Chapter 9: Maintenance and Problem
This chapter provides information on routine maintenance and on possible
causes of problems you may experience with your SL72 PLUS Radar or
SL72RC PLUS Combined Radar/Chartplotter system.

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.
Always switch the radar system off before carrying out any routine
maintenance on the scanner or nearby equipment.
Switch off the display unit before removing the power cord.

Routine Checks

The LCD display and radome scanner are sealed units. 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.
• Make sure the scanner is still attached securely to the mounting.
• Once a year remove, grease and re-attach the mounting bolts securing the
scanner.

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
