Sending An Emergency Call With Hot Mic (Trunking Only)
This feature allows you to send an Emergency Call with hot mic to a group of radios.
When and where to use:
Your radio must be programmed for this type of operation.
Your radio 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. The hot
mic applies to the first voice transmission from your radio during the Emergency call. For subsequent
transmissions in the same Emergency call, you must press the PTT button.
Follow the procedure to send Emergency Call with hot mic on your radio.
Procedure:
1 Press the preprogrammed Emergency button.
One of the following scenarios occurs:
• The display shows EMERGENCY on the current zone and channel. A tone sounds and the
LED blinks red momentarily.
• A tone sounds to indicate that the selected channel does not support emergency and rejects
to launch emergency mode.
2 Hold the radio vertically 1 to 2 inches (2.5 to 5.0 cm) from your mouth.
3 The microphone remains active for the hot mic time specified in the radio's codeplug
programming.

Sending an Emergency Alarm with Emergency Call
When and where to use:

indicating that the trunked system central controller has received the alarm. A dispatcher
acknowledgment (four high-pitched tones) follows, accompanied by an ACK RECEIVED display.

3 Press and hold the PTT button. Speak clearly into the microphone.

second.
