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).
3.5.2.2
Receiving Emergency Group Calls
The radio receives an Emergency Group Call from a selected pre-programmed group. An appropriate
tone, status icon, and red color of the display indicates an incoming call.
3.5.3
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
and changing talkgroup is not allowed.
In Trunked Mode Operation (TMO), it is possible to configure the radio to make Emergency Non-
Tactical Group Calls without sending attachment. If set, the radio assumes implicit attachment after
receiving a temporary address.
In Direct Mode Operation (DMO), the Non-Tactical Emergency proceeds on the same frequency as the
previously selected talkgroup. The service provider can designate any Individual TETRA Subscriber
Identity (ITSI) address to be used for Emergency Operations and this ITSI can be an Open Group -
broadcast address.
After exiting from Non-Tactical Emergency, the radio goes back to the previously selected talkgroup.
3.5.4
Emergency Individual Calls (Private or MSISDN)
The Emergency Individual Calls are simplex or duplex calls with emergency priority.
On pressing the
Emergency
button, the radio initiates an individual call to a provisioned private or
Mobile Station Integrated Services Digital Network (MSISDN) address.
This feature also supports the direct or hook dialing method on simplex and duplex calls. For full
duplex Emergency Individual Calls initiated to an MSISDN address, the default dialing method is
configured to hook and it cannot be modified.
During an emergency individual call, the radio rejects all incoming individual calls with non-emergency
priority. These rejected calls are shown as missed calls after the emergency individual call has ended.
3.5.5
Emergency SDS Status
The radio sends a status message with a preprogrammed value to the destination address set by your
service provider. Emergency SDS Status is available in TMO only. If no status acknowledgment or
negative acknowledgment is received, the radio retries sending the message. Status is not resent
when Emergency Alarm or Hot Microphone is configured.
