Q
DMO group call
In DMO, the TGR990 can be used without your Service Provider’s
infrastructure. Direct Mode (DMO) allows communication with other
terminals also operating in Direct Mode, which are on the same
frequency and talkgroup as your TGR990.
You can receive a call:
•
From the selected talkgroup
•
From other users within talkback range (if configured by your
Service Provider). This is called an InterMNI (Mobile Network
identity) call.
•
From an open group. (An open group is a super-group to which
all DMO groups belong.)
When you start a call, the members of the selected talkgroup who
have their units turned on, and are within the group subscriber
identity (as configured by the Service Provider), will receive the
transmission.
If Transmit Inhibit is activated while the terminal is set to DMO, the
PTT
is disabled. You can only listen. For detailed information on
Transmit Inhibit, see Transmit Inhibit on page 31. DMO Talkgroup
selection is allowed when Transmit Inhibit is activated.
Q

Groups.
