Power Save and Power Save Plus
There are two levels of energy-saving modes that your system administrator can set up:
• Power Save—The phone display goes blank 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 phone screen appears blank and the Select button is lit white).
To turn on the phone display, press any button, touch the blank phone screen, or pick up the handset.
Power Save Plus
Your Cisco IP 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.
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.
If your phone is active (for example, on a call), your phone waits until it has been inactive for a period of time
before telling you of the pending power shutdown. Before the shutdown happens, you see a message to remind
you that your phone is about to power off.
After your phone goes to sleep, press Select to wake up your phone. After the phone is inactive for a period
of time, a message displays to alert you that the phone is about to power down. At the configured wake time,
your phone powers up.
