Chapter 9: Maintenance and Problem
Solving
This chapter provides information on routine maintenance and on possible
causes of problems you may experience with your 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 display is a sealed unit. Maintenance procedures are therefore limited to
the following periodic checks:
• Wipe the display clean with a damp cloth (ensure power is off).
• Examine the cables for signs of damage, such as chafing, cuts or nicks.
• Check that the cable connectors are firmly attached.
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 usedwill not affect performance. Thereare 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
withoneanother,withaconsequentadverseeffectonoperation.Inorderto
minimisethese effects and enable youto get the bestpossibleperformance
from your Raymarine equipment, guidelines are given in the installation
instructions, to enable you to ensure minimum interaction between differ-
