Muting/Unmuting the Microphone
During a Phone, PABX, or Duplex Private Call, use the mute
feature to:
• hold conversation without being heard by the caller
• silence possible background noise in your area
1. Press Mute. The display shows Mute is On. The
microphone is muted. You can hear the incoming audio, but
the caller cannot hear any speech coming from your
MTM800E.
2. To speak, press
Unmute. The display shows Mute is Off.
The microphone is on.
Covert Mode
If configured by your Service Provider the Covert Mode gives
to you the ability completely shut down all visible and audible
MTM800E alerts and notifications. This feature makes the
MTM800E effectively unnoticeable even in a silent and dark
environment.
To Enter the Covert Mode:
• Press the Cover Mode one-touch button (if programmed
by your Service Provider).
• Select Covert Mode in the Security menu (refer to Covert
Mode” on page 119.).
Local Area Service
This mode, also called Fallback Mode, allows more than one
terminal from the same site to communicate when the link
between the site and network central controller fails.
Entering and exiting Local Area Service (that is, returning to
System Wide Services) is done automatically.
This mode can be disabled by your Service Provider.
