USING THE VOYAGER LEGEND UC 

Once you plug the Bluetooth adapter into your PC the OS will automatically detect it and use it as the default communications device (at least that's what happened in Windows 7/8).

Skype also detects it automatically and sets it as the default device for incoming/outgoing calls.

Unfortunately the headset updater is not compatible at this time with the Legend UC version, however because of that we started playing around with the Find MyHeadset android app which can actually save you from quite a bit of trouble if you ever misplace the headset.
