Chapter 3: Troubleshooting & Maintenance
This chapter provides information to enable you to identify problems, interpret alarm
messages, maintain your SPX-5 Sport system and obtain product support.
Raymarine products are designed to provide many years of trouble-free operation.
They are also put through comprehensive testing and quality assurance procedures
before shipping.
However, if a problem occurs with your SPX-5 Sport system, use the troubleshooting
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.
