Operation Manual S15 14. Installation 14.1 Unit Installation The S15 should be sited so that engine noise and vibration or other background noise does not make it difficult for the operator to hear. It is recommended that it is not installed where it will be exposed to continuous direct sunlight as this will eventually damage the LCD display. As loudspeakers contain powerful magnets, the radio should not be installed within 1m (3ft 3in) of any compasses, whether magnetic or electronic.
Operation Manual S15 On the back of the case of S15 there is a antenna socket, a power cable socket and a jack socket for an external speaker / the GPS input and NAVTEX input (Fig D). Fig D The S15 requires a 12v DC supply to operate, this lead should be connected to the vessel’s power supply (the red wire is positive, black is negative), keeping the cable runs as short as possible.
Operation Manual S15 As the range of VHF signals are governed by line of sight, the antenna should be placed as high as possible, while remaining clear of any metallic objects that could influence the resonance of the antenna. The most popular antennae for marine use are 1m (3ft 3in) long. On sail boats these are usually mounted at the masthead, where the length of the antenna keeps it clear from the navigation lights and wind vanes etc.
