4.1 General

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, a Simrad dealer shall be contacted.

4.2 Precautions

Touching internal parts may cause electric chock 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

when 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.

4.3 Cleaning the operator panels and the cabinet

surface

Use a vacuum cleaner with a soft brush to avoid damage to the

buttons and the panel. If required, clean the buttons and panel

with a non-abrasive cloth moistened with mild soap solution.

4.4 Checking the connectors

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 correct

position.

4.5 Checking mechanical installation

Vibration and chock may cause mechanical parts to loosen. All

fastening screws should therefore regularly be checked and

eventually tightened.
