Ambience Listening (Al); Cancelling An Incoming Call; Covert Mode - Motorola TETRA MTM800 Manual

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 28. For changing range
during a broadcast call see "Changing a Talkgroup during/on
receiving a call" on page 31.

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
forwarded to the Missed Call list.

Covert Mode

If configured by your Service Provider the Covert Mode gives
to you the ability to completely shut down all visible and
audible MTM800 alerts and notifications. This feature makes
the MTM800 effectively unnoticeable even in a silent and
dark environment.
