transmitter. When pressing down on the PTT switch the transmitter is
activated, release the PTT 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. For installation instructions on other microphones, see next
section, “ALTERNATE MICROPHONES AND INSTALLATION”.
