If you press the PTT button during the programmed
receiving period, you hear a prohibit tone, indicating
that you should release the PTT button. The radio
ignores the PTT button press and remains in
Emergency mode.
If you press the PTT button during hot mic, and
continue to press it after the hot mic duration expires,
the radio continues to transmit until you release the
PTT button.
If the Emergency Alarm request fails, the radio does
not retry to send the request, and enters the hot mic
state directly.
Note:
Some accessories may not support hot mic.
Check with your dealer or system
administrator for more information.
