Raymarine RAY 210VHF operation manual External Speaker Connections, Antenna Connections

It is recommended that lugs be used to connect the power cable to the DC supply and that lugs should be both crimped and soldered. This is very important in 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 terminals should be clean, with no sign of corrosion.

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 connector be inadvertently reversed, the 10 amp. in-line fuse located in the RED (+) wire will open. Check the input power leads for correct polarity with a VOM (volt /ohm meter), reconnect the leads observing correct polarity, and replace the fuse. Use the same rate and type fuse.

2.4.2 External Speaker Connections

The YELLOW (+) wire and GREEN (-) wire are used for connecting the RAY210 to the external speaker. (Refer to Fig 2-4)

Four watts of audio output 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 with the speaker. The internal speaker and the external speaker will sound simultaneously.

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 may be cut to the required length at installation. 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 connector is likely to be exposed to the marine environment, a protective coating of grease (similar to Dow Corning DC-4) 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 good antenna location. Mounting the VHF antenna properly is very important because it will directly affect the performance of your VHF radio. A standard VHF antenna that is designed for use aboard boats should be used.
