TMO Group Calls
In TMO the MTP850 is used with your Service Provider's
infrastructure.
Making a TMO Group Call
1. From the Home display and if this is the required group, press
and hold the PTT.
2. Wait for the talk permit tone and then speak into the microphone.
Release the PTT button to listen.
When you start a call, all members of the selected group who have
their units turned on, will receive the Group Call.
The No Group message is displayed when you are out of the
normal coverage area of your selected group. You must then select
a new group that is valid for your working location.
If you are in an on-going Group Call and wish to make a new call,

Receiving a TMO Group Call
Unless it is engaged in a call, your MTP850 will receive the Group
Call. To answer the call, press and hold PTT.
Your MTP850 shows the group name and the caller's private
number or alias if previously stored in your contact list.
Receiving a TMO Broadcast Call
The Broadcast Call (also called Site Wide Call) is a high-priority
Group Call from the console operator (or dispatcher) to all users.
The MTP850s are configured to monitor a Broadcast Call, but users
cannot talk back.
The Broadcast Call pre-empts an on-going Group Call that has the
same (or lower) call priority.
DMO Group Calls
In DMO the MTP850 can be used without your Service Provider's
infrastructure. DMO allows communication with other terminals also
operating in DMO, which are on the same frequency and group as
your MTP850.
