|The keyboard itself uses "Canada 210" as the protocol for the wireless, so the easiest thing to check is to see if the receiver you have for it says "Canada 210" on the bottom, usually in fine print. If the receiver says "Canada 310" it might work, but I've never tested a keyboard between 210 and 310 receivers, only mice and they work.|
If the receiver and keyboard match make sure the keyboard batteries are good and installed in the correct position. If they are look on the bottom of the keyboard for a small button, from what I see on google images it's to the left of the product label. Press it then press the button on the receiver. If the receiver has a light it should blink until the keyboard is properly synced.
Will return once all the ass holes are gone, in about 2 years or so.
