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-findin g

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 page14).

Servicing

CAUTION:
The course computer does NOT contain user-serviceable parts.
If you remove the main cover you will invalidate the warranty.
ÍFor more information about diagnosing faults on your autopilot system,
refer to the Fault Finding section of the control unit owner’s handbook.
