Installing the Cisco Unified IP Video Phone

Note
OL-8726-02
Cisco recommends the use of good quality external devices that are screened
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 screened cables for the external device, or use cables with a better screen
•
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 by using good quality
cables and connectors.
In European Union countries, use only external speakers, microphones, and
headsets that are fully compliant with the EMC Directive [89/336/EC].
You must connect the Cisco Unified IP Video Phone to the network and to a power
source before using it. See
Before using an external headset, read the
Cisco Unified IP Video Phone" section on page 3-6
information.
