Selecting TMO and DMO
In Direct Mode Operation (DMO), radios communicate directly with other
TETRA radios without using a network. Coverage depends on the
position of the caller and the receiving radio. When you switch to DMO
mode your radio leaves the network and tunes to the selected DMO
talkgroup. In Trunked Mode Operation (TMO) your radio operates on the
network infrastructure supplied by your service provider.
To change operating mode from the Home screen
Press the Menu context key, then select Networks > Operating Mode.
Scroll to the mode (highlight it) and press Select.
Selecting a talkgroup
Your radio is customised with talkgroups that typically include users
who are either performing a similar role or who are within a distinct
location or provide a service that you use.
The way you select a talkgroup depends on the customisation of your
radio. Your radio may be customised for Folder Selection Mode or Talkgroup
Selection Mode. Contact your service provider for information about the
customisation of your radio.
Talkgroup Selection Mode
If your radio is customised for Talkgroup Selection Mode, you need to
select a talkgroup before you can make a call. You can change the
talkgroup at any time.
To select a talkgroup:
1. From the Home Screen, press the Groups key. The current selected
folder and talkgroup appear in the talkgroup selection box.
