Simrad SU90 Operator Manual
When you are docking your vessel
You must never set the SU90 system to normal operation when the ship is in dry dock.
The transducer may be damaged if it transmits in open air. To prevent inadvertent use of
the SU90 system, pull out the mains plug on the Processor Unit whenever your vessel is
in dry dock. Additional precautionary measurers should be considered.

When you want to turn off the SU90 system
You must never turn off the SU90 system by means of the on/off switch on the Processor
Unit. When you do not use the SU90 system, turn it off with the button on the
Power
Operating Panel. If the transducer is lowered when you turn off the SU90 system, it is
automatically retracted to its upper position.
Note
If you turn off the SU90 system by means of the on/off switch on the Processor Unit you
can damage the software and the interface settings used to communicate with external
devices.
Manual operation of the hull unit
In the event of improper operation, the powerful electric motor on the hull unit may
cause serious damage to the equipment and/or injury to personnel. Therefore, before you
start manual operation, read carefully through the relevant operating procedures.
Note
You must familiarize yourself with the correct handling methods and the relevant safety
requirements.
Rules for transducer handling
A transducer must always be handled as a delicate instrument. Incorrect actions may
damage the transducer beyond repair. A physical blow to the transducer face may easily
damage one or more elements. Observe these transducer handling rules:
• Do not activate the transducer when it is out of the water.
• Do not handle the transducer roughly. Avoid impacts.
• Do not expose the transducer to direct sunlight or excessive heat.
• Do not damage the outer protective skin of the transducer.
