With the Firmware Release 12.0(7), the Office Hours feature is available on the Cisco IP Phone 8800 Series Multiplatform Phones. This feature helps to reduce power consumption during periods of inactivity. When the Office Hours feature is enabled, the phone enters the Display Off Mode and turns off the screen to save power outside of the designated working hours. The display will be turned on again if you press any key on the phone or if there are any incoming calls or voicemails. The display remains on until the phone has been in idle for a designated length of time, then it turns off automatically.

Meanwhile, when the phone screen is off, you can also control whether to light up the backlight of the Select button in the Navigation cluster.
