the radio generates short beep three times. To be clear of activity,
release the
PTT
button and wait for the channel.
If the Busy Tone Lockout (BTL) feature is programmed on the channel,
the radio can transmit only when there is no carrier being received or
when the carrier being received includes the correct tone (CTCSS tone
or DCS code) on the channel.
