OPERATION

PROCEDURE TO RECEIVE AND TRANSMIT

A. MICROPHONE

The receiver and transmitter are controlled by the push-to-talk switch on the microphone.

Press the PTT switch, transmitter will be activated, release switch to receive. When

transmitting, hold the microphone two inches from the mouth and speak clearly in a

normal voice. This transceiver comes complete with a low impedance dynamic

microphone.

B. PROCEDURE TO RECEIVE

1. Ensure that power source, microphone and antenna are connected to the proper

connectors before going to the next step.

2. Turn VOL knob clockwise to apply power to the radio.

3. Set the VOL for a comfortable listening level.

4. Set the MODE switch to the desired mode.

5. Listen to the background noise from the speaker. Turn the SQ knob slowly clockwise

until the noise just disappears. The SQ is now properly adjusted. The receiver will

remain quiet until a signal is actually received. Do not advance the control too far or

some of weaker signals will not be heard.

6. Set the CHANNEL selector switch to the desired channel.

7. Set the RF GAIN control fully clockwise for maximum RF gain.

C. PROCEDURE TO TANSMIT

1. Select the desired channel of transmission

2. Set the MIC GAIN control fully clockwise.

3. If the channel is clear, depress the push-to-talk switch on the microphone and speak in

a normal voice.

OPERATION

ALTERNATE MICROPHONES AND INSTALLATION

For best results, the user should select a low-impedance dynamic type microphone or a

transistorized microphone. Transistorized type microphones have low output impedance

characteristics. The microphones must be provided with a four-lead cable. The audio

conductor and its shielded lead comprise two of the leads. The third lead is for transmit

control and fourth is for receiving control.

The microphone should provide the functions shown in schematic below.

4 WIRE MIC CABLE

Mic Cable Lead

1 Audio Shield

2 Audio Lead

3 Transmit Control

4 Receive Control

Fig. 1 Your transceiver microphone schematic.

If the microphone to be used is provided with precut leads, they must be revised as

follows.

1. Cut leads so that they extend 7/16" beyond the plastic insulating jacket of the

microphone cable.

2. All leads should be cut to the same length. Strip the ends of each wire 1/8" and tin the

exposed wire.
