Caution
This product is not a medical device and uses an unlicensed frequency band that is susceptible to
interference from other devices or equipment.
The Cisco Unified Wireless IP Phone 7921G has many of the same phone features as the IP phone
desktop models, such as Mute, access to voice messaging, and directories. The phone has a limited
number of buttons, because of its size. As a consequence, the following are some differences in its
operation:
•
No line buttons—You must enter the phone number from the key pad and press Send. You can press
the Phone icon from the main screen to use other lines on your phone.
•
Only two softkeys—You must press the Options softkey to see the list of softkey features.
•
You do not hear a dial tone.

How to Care for and Clean the Phone
Users need to know how to protect and clean their phone. These guidelines provide information about
using accessories and cleaning the 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.
•
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.
