Emergency Mode
You can send and receive Emergency Group Calls in Trunked 
Mode or in Direct Mode. If your terminal is configured to operate 
through a gateway, Emergency calls can be placed through the 
gateway.
You can initiate an Emergency Group Call to and receive it from the 
selected group (TMO and DMO).
Your Service Provider will configure the Emergency Alarm and Hot 
Microphone features.
Emergency calls will be allocated emergency priority in the system. 
Entering or Exiting Emergency Mode
To enter Emergency Mode, press and hold the Emergency button 
at the top of the MTH800. 
 
To exit Emergency Mode, press and hold Exit. Your terminal will 
switch to the Home display.
Sending an Emergency Alarm (TMO Only)
Your MTH800 will automatically send an Emergency Alarm when in 
Emergency Mode. This is sent:
• automatically, upon entering Emergency Mode
• if you press the Emergency button again while the MTH800 is in 
Emergency Mode.
After sending the alarm, the display will show one of the following 
delivery reports:
•Alarm Sent
• Alarm Failed
In both cases the display returns within a few seconds to the main 
screen of the Emergency Mode.
 
The required time you need to press the Emergency button is set to default 
to 0.5 seconds. The time can be configured by your Service Provider.
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.
