Push-To-Talk (PTT) Button
The PTT button on the side of the microphone
serves two basic purposes:
• While a call is in progress, the PTT button allows
the radio to transmit to other radios in the call.
Press and hold down PTT button to talk. Release
the PTT button to listen. The microphone is
activated when the PTT button is pressed.
• While a call is not in progress, the PTT button is
used to make a new call. See Methods to Make a
Radio Call on page 56 for more information.
