Although every effort has been taken to ensure thatthey will perform under all conditions, it is important to understand what factors couldaffect the operation of the product.The guidelines given here describe the conditions for optimum EMC performance, butit is recognized that it may not be possible to meet all of these conditions in allsituations. To ensure the best possible conditions for EMC performance within theconstraints imposed by any location, always ensure the maximum separation possiblebetween different items of electrical equipment.For optimum EMC performance, it is recommended that wherever possible:• Raymarine equipment and cables connected to it are:• At least 3 ft. (1 m) from any equipment transmitting or cables carrying radio sig-nals e.g. VHF radios, cables and antennas. In the case of SSB radios, the distanceshould be increased to 7 ft. (2 m).• More than 7 ft. (2 m) from the path of a radar beam. A radar beam can normallybe assumed to spread 20 degrees above and below the radiating element.• The equipment is supplied from a separate battery from that used for engine start.Voltage drops below 10 V, and starter motor transients, can cause the equipmentto reset. This will not damage the equipment, but may cause the loss of some infor-mation and may change the operating mode.• Raymarine specified cables are used. Cutting and rejoining these cables can com-promise EMC performance and must be avoided unless doing so is detailed in theinstallation manual.• If a suppression ferrite is attached to a cable, this ferrite should not be removed. Ifthe ferrite needs to be removed during installation it must be reassembled in thesame position.
