Hot Microphone Feature - Motorola MTP850 Basic User's Manual

In both cases, the display returns within a few seconds to the main
screen of the Emergency Mode.
Due to no delivery confirmation in DMO, Alarm Sent information
confirms only sending the alarm.
The Emergency Alarm is a special status message sent to the
dispatcher monitoring the selected group. This can be used in
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.

Pressing the Emergency button, even if Transmit
Inhibit is activated, causes the MTP850 to trans-
mit immediately. The MTP850 must NOT be
within the RF sensitive area when entering Emer-
gency Mode.
