Chapter 9 Troubleshooting and Maintenance Cleaning the Cisco Unified IP Phone http://www.cisco.com/en/US/products/sw/voicesw/tsd_products_support_ category_home.html 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. OL-14640-01 Cisco Unified IP Phone 7975G Administration Guide for Cisco Unified Communications Manager 6.1 9-19

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.
