Changing talkgroups in Gateway mode
When a talkgroup is changed in Gateway mode, only the DMO talkgroup changes; the TMO
talkgroup remains unchanged unless the radio has been configured with fixed pairs of DMO and
TMO talkgroups. (The radio can be programmed with up to 100 pre-set pairs of TMO and DMO
talkgroups.) In this case, if the selected DMO talkgroup is paired with a TMO talkgroup then the radio
also automatically selects the paired TMO talkgroup.

Repeater Mode
A radio acting as a repeater provides a service to other radio users. It extends the range and
enhances the reliability of Direct Mode communication compared with basic direct communication
between radios.
You can use a repeater to enable communication between radios which are out of range of each
other. The following diagram shows radios A, B and C and a repeater which are on the same DMO
talkgroup. A, B and C are in range of the repeater. Because of its location, the repeater can pass
communications between A, B and C even though they are out of range of each other.
