Why does my phone not work ("wake up"), when it worked
If your system administrator has set up your phone for
EnergyWise, the phone may be sleeping (powered down). Your system administrator
sets your phone to sleep at a certain time and wake (power up) at a certain
time. Your phone will wake up at the time set by your system administrator. You
can press the Select button to wake your phone up. See your system
administrator to have the sleep and wake up times changed.
My phone played the ringtone four times in succession, but there
is no call. What does this mean?
The phone is notifying you that your phone will power down
(sleep) soon to conserve energy (the EnergyWise feature). Your system
administrator sets your phone to sleep at a certain time and wake (power up) at
a certain time. Your phone will wake up at the time set by your system
administrator. See your system administrator to have the sleep and wake up

Cleaning Cisco Unified IP Phone
To clean your Cisco Unified IP Phone, use only a dry soft cloth to gently wipe the phone and the phone screen. Do not apply liquids or powders directly on the phone. As with all non-weather-proof electronics, liquids and powders can damage the components and cause failures.
When the phone is in sleep mode, the touchscreen is blank and the Select button is not lit. When the phone is in this condition, you can clean the screen, as long as you know that the phone will remain asleep until after you finish cleaning. If the phone is likely to wake up during cleaning, wake it up or wait until it is awake before following the preceding cleaning instructions.
