A non-voice signal which triggers an alert indication on a group of ra-
dios.
Once the Emergency Alarm is acknowledged, the group of radios can
communicate over the programmed Emergency channel.

is automatically activated which is known as hot mic. Hot mic allows
you to communicate with the group of radios without pressing the PTT
button.

• If Emergency Cycle Mode is enabled, repetitions of hot
mic and receiving period are made for a programmed
duration.

ceiving period, you hear a prohibit tone, indicating that

the PTT button press and remains in Emergency mode.

retry to send the request, and enters the hot mic directly.
