Raymarine EMC Guidelines• Raymarine specified cables are used at all times. Cutting and rejoining these cables cancompromise EMC performance and so must be avoided unless doing so is detailed inthe installation manual.• If a suppression ferrite is attached to a cable, this ferrite should not be removed. If theferrite needs to be removed during installation it must be reassembled in the sameposition.Suppression FerritesThe following illustration shows typical cable suppression ferrites fitted to Raymarineequipment. Always use the ferrites supplied by Raymarine.D3548-2Connections to Other EquipmentIf your Raymarine equipment is to be connected to other equipment using a cable notsupplied by Raymarine, a suppression ferrite MUST always be fitted to the cable close tothe Raymarine unit.Check Before Going to SeaAlways check the installation before going to sea to make sure that it is not affected byradio transmissions, engine starting etc.ServicingRaymarine equipment should be serviced only by authorised Raymarine servicetechnicians. They will ensure that service procedures and replacement parts used will notaffect performance. There are no user serviceable parts in any Raymarine product.Always report any EMC related problem to your nearest Raymarine dealer. We use suchinformation to improve our quality standards.In some installations it may not be possible to prevent equipment from being affected byexternal influences. In general this will not damage the equipment but it can lead tospurious resetting action, or momentarily may result in faulty operation.Document number: 84018-5Date: May 2001
