From manual:
• 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.
Typical used to be yottie job.
