Power Save and Power Save Plus
There are two levels of energy-saving modes that your system administrator can set up:
•
Power Save: Backlight turns off when not in use for a period of time, reducing the power requirements.
•
Power Save Plus: The phone display goes blank, turning the phone off and on at predetermined times.
The power to the phone is significantly reduced.
Power Save
Depending on how your system administrator set up your phone, the phone display may go into a power-save
mode (the backlight turns off).
Backlight can also be configured on or off manually from Applications button of the phone.
The Cisco IP Phone 7811 does not support backlight.Note
To turn on the phone display, press any button, or pick up the handset.
Power Save Plus
Your phone supports the Cisco EnergyWise (EW) program, also known as Power Save Plus. Your system
administrator sets up sleep (power down) and wake (power up) times for your phone to save energy. If your
phone goes into the Power Save Plus mode, the Select button is lit white.
The Cisco IP Phone 7811 does not support Power Save Plus.Note
Ten minutes before the scheduled sleep time, the Select button lights up and you receive a message that your
phone will power off at a specific time. If enabled by your system administrator, you also hear your ringtone
play. The ringtone plays according to the following schedule:
•
At 10 minutes before power off, the ringtone plays four times
•
At 7 minutes before power off, the ringtone plays four times
•
At 4 minutes before power off, the ringtone plays four times
•
At 30 seconds before power off, the ring tone plays 15 times or until the phone powers off
If your phone is inactive (idle) at the sleep time, you see a message to remind you that your phone is about
to power down. To keep the phone active, you need to press OK in the message or any key on the phone. If
you do not press the button or any key, your phone powers down.
