BASE STATION ANTENNA

While your Transceiver is designed for mobile opera-

tion, you might wish to use it as a base station unit,

in conjunction with a 12,6 Vdc ± 10% 2 A DC power

supply. If you decide to use your Transceiver as a base

station, choose an antenna designed to operate most

eﬃciently as a base station antenna. For example, the

1/2 wave antenna is a high-eﬃciency radiator with

omnidirectional characteristics. It performs as well in

most applications as does the ground plane. You can

use this type of antenna for medium-long range com-

munications.

USING YOUR TRANSCEIVER

Do not transmit without a suitable antenna or 50 Ohm load connected to

the antenna connector.

To receive:

1. Check that the red wire is properly connected to a source of 12,6 V

± 10%.

2. Make sure that the antenna and the microphone are attached.

3. The emergency knob must be set to the central position.

4. Select the transmitting power.

5. Set the Squelch control to maximum counterclockwise position.

6. Turn on the unit by rotating the VOLUME control clockwise.

7. Set channel selector to the desired channel.

8. Adjust VOLUME for a suitable listening level.

9. Adjust Squelch to cut out annoying background noise when no si-

gnal is being received.

To do this, set the Channel Selector to a channel where no signals are pre-

sent or wait until signals cease on your channel. Then, rotate the Squelch

control in a clockwise direction to the point where the background noise
