Refer to these sections for information about the impact of power outages and other devices on your

Cisco Unified IP Phone.

Power Outage

Your accessibility to emergency service through the phone is dependent on the phone 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.

Using External Devices

The following information applies when you use external devices with the Cisco Unified 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.
