Understanding Feature Availability
The operation of your Cisco Unified Wireless IP Phone 7921G and the features available to you may
vary, depending on the call processing agent used by your company and also on how your company’s
phone support team has configured your phone system. Therefore, some of the features included in
this guide might not be available to you or might work differently on your phone system. Contact your
support desk or system administrator for information about feature operation or availability.
Cleaning the Phone
Gently wipe the phone screen and phone with a soft, dry cloth. Do not use any liquids or powders on
the phone. Using anything other than a soft, dry cloth can contaminate phone components and cause
failures.
Note If you need to clean or disinfect your phone, you can purchase a silicon cover for your
Cisco Unified Wireless IP Phone 7921G. For more information, refer to the Cisco Unified
Wireless IP Phone 7921G Accessory Guide.
