Chapter 6: Maintenance & Fault Finding

This chapter provides information on routine maintenance and on
possible causes of problems you may experience with your Raychart 425
Chartplotter and/or its associated Raystar 120 Receiver.

6.1 Maintenance

WARNING:

The chartplotter contains high voltage and specialized circuits
only accessible 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.

Routine Checks

The Chartplotter is a sealed unit. Maintenance procedures are therefore
limited to the following periodic checks:

•

Wipe the display unit clean with a damp cloth.

•

Examine the cables for signs of damage, such as chafing, cuts or
nicks.

•

Check that the cable connectors are firmly attached and that the con-
nections to the vessel’s dc power are clean and tight.

•

Ensure that the cartridge cover is always fitted correctly.

Note: Never use chemical or abrasive materials to clean the chartplotter.
If the unit is dirty, wipe it with a clean, damp cloth.

Servicing and Safety

Raytheon equipment should be serviced only by authorized Raytheon
service technicians. They will ensure that service procedures and
replacement parts used will not affect performance. There are no user
serviceable parts in any Raytheon product.

Some products generate high voltages, so never handle the cables/
connectors 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 minimize these effects and enable you to get the best possible
performance from your Raytheon equipment, guidelines are given in the
