Product Safety and Security
Caution
To obtain a battery, contact your local dealer. Use only the batteries that have a Cisco part number.
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
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.
• Do not dispose of the battery pack in fire or water. The battery may explode if placed in a fire.
• Do not disassemble, crush, puncture, or incinerate the battery pack.
• 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.
