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.
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].
