DO NOT DISTURB
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 will hear very long beeps, the same tone as if the system phone is ringing normally.
