I have bougth Plantronics Explorer 340 but cannot use it as I thougth I would: cannot connect via bluetooth from PC. I wanted to use it as mobile Haedset while skyping on PC. Is that not possible with Plantronics Explorer 340 ?
Sorry for the stupid question, but just wanted to make sure: Does your PC already have bluetooth connectivity?
According to this website, you must have the "LM Technologies Bluetooth dongle/adapter" which allows you to connect to your PC and use it with programs like Skype or MSN Live Messenger. I'm guessing you can just buy any bluetooth adapter for your PC, plug it into your PC's USB port and then connect your bluetooth device.
A quick search on the LM adapter and I find this. If you DO have a bluetooth connection on your PC and still having issues then I'm sorry, I have no solution.
