Sending Emergency Alarms with Voice
to Follow
This feature allows you to send an Emergency Alarm with
Voice to Follow to a group of radios. Your radio microphone
is automatically activated, allowing you to communicate
with the group of radios without pressing the PTT button.
This activated microphone state is also known as hot mic.
If your radio has Emergency Cycle Mode enabled,
repetitions of hot mic and receiving period are made for a
programmed duration. During Emergency Cycle Mode,
received calls sound through the speaker.
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.
NOTICE:
Some accessories may not support hot mic. Check
with your dealer or system administrator for more
information.
