User Manual

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.
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.
NOTICE: 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.
