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.
