Sending an Emergency Alarm with Voice to Follow
This feature allows you to send an Emergency Alarm to a group
of radios. Your radio’s 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”.
NOTE: Some accessories may not support “hot mic”. Check
with your dealer or system administrator for more
information.
If your radio has Emergency Cycle Mode enabled, repetitions of
hot mic and receiving period are made for a programmed
duration.
NOTE: During Emergency Cycle Mode, received calls sound
through the radio’s speaker.
If you press the PTT button during the programmed receiving
period, you will hear a prohibit tone, indicating that you should
release the PTT button. The radio ignores the PTT press and
remains in Emergency mode.
NOTE: 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.
Procedure:
1 Press the programmed Emergency On button or the
Emergency footswitch.
2 The display shows Tx Alarm and the destination alias. The
green LED lights up and the Emergency icon appears.
OR
The display shows Tx Telegram and the destination
alias. The green LED lights up and the Emergency icon
appears.
3 Once the display shows Alarm Sent, speak clearly into the
microphone. When hot mic has been enabled, the radio
automatically transmits without a PTT press until the hot mic
duration expires.
While transmitting, the green LED lights up and the
Emergency icon appears.
4 The radio automatically stops transmitting when:
Once the cycling duration between hot mic and receiving
calls expires, if Emergency Cycle Mode is enabled.
OR
Once the hot mic duration expires, if Emergency Cycle
Mode is disabled.
5 To transmit again, press the PTT button.
OR
Press the programmed Emergency Off button to exit the
Emergency mode.
6 The radio returns to the Home screen.
