I bought this keyboard (and mouse) and wonder, do I need to buy a special USP stick? (The USB sticks used to come with the wireless peripherals; do today's computers have RF built in?)
Bluetooth is now built into all laptops and many desktops, but that set isn't a bluetooth set. It should come with a wireless USB dongle in the box. If you can't see it separately look on the underside of the mouse or under it's cover (the same that holds the batteries)
Oh my g-d, it was in the battery plastic. I had worked so hard with it to get the batteries out, and I still missed it (I checked the other packaging material very carefully). Thank you!!! (I feel somewhat sheepish :-(
