Sending an Emergency Alarm with Voice to Follow
This feature allows you to send an Emergency Alarm to another
radio. Upon acknowledgment, your radio’s microphone is
automatically activated, allowing you to communicate with the
other radio 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:
1 Press the programmed Emergency button or the
Emergency footswitch.
2 The display shows Sending Alarm. The green LED lights
up and the Emergency icon is displayed.
3 Once 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.
4 While transmitting, the green LED lights up and the
Emergency icon appears on the display.
5 Once the hot mic duration expires, the radio automatically
stops transmitting. To transmit again, press the PTT button.
