7InstallationIf a problem is found, try altering the location of the unitor wiring. Often moving the antenna a few feet away from thesource of interference will solve the problem. When a suitableconfiguration is found, a permanent installation should bemade. Select the mounting location according to your prefer-ences. Keep in mind that from this mounting location cableswill be routed to the NMEA listening device.Mounting the GPS 17 with cable outside mount:1. Place the cable in the vertical slot along the side of thebase of the unit.2. Screw the GPS 17 onto the mount. Make sure that youdo not overtighten the head. It is possible to tighten theunit to the point that the cable may be cut in two.3. With the GPS 17 and mount installed, fill the remaininggap in the cable exit on the with a marine sealant.4. Route the power/data cable from the GPS 17 to thedesired device. Excess cable may be shortened or coiledtogether and secured in an inconspicuous location.Three common sources of interference for GPS units are:RadarABOVE- OKBELOW- OKEMISS JAYHAWK3'VHF Radio AntennaRadarEMI (Electromagnetic Interference) from engine componentsWhen routing the power/datacable, try to avoid:• Sharp edges which may cutthe cable.• Routing the cable parallel toother power lines.• Excessively twisting, strainingor bending the cable.Mounting theGPS 17I
