dispatch systems to highlight emergency calls.
Some systems do not support the Emergency Alarm feature when
the user is in a "Local Area Service" area.

Hot Microphone Feature

If the Hot Microphone feature was programmed into your MTP850
by your Service Provider, you can make an Emergency Group Call
and talk to the dispatcher (and members of your group) without the
need to press and hold the PTT.
The microphone will stay open for a time period (programmed by
your Service Provider). The microphone will stay open until:
• the Hot microphone time period expires
• you press PTT during the Hot Microphone period
• you press the End key
At the end of the Hot Microphone the Emgcy Mic Ended message
will be displayed and the MTP850 returns to the Emergency Mode.
The Hot Microphone feature is disabled and PTT operation returns
to normal.
If required you can resume Hot Microphone by pressing the
Emergency button again.
Hot Microphone feature is available in DMO and TMO mode.
