Chapter 6: Maintenance & Fault Finding

This chapter provides information on routine maintenance and on possible causes of problems you may experience with your Raynav 300 GPS Plotter.

6.1 Maintenance

WARNING:

The plotter contains 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 plotter 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 con- nections to the vessel’s DC power are clean and tight.

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

EMC Servicing and Safety Guidelines

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

Some products generate high voltages, so never handle the cables/con- nectors 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 inter- act 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 enable you to ensure minimum interac- tion between different items of equipment, i.e. ensure optimum Elec- tromagnetic Compatibility (EMC).
