 
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. 
Connections may be subject to 
interference from obstructions, such 
as walls, or other electronic devices.
The headset is compliant with the 
Bluetooth Specification 2.1 + EDR 
supporting the Headset Profile 1.1 and 
Hands-Free Profile 1.5. Check with the 
manufacturers of other devices to 
determine their compatibility with 
this device.
