PROCEDURE TO RECEIVE AND TRANSMIT

A. MICROPHONE

The push-to-talk switch on the microphone controls the receiver and transmitter.

Press the switch and the transmitter is activated, release switch to receive. When

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

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

microphone.

B. PROCEDURE TO RECEIVE

1. Be sure 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 the weaker signals will not be heard.

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

C. PROCEDURE TO TRANSMIT

1. Select the desired channel of operation.

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.

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 the schematic below.

If the microphone to be used is provided with pre-cut 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.
