necessary, replace and re-secure.
2.2 Troubleshooting
Preliminary procedures
Changes in the electronic environment may adversely affect the operation of your
ST60+ 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 are still
being met before further investigating the problem.
