3.2 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 mounting.
• 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 service technicians. They will ensure that service pro-
cedures 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 equip-
ment.
• When powered, all electrical equipment produces electromag-
netic fields. These can cause adjacent pieces of electrical equip-
ment 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
