VHF NX2000 2 English INTRODUCTION The NX2000 is a Class-D Digital Selective Calling (DSC) VHF marine transceiver. Comprised of a VHF marine Radio and a DSC controller, it is very convenient and easy to use. The transceiver is a 1/25-watt, frequency modulated waterproof transmitter/receiver for operations on all currently allocated marine channels as well as 10 expansion channels. The NX2000 supports the latest GMDSS requirement for non-SOLAS vessels from the International Maritime Organization (IMO).

VHF NX2000 English 15 INSTALLATION 15.1 Unit Installation The NX2000 should be sited so that engine noise and vibration or other background noises do not make it difficult for the operator to hear. It is recommended not to install the unit 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.
English 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.
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. Longer whip antenna are recommended for larger boats.
