Safety and Performance Information
Read the following safety notices before installing or using your wireless IP phone.
Warning IMPORTANT SAFETY INSTRUCTIONS
This warning symbol means danger. You are in a situation that could cause bodily injury.
Before you work on any equipment, be aware of the hazards involved with electrical
circuitry and be familiar with standard practices for preventing accidents. Use the
statement number provided at the end of each warning to locate its translation in the
translated safety warnings that accompanied this device.
Statement 1071
SAVE THESE INSTRUCTIONS

Getting Started
Cisco Unified Wireless IP Phone 7921G for Cisco Unified CallManager 4.1, 4.2, 5.0 and Later 3
Warning The plug-socket combination on the battery charger must be accessible at all times
because it serves as the main disconnecting device. Statement 1019
Warning The battery charger requires short-circuit (overcurrent) protection to be provided as part
of the building installation. Install only in accordance with national and local wiring
regulations. Statement 1045
Warning Do not use the Cisco Unified Wireless IP Phone 7921G in hazardous environments such
as areas where high levels of explosive gas may be present. Check with the site safety
engineer before using any type of wireless device in such an area.
Warning Telephone receivers produce a magnetic field that can attract small magnetic objects
such as pins and staples. To avoid the possibility of injury, do not place the handset
where such objects may be picked up.
Battery Safety Notices
These battery safety notices apply to the batteries that are approved by the Cisco Unified Wireless IP
Phone 7921G manufacturer.
Warning There is the danger of explosion if the battery is replaced incorrectly. Replace the battery
only with the same or equivalent type recommended by the manufacturer. Dispose of
used batteries according to the manufacturer’s instructions. Statement 1015
Warning Ultimate disposal of this product should be handled according to all national laws and
regulations. Statement 1040
Warning Do not dispose of the battery pack in fire or water. The battery may explode if placed in
a fire.
Caution The battery pack is intended for use only with this device.

4OL-10806-02
Caution Do not disassemble, crush, puncture, or incinerate the battery pack.
Caution To avoid risk of fire, burns, or damage to your battery pack, do not allow a metal object
to touch the battery contacts.
Caution Handle a damaged or leaking battery with extreme care. If you come in contact with the
electrolyte, wash the exposed area with soap and water. If the electrolyte has come in
contact with the eye, flush the eye with water for 15 minutes and seek medical attention.
Caution Do not charge the battery pack if the ambient temperature exceeds 104 degrees
Fahrenheit (40 degrees Celsius).
Caution Do not expose the battery pack to high storage temperatures (above 140 degrees
Fahrenheit, 60 degrees Celsius).
Caution When discarding a battery pack, contact your local waste disposal provider regarding
local restrictions on the disposal or recycling of batteries.
Caution To obtain a replacement battery, contact your local dealer. Use only the batteries that have
a Cisco part number.
Standard battery—CP-BATT-7921G-STD
Extended use battery—CP-BATT-7921G-EXT
Caution Use only the Cisco power supply that was provided with your phone. If you need to replace

Cisco Unified Wireless IP Phone 7921G for Cisco Unified CallManager 4.1, 4.2, 5.0 and Later 5
Power Outage
Your accessibility to emergency service through the phone is dependent on the wireless access point
being powered. If there is an interruption in the power supply, Service and Emergency Calling Service
dialing will not function until power is restored. In the case of a power failure or disruption, you may
need to reset or reconfigure equipment before using the Service or Emergency Calling Service dialing.
Regulatory Domains
The radio frequency (RF) for this phone is configured for a specific regulatory domain. If you use this
phone outside of its regulatory domain, the phone will not function properly, and you might violate
local regulations.
Healthcare Environments
This product is not a medical device and may use an unlicensed frequency band that is susceptible to
interference from other devices or equipment.
Using External Devices
The following information applies when you use external devices with the Cisco Unified Wireless
IP Phone:
Cisco recommends the use of good quality external devices (such as headsets) that are shielded against
unwanted radio frequency (RF) and audio frequency (AF) signals.
Depending on the quality of these devices and their proximity to other devices such as mobile phones
or two-way radios, some audio noise may still occur. In these cases, Cisco recommends that you take
one or more of the following actions:
• Move the external device away from the source of the RF or AF signals.
• Route the external device cables away from the source of the RF or AF signals.
• Use shielded cables for the external device, or use cables with a better shield and connector.
• Shorten the length of the external device cable.
• Apply ferrites or other such devices on the cables for the external device.
Cisco cannot guarantee the performance of the system because Cisco has no control over the quality
of external devices, cables, and connectors. The system will perform adequately when suitable devices
are attached using good quality cables and connectors.
Caution In European Union countries, use only external headsets that are fully compliant with the
EMC Directive [89/336/EC].
Accessibility Features
A list of accessibility features is available upon request.

6OL-10806-02

Accessories for the Cisco Unified Wireless IP Phone 7921G
The following phone accessories are available for your phone:
• Standard and extended batteries
• AC power supplies for different geographical areas
• Desktop charger with speakerphone
• Carrying cases
• Lock sets
For a complete list and description of accessories, refer to this guide: Cisco Unified Wireless IP Phone
7921G Accessory Guide.
Headset Information
To use a headset, see Using a Handset, Headset, and Speakerphone, page 45. Although Cisco Systems
performs some internal testing of third-party headsets for use with the Cisco Unified IP Phones, Cisco
does not certify or support products from headset or handset vendors. Because of the inherent
environmental and hardware inconsistencies in the locations where Cisco Unified IP Phones are
deployed, there is not a single “best” solution that is optimal for all environments. Cisco recommends
that customers test the headsets that work best in their environment before deploying a large number
of units in their network.
