1 SECTION 1 GENERAL DESCRIPTION 1.1 INTR ODUCTION Congratulations on your purchase of Raymarine's Ray48 marine radiotelephone. The Ray48 is a CPU-controlled, digitally synthesized, compact transceiver which provides reliable simplex and half-duplex (two-frequency) communications between ships and from ships at sea to public or private shore st[...]

2 SECTION 2 INST ALLA TION 2.1 UNP A CKING AND INSPECTION Use care when unpacking the unit from the shipping carton to prevent damage to the contents. It is also good practice to save the carton and the interior packing material. The original packing material should be used in the unlikely event it is necessary to return the unit to the factory . 2[...]

3 • The transceiver should be located as near to the power source as possible. • The selected location should be as far apart as is possible from any devices that may cause interference such as motors, generators, and other on board electronics. • Generally speaking, the transceiver should be protected from prolonged direct exposure to rain a[...]

6 Y our Ray48 radio should be connected to the nearest primary source of ship's DC power . A typical source may be a circuit breaker on the power panel or a fuse block near the unit. When connecting to either of these sources, the circuit breaker or other in-line fuse should be rated at 10 amps. It is recommended that terminal lugs be used to [...]

7 2.4.3 Antenna Connections The coaxial cable to your VHF antenna is intended to be connected to the antenna jack on the rear panel using a PL259 VHF type connector . The antenna cable can be cut to length but the overall cable length can be critical to performance. If you are uncertain, contact a professional installer or call our Product Support [...]
