4.7 Connections
Refer to the following diagram:
4.7.a Power Supply
The transceiver power supply must be 12Vdc. The red cable must be connected to the positive pin,
the black to the negative pin.
Warning! A faulty connection may seriously damage the radio!!
The power cable is equipped with a protection fuse. If the fuse shorts, look for its reason
before substituting the cable with a new one of the same type and value. Never short-
circuit it, as this may damage the radio. We suggest using the supplied cable.
4.7.b GPS device
If your NEPTUNE 100 transceiver is connected to a GPS receiver, such as the GR213, you can
obtain and view NMEA information relative to the current position the vessel (latitude and longitude)
and the local time with respect to Greenwich Mean Time (GMT).
4.7.c Antenna
The antenna is an extremely important part of the device and noticeably inuences the settings of
any telecommunications device. Contact your supplier regarding the antenna and request advice
about how to mount and best connect it to your transceiver.
Warning! Ensure the antenna is in perfect working order. It may otherwise seriously
damage the radio! A periodical measurement of the stationary waves is advised using a
suitable SWR metre.
