Chapter 4: Fault Finding & Maintenance
All Raymarine products are designed to provide many years of troublefree
operation. We also put them through comprehensive testing and quality
assurance procedures before shipping.
This chapter provides information about identifying problems, interpreting alarm
messages, maintaining your SmartPilot and obtaining product support.
If a fault occurs with your SmartPilot, use the fault finding tables in this section to
help identify the problem and provide a solution.If you cannot resolve the
problem yourself, refer to the product support information.
