Safety and Performance Information

Read the following safety notices before installing or using your wireless IP phone.


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


To see translations of the warnings that appear in this publication, refer to the statement number in the Regulatory Compliance and Safety Information for the Cisco Unified Wireless IP Phone 7920 Series and Peripheral Devices document that accompanied this product. You can also find the document at the following URL:



Read the installation instructions before connecting the system to the power source. Statement 1004


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. Statement 361


The plug-socket combination on the battery charger must be accessible at all times because it serves as the main disconnecting device. Statement 1019


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


Do not use the Cisco Unified Wireless IP Phone 7925G and 7926G 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.


Do not charge the battery of Cisco Unified Wireless IP Phone 7925G, 7925G-EX, and 7926G in a potentially explosive environment.


Use CSA or ATEX qualified accessories with the Cisco Unified Wireless IP Phone 7925G-EX in a potentially explosive environment.


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 near such objects.

Battery Safety Notices

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


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


Ultimate disposal of this product should be handled according to all national laws and regulations. Statement 1040


Do not dispose of the battery pack in fire or water. The battery may explode if placed in a fire.


The battery pack is intended for use only with this device.


Do not disassemble, crush, puncture, or incinerate the battery pack.


To avoid risk of fire, burns, or damage to your battery pack, do not allow a metal object to touch the battery contacts.


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.


Do not charge the battery pack if the ambient temperature exceeds 104 degrees Fahrenheit (40 degrees Celsius).


Do not expose the battery pack to high storage temperatures (above 140 degrees Fahrenheit, 60 degrees Celsius).


When discarding a battery pack, contact your local waste disposal provider regarding local restrictions on the disposal or recycling of batteries.


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

Standard battery


Extended use battery


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 list of Cisco part numbers.



Central Europe






North America


United Kingdom



The battery and power supply are not provided with your phone. To order the battery and power supply, contact your local dealer.

Power Outage

The ability to access emergency service through the phone depends 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 the specific regulatory domain, the phone will not function properly, and you might violate local regulations.

Health-Care Environments

This product is not a medical device and uses an unlicensed frequency band that is susceptible to interference from other devices or equipment.

External Devices Usage

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.


In European Union countries, use only external headsets that are fully compliant with the EMC Directive [89/336/EC].

Phone Behavior During Times of Network Congestion

Anything that degrades network performance can affect Cisco IP Phone voice and video quality, and in some cases, can cause a call to drop. Sources of network degradation can include, but are not limited to, the following activities:

  • Administrative tasks, such as an internal port scan or security scan

  • Attacks that occur on your network, such as a Denial of Service attack

To reduce or eliminate any adverse effects to the phones, schedule administrative network tasks during a time when the phones are not being used or exclude the phones from testing.
