I found a Bluetooth on the street about half an hour ago, about to be stepped on or run over. I picked it up and took it home, hoping I'd find a way of returning it to its owner. I figure the internet can help me with that. It's a Plantronics Explorer 240. I have the FCC and IC on it, too. It's flashing blue lights and is probably synced to a phone, but I have no idea how to operate it and I don't have a charger. Tips?
