Bluetooth Wireless Headset Performance (8800 Series); Ways To Provide Power To Your Phone - Cisco IP Phone 7800 Series User Manual

Bluetooth Wireless Headset Performance (8800 Series)

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, we recommend 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 (8800 Series)
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 of potential interference issues, we recommend that you move 802.11b/g devices, Bluetooth devices,
microwave ovens, and large metal objects away from the wireless headset.
The Bluetooth wireless headset does not need to be within direct line-of-sight of the phone. However, some
barriers, such as walls or doors, and interference from other electronic devices, can affect the connection.
Note The Cisco IP Phone 7811, 7821, 7841, and 7861 does not support Bluetooth.
The Cisco IP Conference Phone 7832 does not support Bluetooth headsets.
