ST60 Compass Instrument Owner’s Handbook
2.2 Troubleshooting
Preliminary procedures
Changes in the electronic environment may adversely affect the operation of your
ST60 Compass instrument equipment. Typical examples of such changes are:
• Electrical equipment has recently been installed or moved aboard your vessel.
• You are in the vicinity of another vessel or shore station emitting radio signals.
If you appear to have a problem, first ensure that the EMC requirements (see
Chapter 3, Installation
) are still being met before further investigating the
problem.
Fault location
All Raymarine products are subjected to comprehensive test and quality
assurance programmes prior to packing and shipping. If a fault arises with the

cause and provide the most likely cure.
