The following information applies when you use external devices with the
Cisco IP Phone:
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 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 IP Conference Station to the network and to a power source
before using it.
