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 are divided into folders. Each folder may contain 
several talkgroups.
For ease of use, your MTH800 also provides the ability to:
•   Perform an alphabetical search of the talkgroup aliases. 
Scroll through the entire talkgroup list.
•   Organise your favourite groups into one folder called My 
Groups (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 
 MTH800 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. 
When receiving a call, choose one of the following:
•   Exit selection screen to join the call. 
•   Join the call from the selection screen by pressing PTT.
•   Continue selection.
