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 Direct Mode
Operation (DMO) 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.

Figure 4: Communication through Repeaters

When the radio connects to a repeater, it plays a tone, displays the Repeater available message,
and shows an appropriate icon. When the radio loses 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 Direct Mode Operation (DMO) and the
TETRA network, so that the DMO radios can communicate with the Trunked Mode Operation (TMO)
radios.
