The receiver and transmitter are controlled by the press-to-talk switch on the 
microphone. Press the switch and the transmitter is activated, release switch 
to receive. When transmitting, hold the microphone two inches from the 
mouth and speak clearly in a normal “voice”. The radios come complete with 
low-impedance (500 ohm) dynamic microphone.  
 

B.  PROCEDURE TO RECEIVE
