Problem with the Logitech MX3200 KB & Mouse combo

[Sgt_Strider]

It would be great if owners of this keyboard/mouse combo is able to help me. I can't seem to get the keyboard to work at all. The keyboard does turn on, but I can't get it to sync with the receiver. Only the mouse works. I did press the connect button in the back of the keyboard, but it doesn't seem to do anything. Any advice on what to do?
