5 Maintenance and Problem Solving

WARNING:

The display unit contains high voltage. Adjustments require specialized service procedures and tools only available to qualified service technicians - there are no user serviceable parts or adjustments and the operator should not attempt to service the equipment. The operator should not remove the aluminium front panel of the display.

Switch off the display unit before removing the power cord.

Routine Checks

The display is a sealed unit. Maintenance procedures are therefore limited to the following periodic checks:

•Examine the cables for signs of damage, such as chafing, cuts or nicks.

•Check that the cable connectors are firmly attached.

Cleaning the Display

CAUTION:

Take care when cleaning the display. Do not wipe the display screen with a dry cloth - this could scratch the screen coating.

Do not use acid, ammonia based or abrasive products.

1.Ensure the display is disconnected from power. Wipe the display with a clean, damp cloth.

2.If necessary, use IPA (iso-propyl alcohol) or a mild detergent solution to remove grease marks.

EMC Servicing and Safety Guidelines

•Raymarine equipment should be serviced only by authorized Raymarine service tech- nicians. They will ensure that service procedures and replacement parts used will not affect performance. There are no user serviceable parts in any Raymarine product.

•Some products generate high voltages, so never handle the cables/connectors when power is being supplied to the equipment.

•When powered up, all electrical equipment produces electromagnetic fields. These can cause adjacent pieces of electrical equipment to interact with one another, with a consequent adverse effect on operation. In order to minimise these effects and enable you to get the best possible performance from your Raymarine equipment, guidelines are given in the installation instructions, to enable you to ensure minimum interaction between different items of equipment, i.e. ensure optimum Electromagnetic Compat- ibility (EMC).

•Always report any EMC-related problem to your nearest Raymarine dealer. We use such information to improve our quality standards.

•In some installations, it may not be possible to prevent the equipment from being affected by external influences. In general this will not damage the equipment but it can lead to spurious resetting action, or momentarily may result in faulty operation.
