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.

Getting Started

Warning

Voice over IP (VoIP) service and the emergency calling service do not function if power fails or is disrupted. After power is restored, you might have to reset or reconfigure equipment to regain access to VoIP and the emergency calling service. In the USA, this emergency number is 911. You need to be aware of the emergency number in your country.

The plug-socket combination on the battery charger must be accessible at all times because it serves as the main disconnecting device.

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.

Do not use the wireless IP phone 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.

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.

Statement 361

Statement 1019

Statement 1045

Battery Safety Notices

These battery safety notices apply to the batteries that are approved by the Cisco Unified Wireless IP Phone 7921G manufacturer.

Warning

Cisco Unified Wireless IP Phone 7921G Phone Guide for Cisco Unified Communications Manager 7.0 3

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.

Ultimate disposal of this product should be handled according to all national laws and regulations.

Statement 1040

Statement 1015

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.

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 battery, contact your local dealer. Use only the batteries that have a Cisco part

number.

Getting Started

Caution Use only the Cisco power supply that is compatible with your phone. To order your power

supply, contact your local dealer and refer to the following list of Cisco part numbers: 

Australia—CP-PWR-7921G-AU= Central Europe—CP-PWR-7921G-CE= China—CP-PWR-7921G-CN= Japan—CP-PWR-7921G-JP= North America—CP-PWR-7921G-NA= United Kingdom—CP-PWR-7921G-UK=

Note The battery and power supply are not provided with your phone. To order the battery and

power supply, contact your local dealer.

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

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.

Cisco Unified Wireless IP Phone 7921G Phone Guide for Cisco Unified Communications Manager 7.0 5

• 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].

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

• Multi-charger

• Carrying cases

• Lock sets

For a complete list and description of accessories, see the Cisco Unified Wireless IP Phone 7921G

Accessory Guide.

Headset Information

To use a headset, see Using a Handset, Headset, and Speakerphone, page 65. 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

14 OL-16131-01

IP Phones are

Connecting Your Phone

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.

In some instances, the mechanics or electronics of various headsets can cause remote parties to hear an echo of their own voice when they speak to Cisco Unified IP Phone users.

Cisco Systems recommends the use of good quality external devices, like headsets that are screened 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 cell phones and two-way radios, some audio noise may still occur. See

The primary reason that a particular headset would be inappropriate for the Cisco Unified IP Phone is the potential for an audible hum. This hum can be heard by either the remote party or by both the remote party and you, the Cisco Unified IP Phone user. Some potential humming or buzzing sounds can be caused by a range of outside sources, for example, electric lights, being near electric motors, large PC monitors.

Using External Devices, page 5 for more information.

Audio Quality Subjective to the User

Beyond the physical, mechanical and technical performance, the audio portion of a headset must sound good to you (the user) and to the party on the far end. Sound is subjective and Cisco cannot guarantee the performance of any headsets, but some of the headsets on the sites listed below have been reported to perform well on Cisco Unified IP Phones.

Nevertheless, it is ultimately the customer's responsibility to test this equipment in their own environment to determine suitable performance.

For information about headsets for your phone, see the Cisco Unified Wireless IP Phone 7921G

Accessory Guide and these web sites:
