INSTALLATION

2.1 UNPACKING 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 PLANNING THE INSTALLATION

When planning the installation for your Ray48, the following conditions should be considered to insure dependable and trouble-free operation.

• The mounting location should be easily accessible to allow operation of the front panel.

• The radio should be located at least 3 feet from the antenna.

• There should be adequate ventilation for the control unit.

• A sufficient space should be secured behind the transceiver to allow for proper cable connections to the rear panel connectors.

• 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 and salt spray. It is always a good practice to protect your valuable electronic equipment as much as possible.

• Use adequately sized wire for all DC power connections and make sure to solder all in-line connectors or splices.

2.3.1 Typical Mounting Methods

The Ray48 can be conveniently mounted on a chart table, bulkhead, overhead, or any other desired location (refer to Figure 2-1 for typical mounting methods).

CAUTION Make sure there are no hidden electrical wires or other items behind the desired location before proceeding. Check that free access for mounting and cabling is available.

2.3.2 Flush Mounting

In addition to the typical Mounting Methods, the Ray48 may also be flush mounted using the optional Flush Mount Kit (E46034). This kit is available from Raymarine Customer Service or your local Raymarine dealer.

2.4 ELECTRICAL CONNECTIONS

CAUTION

Do not install this radio on vessels with positive ground battery systems.

2.4.1 DC Power and External Speaker Connections

The power cable comes with external speaker attachments. The power/external speaker cable provided is 6 feet long and plugs into the 4 pin connector cable at the rear panel of the radio. The RED (+) wire with an in-line fuse (10 amps) and the BLACK (-) wire of the 4 pin connector cable are used for connecting the Ray48 to the ship's 12 VDC power system. (Refer to Fig. 2-4)

Fig.2-4 POWER/EXTERNAL SPEAKER CABLE AND

4 PIN CONNECTOR CABLE

In most cases the length of the power cable should be adequate enough to reach the DC power source. If additional wire length is required, the cable can be extended by adding more cable as necessary. However, for power cable runs longer than 15 feet, larger wire diameter size should be used to prevent voltage line loss. Fig 2-5 provides recommended wire sizes to use for various cable run distances.

Fig.2-5 POWER CABLE LENGTH

Your 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 connect the power cable to the DC supply and the lug connections should be both crimped and soldered. order to insure adequate current draw to the equipment. Intermittent operation may result if an insufficient connection is made to the power source. The connection terminal should be clean, with no sign of corrosion.

This is very important in

The RED (+) wire is connected to the positive terminal of the power source or battery. The BLACK (-) wire is connected to the negative (ground) of the power source or battery. Should the power polarity be inadvertently reversed, the 10 amp. in-line fuse located in the RED (+) conductor will open. Check the input power leads for correct polarity with a VOM, reconnect the leads observing correct polarity, and replace the fuse. Be sure to use the same rate and type of fuse.

2.4.2 External Speaker Connections

The YELLOW (+) wire and GREEN (-) wire are used for connecting the Ray48 to an external speaker (Refer to Fig.2-4).

Three watts of audio output power is provided for an external 4 ohm speaker. A suitable speaker can be purchased from your local marine dealer.

Connect the YELLOW (+) wire and GREEN (-) wire to the speaker observing polarity as it is marked on the speaker. When connected, the external speaker will function simultaneously with the internal speaker.

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 department. If a longer cable length is required, RG-58 (50 ohm) coaxial cable or equivalent cable may be used for runs up to a maximum of 50 feet. If the distance required is even greater, then we recommend using low loss RG-213 or equivalent cable for the entire run in order to avoid excessive losses in power output.

If the antenna RF connector is likely to be exposed to the marine environment, a protective coating of grease (Dow Corning DC-4 or similar) can be applied to the connector before connecting it to the radio. Any other extensions or adapters in the cable run should also be protected by silicon grease and then wrapped with a waterproofing tape.

2.4.4 Antenna Mounting Suggestions

The best radio in the world is useless without a quality antenna and good location. Mounting the VHF antenna properly is very important because it will directly affect the performance of your VHF radio. A VHF antenna designed for marine vessels should be used.

• Since VHF transmissions are essentially line-of light, mount the antenna where it is free of obstructions to obtain maximum range.

• If you must extend the length of the coaxial cable between the antenna and the radio, use a coaxial cable designed for the least amount of power loss over the entire cable length.

• Keep the coaxial cable between the radio and antenna as short as possible but remember to maintain the recommended 3 feet between the radio and antenna.

Please note that some antennas are supplied with a cable that may not be altered in any way. Please check the instructions supplied with your antenna before cutting or altering the cable.

2.4.5 Grounding

While special grounding is not generally required for VHF radiotelephone installations, it is good marine practice to properly ground all electronic equipment to the ship's ground system. The Ray48 can be connected to ground by attaching a wire to one of the screws on the unit's rear panel and then to the nearest ship's ground connection point. The recommended wire to be used for such grounding is #10 AWG.

OPERATIONS

3.1 INTRODUCTION

Your Ray48 has the capability to transmit and receive on all available US and International Marine VHF radiotelephone channels. There are channels that are FCC approved but may only be used by authorized stations for specific purposes, depending on the type of vessel (commercial or noncommercial). Refer to Table 6-1. This table lists all of the marine VHF channels available in your Ray48 for US and International radiotelephone use. Full familiarization of this table is essential when selecting your channels to insure proper channel usage.
