Safety and Performance Information
Power outages and other devices can affect your Cisco Unified IP Phone.
Power Outage
Your access to emergency service through the phone depends on the phone being powered. If there is a power
interruption, Service and Emergency Calling Service dialing will not function until power is restored. In case
of a power failure or disruption, you may need to reset or reconfigure the equipment before using the Service
or Emergency Calling Service dialing.
External Devices
Cisco recommends using good quality external devices such as headsets, cables, and connectors that are
shielded against unwanted radio frequency (RF) and audio frequency (AF) signals.
Not all Cisco IP Telephony products support external devices, cords or cables. For more information,
consult the documentation for your phone.
Note
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 these actions:
