Cleaning the Cisco Unified IP Phone
To clean your CiscoUnified IP phone, use a soft, dry cloth to wipe the phone and
the touchscreen. 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.
Disable the touchscreen before cleaning it so that you will not inadvertently
choose a feature from the pressure of the cleaning cloth. To disable the
touchscreen so that it will not respond to touch, press the Display button for more
than one second. The phone displays Touchscreen Disabled and the Display
button flashes green.
After one minute, the touchscreen automatically re-enables itself. To re-enable
the touchscreen before that, press the flashing Display button for more than one
second. The phone displays Touchscreen Enabled.
