That's just the thing, FN+F11 and FN+F12 have no effect. Tried on various computers, same thing. When I do plug in the USB the keyboard lights up, but nothing else works. Must be a faulty keyboard. Just wish there were some sort of reset button underneath the keyboard, or something like that!
My son bought a Masterkeys Lite a few weeks ago. for no apparent reason the keyboard has gone onto Full Keyboard Lock, indicated by a red letter G on the top righthand side of the keyboard. Pressing FN + F11 does nothing to unlock it. All the keys are unresponsive. Is it a faulty keyboard? Is there a way to overide or factory reset the keyboard??
