Context
The hull unit provided with the CS90 is designed to lower the transducer down below the ship’s hull when the CS90 shall be used. When the CS90 is switched off, the transducer is hoisted for protection.
CautionIf the transducer hits larger objects or bottom, the transducer shaft may be bent, or - in worst case - it can be broken off.
A broken transducer shaft will cause water leakage through the top of the shaft. If you suspect that the transducer shaft
is seriously damaged with holes, do not retract the transducer to its upper position.
To prevent serious damage to the vessel or the vessel stability, you must have a water pump and a warning system in the sonar
room.
Further requirements
The choices you make on the Hull Unit Configuration page are vital for all CS90 operation. You must only make these choices once. Accidental changes to the hull unit settings may cause damage to your CS90.
