Cleaning the Cisco Unified IP Phone

To clean your Cisco Unified 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.
