sites. The terminals are configured to monitor a Broadcast
Call, but the users cannot talk back.
The call can be received as normal
broadcast call or emergency broadcast
Call.
The Broadcast Call pre-empts an on-going
Group Call that has the same (or lower) call priority.
For selecting a talkgroup during a broadcast call, see
“Selecting a Talkgroup” on page 30. For changing range
during a broadcast call see “Changing a Talkgroup during/on
receiving a call” on page 34.
Ambience Listening (AL)
This feature, if enabled by your Service Provider, allows a
console operator or dispatcher to establish a special call with
a specific MTM800 to monitor voice activity in the local
vicinity. The call is setup without any indication to the affected
MTM800, and any lower priority ongoing voice call or packet
data transfer may be pre-empted.
After accepting the call, the MTM800 transmits in a half-
duplex Private call without any action from or indication to the
user. The Ambience Listening call shall automatically end
when the user initiates any voice call and uses the terminal
normally.
Cancelling an Incoming Call
In all modes (except Group), if you wish to cancel a call
during an active call, press Reject. The call number will be
forwarded to the Missed Call list.
