With the Night mode feature, the users can dim the light of the phone screen to minimum. Use the Settings file or the phone web interface to enable and disable the Night mode feature. When you enable the feature, the phone idle screen, Login screen, and the Brightness settings screen displays the Night mode menu option. Additionally, you can configure the Night mode soft key for an idle call appearance line.

When the user activates the Night mode feature, the phone switches off the Beacon LED, the Missed call LED, and the Red LED on the line keys. The phone continues to display the green LED on the line keys for the other active features.

The Night mode feature does not affect the illumination of the Speaker, Mute, and Headset buttons.

Only Avaya J179 IP Phone supports this feature.
