3.4.8 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
Individual Only

3.4.9 Communication through Repeater
Radios that 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.

When the radio connects to a repeater, it plays a tone and displays the
Repeater available
message. When the radio
looses connection with the repeater, it plays a tone and displays the
Repeater not available
message. Messages and
sounds are configured by the service provider.
3.4.10 Communication through Gateway
Gateway provides connectivity between radios operating in DMO Mode and the TETRA network, so that the
DMO radios can communicate with the TMO radios.
