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.
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

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
To obtain a battery, contact your local dealer. Use only the batteries
that have a Cisco part number.
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.
The battery and power supply are not provided with your phone. To
order the battery and power supply, contact your local dealer.
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.
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.
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
tasks, such as an internal port scan or security scan
occur on your network, such as a Denial of Service
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
