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 Making a Radio Call on page 25).

If the Talk Permit Tone (see Turning the Talk Permit Tone On or Off on page 83) is enabled, wait until the short alert tone ends before talking .

During a call, if the Channel Free Indication feature is enabled on your radio (programmed by your dealer), you will hear a short alert tone the moment the target radio (the radio that is receiving your call) releases the PTT button, indicating the channel is free for you to respond.

You will also hear a continuous talk prohibit tone, if your call is interrupted, indicating that you should release the PTT button, for example when the radio receives an Emergency Call.
