPPED" appears for three seconds. When the transducer is com-
pletely retracted, the message "RETRACTED" appears and the lamp above the
key lights steadily.
*: Depending on the POWER OFF ( ) switch, the background color may be red when
raising the transducer.
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
The Transducer Position Mark, which appears at the top left corner, lets you check
how far the transducer is projecting. You can show or hide the marker by doing the
following operation: [Menu]
→ [Initial Settings] → (Change confirmation window) →
[Mark Display] → [TD Position Mark].

The color of the indicator changes according to transducer position and operation
state.
• Green: The transducer is fully retracted.
• Brown-yellow: Transducer stopped at position other than “retracted”.
• Red: The transducer is being raised or lowered.
If the transducer position cannot be detected the transducer mark flashes. Further, the
bar is not displayed, and the amount of projection is indicated as "**%".
