To configure the screen saver wait time via web user interface:
1. Click on Settings->Preference.
2. Select the desired wait time from the pull-down list of Screensaver Wait Time.
3. Click Confirm to accept the change.
The power saving feature is used to turn off the screen to conserve energy. The IP phone
enters power-saving mode after it has been idle for a certain period of time. And the IP
phone will exit power-saving mode if a phone event occurs—for example, if the phone
has an incoming call or message, or you press a key on the phone or tap the touch
screen (only applicable to SIP-T48G). If the screen saver is enabled on your phone,
power-saving mode will still occur. The power saving is only applicable to SIP-T48G,
SIP-T46G and SIP-T29G IP phones.
You can configure the following power-saving settings:
Office Hour: Configures the starting time and duration of the day's office hour each

day using configuration files (or configures the starting and ending time of office
hour each day via web user interface).
Idle Timeout (minutes): Configures the period of time before the IP phone enters

power-saving mode.
