DMO Private Priority Call
The service provider may assign Pre-emptive Priority to outgoing DMO Private Calls. If this is the case,
DMO Private Calls from this radio preempt any ongoing calls (with the exception of emergency calls or
ongoing Pre-emptive Priority Private Calls) on the receiving radio, which then displays Call-
preempted.
Talkgroup for Individual Calls
Talkgroup for Individual Calls is a talkgroup that operates on a separate frequency allocated for
individual (private) calls only. Using this talkgroup optimizes frequency resources and helps not to
block other talkgroups. The only supported call types are: private calls and emergency calls (both
private and group). Use this talkgroup each time you need to make a private call.
When you select a Talkgroup for Individual Calls, your radio is not able to receive or initiate any group
or broadcast calls with priority lower than Emergency.
When you have selected a Talkgroup for Individual Calls and press the PTT button to start a Group
Call, the radio:
• Rejects the call
• Plays a tone
• Displays the Individual Calls Only message
Communication through Repeaters
Radios that are out of range and cannot communicate directly one with another in DMO Mode can do it
through the repeater. The repeater is a radio that repeats all communication on a chosen channel, and
as a result increases radios’ DMO range.
DMODMO
When the radio connects to a repeater, it plays a tone, displays the Repeater available message, and
shows an appropriate icon. When the radio looses connection with the repeater, it plays a tone,
displays the Repeater not available message, and the repeater icon is blinking.
Communication through Gateways
Gateway provides connectivity between radios operating in DMO Mode and the TETRA network, so
that the DMO radios can communicate with the TMO radios.
