Maintenance

All Raymarine products are designed to provide many years of trouble-free operation. We also put them through comprehensive testing and quality assurance procedures before shipping.

Regular checks

On a regular basis:

•check that all connections and mountings are secure and undamaged

•check the course computer for any signs of physical damage or water damage

Note: Do not use chemical or abrasive materials to clean the course computer. If the case is dirty, wipe it with a clean, damp cloth.

Fault-finding

Course computer fuses

Symptoms of a blown course computer fuse are:

•if either the power fuse or SeaTalk fuse blows, the control unit display will go blank

•if the clutch fuse blows and your drive has a clutch, the control unit will show a DRIVE STOPPED alarm message

If your control unit shows either of these symptoms, check the relevant fuse(s). If the fuse has blown, replace it with a fuse of the same current rating (see page 14).

For more information about diagnosing faults on your autopilot system, refer to the Fault Finding section of the control unit owner’s handbook.

Servicing

CAUTION:

The course computer does NOT contain user-serviceable parts. If you remove the main cover you will invalidate the warranty.
