TMO Group Call
Using the Navigation Key
Your Service Provider configures the 
MTM800 to display only selectable 
talkgroups. Press the navigation key to 
scroll to the required talkgroup and press 
Ok. For talkgroup range scrolling configuration, see note in 
“Selecting a Range” below.
Using Alphabetical Search
1. In Group Mode, press 
Optns.
2. Select 
abc for talkgroup alpha search.
3. You are now at the talkgroup alpha 
search screen. Enter an alphanumeric 
digit, and the MTM800 starts searching 
for the first Talkgroup alias, that starts 
with that character. Use the navigation key to scroll to 
adjacent aliases. In this example “a” is entered.
4. Select the desired talkgroup by pressing 
Ok, or press PTT to select and start a call 
on the new group.
Using the Numeric Keypad
When the terminal is in group mode and not transmitting (i.e., 
idle or receiving a call), you can dial a group by entering its 
speed number via the keypad. This feature is called 
Talkgroup Speed Dialling. The speed number is pre-
configured in the terminal.
You can also view a speed number attributed to a group, if it 
exists.
