7. Service visit to a vessel.
When a service visit to a vessel is made the most common fault en-countered is likely
to be poor connections or inadequate power supplies. These should be thoroughly
checked before the Service visit diagnostic procedure is carried out.
When trying to locate a fault it should be remembered that most failures will occur in
the Course Computer with the Control Units as the next most likely.
It should be noted that the calibration variables and auto deviation correction will
require re-setting if the Course Computer, Course Computer Software or its PCB are
exchanged. A procedure for carrying out this operation is given in section 3. Always
note the Course Computer calibration settings before removing from the vessel.
