Select a location away from excessive heat sources Avoid areas where there is a high flow of humid salt air Avoid places with high levels of vibrations and shocks Ensure that there is enough airflow to avoid high ambient temperatures Ensure that the cables can be connected without violating their minimum bendingradius The unit can affect magnetic compasses. The minimum compass safe distance is 0.65meters to a standard magnetic compass and 0.40 meters to a steering magneticcompass Install the R5 SUPREME transponder as close as possible to the transponder‟sVHF/GPS antennas to minimise cable loss3.8.2 R5 SUPREME Transponder MountingThe Transponder unit is secured in place using the screw holes in the four feet in the bottomcorners.Figure 3- Transponder mounting holes.
