3.4.7 Private Call With Presence Check

This feature allows you to see if the calling party is available in DMO. When this feature is enabled, you can
only initiate a Private Call if the called radio is present on the same channel and responds with a presence check
acknowledgement.
Otherwise your radio displays Party not available.

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 message

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.
