Guidelines for Using Accessories and the Phone

Follow these guidelines when using accessories and your Cisco Unified Wireless IP Phone 7921G:

•Use only chargers, batteries, and accessories that are approved by the Cisco Unified Wireless IP Phone 7921G manufacturer. Use of unapproved chargers, batteries, and accessories might be dangerous, and will invalidate the warranty on your phone.

•Do not adhere a clip to the back of the phone or insert a clip between the phone and battery cover because it can damage the battery.

•Use a protective cover case to shield the phone from moisture, dust, hair, grease, and other contaminants that might get on your hands. For example, in Healthcare environments, where phones must be cleaned with sterilizing wipes, you must use a protective cover case to prevent moisture damage to the phone.

•Use a protective cover case in environments where the phone might be bumped or dropped, such as manufacturing or warehouse environments.

•When disconnecting the power cord of any accessory, grasp and pull the plug. Do not pull the cord.

•Keep accessories out of reach of young children.

•Clean the phone only with a soft dry cloth. Do not use moist wipes or cleaning powders that might damage the phone.

Note Using unapproved accessories, not protecting the phone from moisture, contaminants, and hard impacts can invalidate the one-year hardware warranty on the phone.
