These 32 SmartLabel keys  – four each on the left and right side of the display – control the SmartLabels

They can be programmed and labeled on the phone and on the Function Keys page of the phone's web interface. Four different functions for each key can be set on four "pages."

The factory default setting is line, except for keys P5–P8 which are preprogrammed with the following functions:

Do Not Disturb

Turn "do not disturb" (DND) mode on and off for all identities registered on the phone (Fig. 1). If you want to turn on DND for one or more, but not all of the identities (Fig. 2), use the Configuration identity settings on the phone's web user interface. In DND mode incoming calls do not ring; callers hear the busy signal.

Exception: Phone numbers on your directory's VIP list.

When DND is on, you'll see the DND symbol on the display.

Missed Calls

Displays a list of missed calls and simultaneously turns off the missed call LED.
DialedList of dialed calls for redialing, last-dialed call at the top of the list.
Next PageDisplays the next page of SmartKeys (cycles through page 1 to 4).
