You should find all of the following items in the package with your radio.

Installation and Connection

•

Refer to the illustration on page A2 for connection points on the back of the
unit while installing your radio.

--

4Location

Plan the location of the transceiver and microphone brackets before starting the installation.
Select a location that is convenient for operation and does not interfere with the driver or
passengers in the vehicle. In automobiles, the transceiver is usually mounted below the
dash panel, with the microphone bracket beside it.

--

4Mounting

Your mobile radio is supplied with a universal mounting bracket. When mounting the bracket
and radio to your car, make sure it is mechanically strong. Also provide a good electrical
connection to the chassis of the vehicle. Proceed as follows to mount the transceiver:

--

4Mount the Transceiver

1. After you have determined the most convenient location in your vehicle, hold the mobile
radio with the mounting bracket in the exact location desired. If nothing will interfere
with mounting it in the desired position, remove the thumbscrews and use the
mounting bracket as a template to mark the holes for the mounting screws. Before
drilling the holes, make sure nothing behind the surface will be damaged or interfere
with the installation.

2. Connect the antenna cable plug to the standard receptacle (ANT) on the rear panel.
Most antennas are terminated with a type PL-259 plug and mate with the receptacle.

3. Connect the red DC power input wire (with the fuse) to +13.8 V DC. This wire extends
from the rear panel. In automobile installation, connect directly to positive terminal
(red) of the vehicle's battery. We recommend that you install a fuse within six inches
of the battery.

4. Connect the black lead to -13.8 V DC to the negative (black) post of the battery.

5. Mount the microphone bracket on either side of the transceiver, using the two screws

supplied. When mounting in an automobile, place the bracket under the dash so the
microphone is readily accessible.

6. Attach the microphone cable to the connector on the face of the transceiver.

NOTE

If the radio is to be used to send Morse code, an optional telegraph
key will need to be connected to the CW Key Connector on the back
of the unit.
