General Settings
Power Saving
The power saving feature is used to turn off the backlight to conserve energy. The IP phone
enters power-saving mode after it has been idle for a certain period of time.
The IP phone will exit power-saving mode if one of the following phone events occurs:
 Tap any key.
 There is an incoming call.
 A new prompt (e.g., missed call, new voice mail or forwarded call).
You can configure the following power-saving settings:
 Office Hour
 Idle Timeout (minutes)
The office hour and idle timeout (minutes) settings work only if the power saving feature is
enabled.
Note
Power saving is configurable via web user interface only.
