Emergency Group Call; Making Emergency Group Calls; Receiving Emergency Group Calls - Motorola MTP850 Feature User Manual

Note: It is possible to turn on the radio by pressing the EMERGENCY button. Depending on the service
provider settings, the radio can start Emergency Operations automatically. If the radio is PIN-protected
(except for SIM PIN), Emergency Operations will bypass the PIN lock for the duration of the Emergency
Operations.
When starting Emergency Operations, any ongoing voice call is aborted or cleared down, and any packet data transfer
in progress is aborted. However, the session is kept open.
During Emergency Operations, the radio rejects phone, PABX, and private calls, and does not monitor the talkgroups
in the selected scan list.
To terminate Emergency Operations, press the rightSOFT key.

Emergency Group Call

The Emergency Group Call has the highest communication priority that means it is the pre-emptive kind of call.
Emergency Group Call is available in both TMO and DMO. During Emergency Operations, Emergency Group Call
can be started by pressing pressing the E
which allows the Emergency Call to be conducted without pressing the PTT button.
If the radio receives an incoming group call with emergency priority, the display shows that an emergency call has
been received, and a special audio alert is played.
An emergency group call can be configured as:
• A non-tactical call – initiated on a talkgroup preprogrammed by your service provider. When in non-tactical
emergency mode, you cannot switch talkgroups.
• A tactical call – initiated on the currently selected talkgroup.
In TMO, if the radio enters Emergency Operations while the Emergency Broadcast Call is active, the radio continues
on the call without initiating any calls and sends the Emergency Alarm.
When the Emergency Group Call you participate in terminates, your radio can behave in several ways, depending on
your service provider settings:
• If you are the call initiator, the radio can either stay in the Emergency Mode, or return to TMO.
• If you are not the call initiator, the radio always returns to TMO.
