English
Hot Microphone Feature (TMO Only)
If the Hot Microphone feature was programmed into your MTH800
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 MTH800 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.
Making an Emergency Group Call
To initiate or answer a call while in Emergency Mode:
• Press and hold PTT.
• Wait for the talk permit tone (if configured) and talk.
• Release PTT to listen.
Some systems do not support the Emergency Alarm feature when the user
is in a “Local Area Service” area.
Pressing the Emergency button, even if Transmit Inhibit is activated, causes
the MTH
800 to transmit immediately. The MTH800 must NOT be within the
RF sensitive area when entering Emergency Mode
