Making Emergency Group Calls

Prerequisites: Ensure that your radio is in Emergency Mode.
Procedure:
1 Press and hold the PTT button.
2 Wait for the talk permit tone (if configured) and talk.
3 Release the PTT button to listen.
Note: It is possible to cancel making an emergency group call in TMO. To do this, perform one of the
following actions before the talk permit is granted (depending on your service provider settings):
• Release the PTT button.
• Press the END key (default).
When the call is canceled, your radio displays Call Cancelled message (if configured by your service
provider).

Receiving Emergency Group Calls

The radio receives an Emergency Group Call from a selected pre-programmed group. An incoming call is indicated
by an appropriate tone, status icon, and red color of the display.

Non-Tactical Emergency

In Non-Tactical Emergency, the radio switches to a designated Emergency talkgroup when starting Emergency
Operations. This talkgroup is used for the complete duration of the Emergency Operations (you cannot change the
talkgroup).
In TMO, it is possible to configure the radio to make Emergency Non-Tactical Group Calls without sending
attachment. If this is set, the radio assumes implicit attachment after receiving a temporary address.
In DMO, the Non-Tactical Emergency proceeds on the same frequency as the previously selected talkgroup. The
service provider can designate any ITSI address to be used for Emergency Operations, (this can be an Open Group –
broadcast address).
After exiting from Non-Tactical Emergency, the radio goes back to the previously selected talkgroup.

Emergency Individual Calls (Private or MS-ISDN)

The Emergency Individual Calls are Simplex or Duplex Calls with emergency priority. On pressing the
EMERGENCY button, the radio initiates an Individual Call to the provisioned address (private or MS-ISDN). During
this kind of call all user indications are unavailable and all other services are rejected. Emergency Operation ends as
soon as the Emergency Individual Call is ended.

Emergency Alarm

The Emergency Alarm is a special status message sent to the infrastructure while starting the Emergency Operations.
The radio can wait for infrastructure acknowledgment for this alarm and attempts retries.
Each time the radio enters the Emergency Operation, it sends the Emergency Alarm. When the Emergency Alarm is
sent successfully, the respective audible tone sounds.
In addition, once the radio is in the Emergency Operation on pressing the E
alarm is sent (exception: during Hot Microphone transmission).
The message can be dispatched both in TMO and DMO.
