4 Maintenance & Fault Finding
Chapter 4: Maintenance & Fault Finding
This chapter provides information about identifying common
problems, maintaining your autopilot system and obtaining product
support:
4.1 Fault finding
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.
In the unlikely event that a fault does occur with your autopilot, use
the following table to help identify the problem and provide a
solution.
If you cannot resolve the problem yourself, refer to the product
support information on page 32.
SYMPTOM SOLUTION
