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.
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:
1Press the programmed Emergency On button.
2The LED lights up solid green.
3Once a tone sounds, 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 LED lights up solid green.
4The 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.
5To transmit again, press the PTT button.
OR
Press the programmed Emergency Off button to exit the Emergency mode.
6Press Emergency Off button to exit the Emergency mode.
If your radio is set to Silent, it does not display any audio or visual indicators during Emergency mode, or allow any received calls to sound through the radio’s speaker, until the programmed hot mic transmission period is over, and you press the PTT button.
If your radio is set to Silent with Voice, it does not display any audio or visual indicators during Emergency mode when you are making the call with hot mic, but allow sound through the radio’s speaker when the target radio responds after the programmed hot mic transmission period is over. The indicators only appear when you press the PTT button.
NOTE: If the Emergency Alarm request fails, the radio does not retry to send the request, and enters the hot mic state directly.
