Emergency Operation
• If you press the Emergency button while the MTM800 
Enhanced is in Emergency Mode.
• If you change group while in Emergency Mode.
The screen will show one of the following delivery reports:
• Alarm Sent
• Alarm Failed
In both cases, the screen 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.
OR - if configured by your Service Provider - your MTM800 
Enhanced will send an Emergency Alarm:
• If you press the Emergency button without entering 
Emergency Mode before. 
> Other Emergency services such as starting TMO 
Emergency Mode or initiating Emergency Private Call 
will be unavailable. 
> No visible and audio indication on sending 
Emergency Alarm will be done. 
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.
For the delivery reports, see “Sending an Emergency Alarm” 
above.
Some systems do not support the Emergency Alarm feature 
when the user is in a “Local Area Service” area (see page 30).
While in an Emergency Group Call, you can still perform group 
operations (such as changing group/folder, searching for a 
group, or entering the My Groups folder).
