The keyboard came badly taped together (previously opened) with no USB receiver so I can’t even use it.
It also says on the package that it comes with AA batteries and did not. That is much less important than the receiver though.
Sorry for the problem. Did you look on the bottom of the keyboard for the receiver? Some mice/keyboards have a place to store it built in.
If that’s no good, you can contact Rock Candy directly. They should be able to get you the receiver.
If all else fails, please use the Customer Service form for assistance.
