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.

You can select a talkgroup in one of the following ways, by
using the:
• rotary knob
• navigation key
• alphabetical search feature
• folder search
• numeric keypad entry - Speed Dialing (if configured by
your Service Provider)
