Receiving a DMO Group Call
You can receive a DMO Group Call only when your MTM800 
is in DMO.
Your MTM800 will display the caller’s private number or alias 
and the talkgroup name.
The following screens show examples of how the caller’s 
identity can be displayed.  
Receiving a DMO Group Call (MS – MS)
If Gateway and Repeater mode is selected, and if one of the 
devices is not available, the call setup is proceeding as if this 
device was not selected. 
Example
: In case of the Gateway is available and the Repeater 
is not available, after an unsuccessful Gateway call attempt the 
call falls back to MS – MS mode immediately with the MS – MS 
call message.
For call alert, see settings in the Tones menu option (page 88).
