You can activate or deactivate the DND mode on a per-line basis. If DND mode is activated for a specific line, all incoming calls to the line will be rejected automatically, and the callers will hear a busy signal.
To activate DND mode for a specific line:
1. Press to enter the main menu.
2. Select ->Do Not Disturb.
The LCD screen displays the incoming lines currently assigned to the handset.
3. Press or to highlight the desired line, and press the OK soft key.
4. Press or to select Enabled from the Status field.
5. Press the OK soft key to accept the change.
The icon on the idle screen indicates the DND mode is activated. You can press the Line soft key when the handset is idle to check the line status. The icon in the bottom of a line indicates that the DND mode is activated for this line.
The handset will reject all incoming calls to the line, and the LCD screen displays the missed call icon followed by the number of missed calls.
