Power Outage

Your accessibility to emergency service through the phone is dependent 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 its regulatory domain, the phone will not function properly, and you might violate

local regulations.

Healthcare Environments

This product is not a medical device and may use an unlicensed frequency band that is susceptible to

interference from other devices or equipment.

Using External Devices

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.

Caution

In European Union countries, use only external headsets that are fully compliant with the

EMC Directive [89/336/EC].
