If your radio is set to Silent with Voice, it does not display any audio or visual indicators during Emergency mode, but allow incoming calls to sound through the radio’s speaker. The indicators 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 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.
