Chapter 3: Fault Finding & Maintenance 31EMC advice• When powered up, all electrical equipment produces electromagnetic fields.These can cause adjacent pieces of electrical equipment to interact with oneanother, with a consequent adverse effect on operation.• To minimize these effects and enable you to get the best possible perfor-mance from your Raymarine equipment, guidelines are given in the installa-tion instructions, to enable you to ensure minimum interaction betweendifferent items of equipment, i.e. ensure optimum Electromagnetic Compati-bility (EMC).• Always report any EMC-related problems to your nearest Raymarine dealer.We use such information to improve our quality standards.• In some installations, it may not be possible to prevent the equipment frombeing affected by external influences. In general this will not damage theequipment but it can lead to spurious resetting action, or momentarily mayresult in faulty operation.Product supportRaymarine provides a comprehensive customer support service, on the worldwide web and by telephone help line.
