2.2 Fault finding
Preliminary procedures
Changes in the electronic environment may adversely affect the oper-ation 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 (see
Chapter 3, Installation
) are still being met before further investigating the
problem.
