Cabling

Examine all cables for chafing or other damage to the outer shield and, where necessary, replace and re-secure.

2.2Fault 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.
