Chapter 6: Maintenance & fault finding
This chapter provides information on routine maintenance and on possible
causes of problems you may experience with your RayChart 420 Chartplotter.
6.1 Maintenance
Warnings
The chartplotter contains high voltage and specialised 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 periodical 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
connections 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 authorised 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 minimise
these effects and enable you to get the best possible performance from your
Raytheon equipment, guidelines are given in the installation instructions, to
enable you to ensure minimum interaction between different items of
equipment, i.e. ensure optimum Electromagnetic Compatibility (EMC).
