4.2 Maintenance
Warnings
The display unit and scanner unit contain
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 or any internal covers in the
scanner.
Always turn 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 radar scanners are sealed units. Maintenance procedures are therefore
limited to the following periodical checks:
• 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 and pedestal are still attached securely to the mount-

• Once a year, remove, grease and re-attach the mounting bolts securing the
scanner and pedestal.
Servicing and Safety
• Raymarine equipment should be serviced only by authorized Raymarine ser-
vice technicians. 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/connec-
tors when power is being supplied to the equipment.
• When powered, 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 minimize
these effects and enable you to get the best possible performance from your
Raymarine equipment, guidelines are given in the installation instructions, to
