Before you turn on the SU90 system
Before you turn on the SU90 system, make sure that you have sufficient water depth to lower the transducer!
CautionYou must never turn on the SU90 system when the ship is in dry dock. The transducer may be damaged if it transmits in open air.
When the SU90 system is not used
When you do not use the SU90 system, turn it off.
NoteYou must never turn off the SU90 system by means of the on/off switch on the Processor Unit. You must ALWAYS use the Operating Panel.
When you are docking your vessel
