2. Press PTT and start talking.
Pressing PTT on selection screen switches to a new group 
and starts a call.
Each talkgroup may have one associated Announcement 
Talkgroup (ATG) that it monitors (if set up by your Service 
Provider).
An ATG is a special group which is linked to a number of 
talkgroups and has the highest priority level, thus enabling 
broadcast of the call to all these talkgroups.
When an ATG is selected, the scanning icon is not displayed. 
The MTM800 Enhanced monitors the ATG scan list instead 
of the selected scan list. The ATG scan list contains all the 
talkgroups associated with a selected ATG. Your Service 
Provider should advise what talkgroups are associated with 
which Announcement Talkgroup.
Your MTM800 Enhanced will always monitor the Group Calls 
in the ATG scan list. To place an Announcement Call, you 
must first select the specified Announcement Talkgroup as 
advised by your Service Provider, otherwise you will only be 
able to participate when an Announcement Talkgroup is 
received.
Activation and deactivation of talkgroup scanning has no 
effect on the ATG scan list.
