I have two SAM4s, ER-5200 cash registers. I have been having problems with them both, so decided to do a full master reset. Key to 's' position, turn off, holding 'check' turn back on, then the four corners in order. I am now getting error code E47. I thought it may have just been one, but the other has done exactly the same. I cannot find a solution to this listed anywhere. Please help, Christmas is fast approaching, and I need them both....
I don't have an answer, just the same question. Patrick's answer doesn't work for me. Have tried with key in every position.
Any help...
Thanks
Graham
