If the Talk Permit Tone or the PTT Sidetone 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

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
