Make sure that ample clearance is provided under the transducer when you are placing the vessel in dry dock.
Do not place supporting blocks or structures in the vicinity of the transducer.
The location of the transducer must be noted on the vessel’s docking plan for future reference.
Prior to dry docking, power down the MS70. Disengage the circuit breaker if necessary. Label the Processor Unit and/or the circuit breaker clearly to prevent anyone from powering up the MS70 accidentally.
