All the above operations are performed by transmitting data to your radio.
3.1.6.1
DGNA Reception
When a DGNA message is received, your radio plays a tone and displays a message Talkgroup
list updated.
When your service provider deletes (de-assigns) the currently selected talkgroup, depending on the
settings, your radio can perform one of the following actions:
• Enter the “No Group” state – your radio does not attach to any talkgroup automatically.
• Attach to the last selected TMO talkgroup. If the last selected TMO talkgroup is not available (it was
deleted), your radio enters the “No Group” state.
• Attach to a default talkgroup configured by your service provider. If the default talkgroup is not
available (it was deleted), your radio enters the “No Group” state.
At each talkgroup change, an appropriate notification is shown on the display.
If the DGNA message is received to delete all talkgroups, your radio displays All Talkgroups
Deleted.
3.1.6.2
DGNA Auto Select Group
If the DGNA Auto Select is configured, whenever your radio receives a DGNA, it switches to the added
talkgroup.
3.1.6.3
DGNA Auto Reselect Group
DGNA Auto Reselect allows your radio to return to the previous selected talkgroup. Your network
operator assigns a talkgroup to your radio through DGNA. When the assigned talkgroup is deassigned,
your radio automatically returns to the previous talkgroup.
3.1.7
Broadcast Call
Broadcast Group Call (also called Site Wide Call) is a high-priority group call from the console operator
(or dispatcher) to all users located at one or more sites. The radios are configured to monitor a
Broadcast Call, but you cannot talk back. The call can be received as a normal Broadcast Call or an
Emergency Broadcast Call. The Broadcast Call preempts an ongoing Group Call that has the same or
lower call priority.
NOTE: Your radio is only able to receive Broadcast Calls.
