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).
