Power Saving

The power-saving feature turns off the backlight and screen to conserve energy. The IP phone and UC46 (if connected) enter power-saving mode after the phone has been idle for a certain period of time. And the IP phone and UC46 (if connected) will exit power-saving mode if a phone/UC46 event occurs - for example, the phone receives an incoming call or a new message, or you press a key on the phone/UC46.

NOTE

If the Screen Saver is enabled on your phone, the power-saving mode will still occur. For example,if a screen saver is configured to display after the phone has been idle for 5 minutes, and the power-saving mode is configured to turn off the backlightand screen after the phone has been idle for 15 minutes, the backlight andscreen will be turned off after the screen saver displays for 10 minutes.

Power Saving Configuration

You can enable or disable power saving, and set the different idle timeout for office hours and off hours.

Office Hour: specify the start time and end time of the day’s office hour. You can change the office hours to avoid affecting your work.
Idle Timeout: specify the period of time before the IP phone enters the power-saving mode.

You can specify the following three types of idle timeout:

Office Hours Idle TimeOut: specify the idle timeout for office hours.
Off Hours Idle TimeOut: specify the idle timeout for non-office hours.
User Input Extension Idle TimeOut: specify the idle timeout that applies after you use the IP phone (for example, press a key on the phone or pick up/hang up the handset).

By default, the Office Hours Idle Timeout is much longer than the Off Hours Idle TimeOut. If you use the IP phone, the idle timeout that applies (User Input Extension Idle Timeout or Office Hours/Off Hours Idle TimeOut) is the timeout with the highest value.

If the phone has an incoming call or new message, the User Input Extension Idle TimeOut is ignored.

TIP

You can choose to set a higher User Input Extension Idle TimeOut than the Office Hours Idle TimeOut and Off Hours IdleTimeOut so that the phone does not enter the power-saving mode too often after you use the phone.

The following table lists the parameters you can use to configure power saving.
