7InstallationIf a problem is found, try altering the location of theunit or wiring. Often moving the receiver a few feet awayfrom the source of interference will solve the problem.When a suitable configuration is found, a permanent instal-lation should be made. Select the mounting location accord-ing to your preferences. Keep in mind that from this mount-ing location cables will be routed to the NMEA 0183listening device. Since mounting needs will vary, here are acouple basic methods:Mounting the GPS 16 with magnetic mount:1. Align the magnetic mount, with the protective coatingfacing away from the unit base, with the 3 screw holeson the bottom of the receiver.2. Insert and tighten the 3 screws.3. Place the receiver on a clean, metallic surface androute cable accordingly.Flush mounting the GPS 16:1. With the receiver upside down, using a piece of paper,punch holes at the 3 screw locations to create atemplate.2. Use the template to mark and drill holes large enoughfor the screw to pass through at the marked location.3. Align the receiver over the 3 holes and fasten thescrews. The M4 thread inserts for the GPS 16 are8.10mm deep. Do not use screws that will threadinto the receiver any deeper, as this may damage thereceiver.Three common sources of interference for GPS unitsare:RadarABOVE- OKBELOW- OKEMISS JAYHAWK3'VHF Radio AntennaRadarEMI (Electromagnetic Interference) from engine componentsWhen routing the power/datacable, try to avoid:• Sharp edges which may cut thecable.• Routing the cable parallel toother power lines.• Excessively twisting, strainingor bending the cable.Mounting theGPS 16I
