Bluetooth Wireless Headset Performance
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 these 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 external devices, cables, and connectors.
Caution
In European Union countries, use only external speakers, microphones, and headsets that are fully compliant
with the EMC Directive [89/336/EC].
Bluetooth Wireless Headset Performance
The Cisco Unified IP Phone 8945 supports 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 of 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.
FCC Compliance Statements
The Federal Communications Commission requires compliance statements for the following:
FCC Part 15.21 Statement
