Power Saving
The power-saving feature is used to turn off the backlight and screen (turning off the screen is
only applicable to SIP-T48G/T48S/T46G/T46S/T29G IP phones) to conserve energy. The IP
phone enter power-saving mode after the phone 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
(touch screen is only applicable to SIP-T48G/S IP phones). The power saving is not applicable to
SIP-T19(P) E2 IP phones.
If the screen saver (refer to Screen Saver) is enabled on your phone, power-saving mode will still
occur. For example, if a screen saver is configured to display after the phone is idle for 5 minutes,
and power-saving mode is configured to turn off the backlight and screen after the phone is idle
for 15 minutes, the backlight and screen will be turned off after the screen saver displays for 10
minutes.
You can configure the following power-saving settings:
Office Hour: Configures the starting time and ending time of the day’s office hour for each
day of the week. You can configure power saving around your work schedule.
Idle TimeOut (minutes): Configures the period of time before the IP phone enters
power-saving mode. You can configure different idle timeouts for office hours and off
hours (evenings and weekends). You can also specify a separate timeout period that
applies after you use the phone.
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 message, the User Input Extension Idle TimeOut is ignored.
Note
If you disable the power saving feature, the IP phone will automatically enter power-saving mode
to protect the screen when the phone is inactive for 72 hours. That is, the color screen phones will
turn off the backlight and screen, and the black-and-white screen phones will only turn off the
backlight.
