Turning on the entire system: Introduction
When the relevant system units have been turned on individually, you can turn on the entire
system for the first time. It is very important that this does not take place while the vessel is
in dry dock. The transducer may be damaged if it transmits in open air.
In order to turn on the MF90 system for the first time in a controlled manner, two tasks must
be done simultaneously.
Two persons are needed.
• One person must stay on the bridge in order to operate the MF90 system.
• One person must stay in the sonar room to make sure that the MF90 system starts, and
that the hull unit works properly.
Proper oral communication must exist between the bridge and the sonar room.
Certain steps in the procedures are location specific. The steps marked [ Sonar room ] are
done in the sonar room. The steps marked [ Bridge ] are done on the bridge.
Note
In the event of problems or malfunctions:
1 Locate the
Motor Protecting Switch
(S301).
2 Set the switch to position OFF.
WARNING
The transducer may be damaged if it transmits in open air.
