 
■ Bluetooth wireless technology
Bluetooth wireless technology allows 
you to connect compatible devices 
without cables. The headset and the 
other device do not need to be in line 
of sight, but they should be within 10 
metres (33 feet) of each other. The 
closer the headset and the other 
device are to each other, the better 
the performance. The optimal 
operating range is shown in dark grey 
in the picture. The connection is 
subject to interference from distance and obstructions (shown in light 
grey) or other electronic devices.
The headset is compliant with the Bluetooth Specification 2.1 + EDR 
supporting the following profiles: Headset Profile 1.1, Hands-Free 
<10m

of other devices to determine their compatibility with this device.
