•
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 external devices, 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].
Caution
Bluetooth Wireless Headset Performance
The Cisco IP Phones support Bluetooth Class 2 technology when the headsets support Bluetooth. Bluetooth
enables low-bandwidth wireless connections within a range of 30 feet (10 meters). The best performance is
in the 3- to 6-foot (1- to 2-meter) range. You can connect up to five headsets, but only the last one connected
is used as the default.
Because there can be potential interference issues, Cisco recommends that you move 802.11b/g devices,
Bluetooth devices, microwave ovens, and large metal objects away from the wireless headset.
For a Bluetooth wireless headset to work, it does not need to be within direct line-of-sight of the phone, but
some barriers, such as walls or doors, and interference from other electronic devices, can affect the connection.
Power Information
Connect your Cisco IP phone to your LAN using a CAT 5e Ethernet cable to enable full functionality of your
Cisco IP phone. If your Ethernet port is equipped with Power over Ethernet (PoE), your Cisco IP phone can
be powered through the LAN port. Do not extend the LAN Ethernet cable outside the building.
FCC Compliance Statements
The Federal Communications Commission requires compliance statements for the following:
FCC Part 15.21 Statement
Changes or modifications not expressly approved by the party responsible for compliance could void the
user’s authority to operate the equipment.
FCC RF Radiation Exposure Statement

users must follow the specific operating instructions for satisfying RF exposure compliance. This transmitter
