If your radio is set to Silent with Voice, it will not display any audio or visual indicators during Emergency mode, but allow incoming calls to sound through the radio’s speaker. The indicators will only appear once you press the PTT button to initiate, or respond to, the call.

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”.

If you press the PTT button during the programmed hot mic transmission period, 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 or the Emergency footswitch.

2The display shows Sending Alarm. The green LED lights up and the Emergency icon is displayed.

3Once the display shows Emergency Alarm Successful, 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.

4While transmitting, the green LED lights up and the Emergency icon appears on the display.

5Once the hot mic duration expires, the radio automatically stops transmitting. To transmit again, press the PTT button.

If your radio is set to Silent, it will 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 will 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 will 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.
