Prerequisites
You need a ratchet with a 13 mm (½ inch) socket.
Procedure

Make sure that the SY50 system is turned off.
Do not lower or hoist the transducer manually unless you have first disconnected all power. Make sure that all power to the hull unit is disconnected. Disengage the circuit breaker in the Power Supply Unit.

2 |
Remove the protective cap on the top cover. |
|
3 |
Use a 13 mm (½ inch) ratchet to rotate the hoisting spindle. |
|
4 |
Hoist the transducer to its upper position. |
|
5 |
Replace the protective cap on the top cover. |
|
6 |
Turn on power to the hull unit.
NoteIt is crucial that the power to the hull unit is always turned on, even when the sonar is not in use. If the power is turned off, the force of gravity may cause the transducer to be inadvertently lowered. The sonar has a safety function that will automatically hoist the transducer if unexpected problems arise. This function prevents the transducer from being lowered when the sonar is not used, but the power must be turned on.
