series display unit.
9.1 Maintenance
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 rear cover of the display.
Switch off the display unit before removing the power cord.
Routine Checks
The LCD 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.
• Wipe the display clean with a damp cloth.
EMC Servicing and Safety Guidelines
• Raymarine equipment should be serviced only by authorized Raymarine
service technicians. They will ensure that service procedures and replace-
ment 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/connec-
tors 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 differ-
ent items of equipment, i.e. ensure optimum Electromagnetic Compatibil-
ity (EMC).
• Always report any EMC-related problem to your nearest Raymarine
dealer. We use such information to improve our quality standards.
