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.
