DO NOT DISTURB
Use this feature to silence your telephone. When
you activate the do not disturb (DND) function,
you will not hear paging tones, voice paging, or
incoming call rings.
Instead, the LINE light flashes to signal an
incoming call. If you receive an intercom call, the
[INTERCOM] light flashes, and the number of the
incoming intercom call appears on the display.
1. Press
[DO NOT DISTURB] twice to prevent
interruptions. The DO NOT DISTURB light goes on
and the screen displays DND.
2. Press
[DO NOT DISTURB] again to resume
normal call alerts. The DO NOT DISTURB light
goes off and the screen no longer shows DND.
Callers hear very long beeps, the same tone as if
the system phone is ringing normally.
