We tried it and it didn't work. He swore that was the button combination the other customer told him, and it cleared up the block on the pinpad instantly. I was so happy after he told me about it, but so bummed when it didn't work. We tried making it work with numerous permutations, but eventually had to fall back to resetting the pinpad.

Any one know more about this? PM if necessary.
