• From an open group. (An open group is a super-group to
which all DMO groups belong.)
Emergency calls can be placed via gateway and repeater.
For gateway and repeater settings, see "Gateway/Repeater
Selection" on page 49.
Hot Microphone Feature in DMO
This functionality allows the user, that is in emergency
situation, to be heard without pressing the PTT. It needs to be
enabled by your Service Provider for DMO mode. For the
detailed functionality please see Hot Microphone Feature in
TMO.
When the radio is in emergency mode and it switches from
TMO to DMO (and vice versa), the Hot Mic feature is still active.
Changing Folder or Group
Proceed as explained in the Group Call section, "TMO Group
Call" on page 35.
Making an Emergency Group Call
To initiate or answer a call:
1. Enter Emergency Mode by pressing the Emergency
button.
2. Press and hold PTT.
3. Wait for the talk permit tone (if configured) and talk.
4. Release PTT to listen.
Your MTM800E enters TMO by pressing the Emergency
button (if configured by your Service Provider). The terminal
attaches to the predefined talkgroup and starts the Emergency
Group Call. If the predefined talkgroup is invalid the terminal
attaches to the last selected talkgroup.
