Raymarine EMC Guidelines
•Raymarine specified cables are used at all times. Cutting and rejoining these cables can compromise EMC performance and so must be avoided unless doing so is detailed in the installation manual.
•If a suppression ferrite is attached to a cable, this ferrite should not be removed. If the ferrite needs to be removed during installation it must be reassembled in the same position.
Suppression Ferrites
The following illustration shows typical cable suppression ferrites fitted to Raymarine equipment. Always use the ferrites supplied by Raymarine.
Connections to Other Equipment
If your Raymarine equipment is to be connected to other equipment using a cable not supplied by Raymarine, a suppression ferrite MUST always be fitted to the cable close to the Raymarine unit.
Check 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.
Servicing
Raymarine equipment should be serviced only by authorised Raymarine service technicians. They will ensure that service procedures and replacement parts used will not affect performance. There are no user serviceable parts in any Raymarine product.
Always report any EMC related problem to your nearest Raymarine dealer. We use such information to improve our quality standards.
In some installations it may not be possible to prevent equipment from being affected by external influences. In general this will not damage the equipment but it can lead to spurious resetting action, or momentarily may result in faulty operation.
