This section describes maintenance procedures that should be performed
by the system operator.
The section also includes a detailed description of how to replace the
Sensitive element and the fuses.
All units in the GC80 system are designed for optimum safety and
reliability. However, a limited amount of preventive maintenance should
be performed to verify safe operation and durability.
If any strange motion, smell, sound or heat is generated from any unit,
please contact a Simrad dealer.
Touching internal parts may cause electric shock if power is connected to
the system, even if the POWER button is turned OFF. Do not touch any
terminal board or power supply unit while maintaining and checking the
system. If necessary, disconnect the power cable from the Control unit.
Electrostatic charges may damage components on the circuit boards
inside the units. Always wear a correctly connected earthing strap when
opening the units.
Use a vacuum cleaner with a soft brush to avoid damaging the buttons
and the panel. If required, clean the buttons and panel with a non-abrasive
cloth moistened with mild soap solution.
The connectors should be checked by visual inspection only. Push the
connector plugs into the connector. If the connector plugs are equipped
with a lock, ensure that this is in the correct position.
Vibration and shock may cause mechanical parts to loosen. All fastening
screws should therefore be checked regularly and eventually tightened.
