Question about Casio HR-100TM Two-Color Portable Printing Calculator, 12-Digit Lcd
How can I reset my machine to the it was when I bought it my grandson got it and pushed all the buttons on it and now I cannot get it to add and subtract. When I try to use it all I get are shapes and signs that does not have anything to do with what I am trying to do. I have tried to reset the reset button but it does no good. I have tried doing it unplugged and plugged in. I just use it for bills. PLEASE HELP ME! THANKS
Could it have gotten dropped, or wet? If it got wet, leaving it to dry for a few days might help. It sounds like a lot more happened to it than just pushed buttons. I think I'd just get a new one and keep it out of reach.
