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.

When you start a call, the members of the selected group who have

their units turned on will receive the Group Call.

In DMO the MTP850 can communicate with the trunking system

(and vice-versa) if the Gateway option is enabled in the MTP850.

Making a DMO Group Call

1. Enter Direct Mode by pressing Optns and selecting Direct

Mode.

2. Make sure that you have selected the required group. Press and

hold the PTT button.

3. Wait for the talk permit tone and then speak into the microphone.

Release the PTT button to listen.

Receiving a DMO Group Call

You can receive a DMO Group Call only when your MTP850 is in

DMO.

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.

Exiting DMO

To exit DMO, press Optns and select Trunked Mode.

In DMO you can only place Group Calls and Emergency Group Calls.
