TMO Group Call
TMO Group Call 
General
A Group Call is an instant communication between you and 
others in a talkgroup that you select. Participants may join 
(late entry) and leave an on-going Group Call. A talkgroup is 
a pre-defined set of subscribers enabled to participate in and/
or invoke a Group Call, that is set up by your Service 
Provider. 
Talkgroups appear on your display as names or numbers (for 
example: Sales, Service, Electricians, Talkgrp10).
Talkgroups can be divided into three folders. Each folder 
may contain several talkgroups.
For ease of use, your MTM800 Enhanced also provides the 
ability to:
• Perform an alphabetical search of the talkgroup aliases. 
Scroll through the entire talkgroup list.
• Organise your favourite groups into  three  folders (default 
name for the first favorite folder is called My Groups which 
is set up by your Service Provider).
Your talkgroups may be organized into scan lists (set up by 
your Service Provider, or by yourself through the Menu). 
When you activate one of these scan lists, your MTM800 
Enhanced will continuously monitor the activities of the 
selected talkgroups.
By assigning priorities to the talkgroups defined in the scan 
list, you will be capable of accepting calls that have higher 
priority than the on-going call.
You can start talkgroup, folder, or scanning selection when 
the terminal is idle or receiving a call. 
While being in a call and dialling another group 
simultaneously, do the following to talk in the current call:
