EMC Checks Before Going to Sea
Always check the installation before going to sea to make sure that it is not
affected by radio transmissions, engine starting etc.
In some installations, it may not be possible to prevent the equipment from
being affected by external influences. In general this will not damage the
equipment but can lead to it resetting, or momentarily may result in faulty
operation.
