Each hull unit (except SU94) can be supplied with 4.6 or 7 m transducer cable. The SU94 is only supplied with 4.6 m transducer cable.
When the sonar is switched on, press the Down button on the Operating Panel to lower the transducer into the water. Before the sonar is switched off, press the Up button on the Operating Panel to retract the transducer into the installation trunk for protection. If you forget this, the transducer is hoisted automatically before the sonar is switched off. It is also hoisted automatically if a serious malfunction occurs to the communication between the bridge and the hull unit.
The transducer can also be lowered to any selected middle position. In case of voltage failure, the transducer can be raised or lowered manually by means of a hand crank.
