Page 40: Installation
Radio can be adjusted by slackening the clamp. Fig A Fig C Fig B On the back of the NX2000 there is an antenna socket, a power cable socket (Fig D) and an external speaker and GPS input socket. -
Page 41: Antenna Installation Recommendations
VHF NX2000 Fig D The NX2000 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), and the cable kept as short as possible. Although the Radio draws very little current when receiving, a heavier current is drawn when transmitting which may result in a voltage drop if very long cables are used of inadequate core diameter. - Page 42 VHF NX2000 English The most popular antenna 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. This type of antenna can also be mounted on the cabin roof or radar arch on powerboats.
