DMO Calls
You can make and receive Group Calls when the MTH800
operates in Direct Mode (DMO). This includes Emergency Group
Calls.
The MTH800 returns to the Home display when there is no activity
for a few seconds.
Making Calls
See the relevant sections in the user guide.
Modifying the Type of Call
The infrastructure can modify the type of call you started.
For example, you might start a a half-duplex Private Call, and
the infrastructure could modify the call to a Group Call.
The terminal will alert you of the modification and will display
the following messages, depending on the type of call:
Call Modified (to full-duplex)
Call Modified Use PTT (modified to half-duplex)
Continue the modified call depending on the type of call.
Receiving Calls
The MTH800 will automatically receive the incoming call.
Additionally, if Inactivity Revert Mode is enabled, the
MTH800 returns automatically to the Home display, after
that call ends.
• Half-duplex Private Call modified from direct setup to hook setup:
a ringing tone will alert of the change.
• Half-duplex Private Call modified from hook setup to direct setup:
there will be no indication of the change.
Inactivity Revert Mode will occur if configured by your Service Provider.
