Question about Monroe 2020Plus Calculator
I have Sharp er-a330 cash register
when I pressed number and item, always comes E on display.. can't do nothing..
how I can solve this prob'
The Sharp ER-A330 and ER-A310 both have a calculator function that turned out to be just trouble for users who don't need it and don't know how to turn it off. At the bottom-left of the keyboard is a button labeled PO. Normally you enter a dollar amount and touch that to Pay Out money from the till. On these models it also activates the calculator mode, allowing you to add and subtract numbers without affecting sales.Touch PO to turn calculator mode back off, and you'll have a cash register again.
Let me know if this isn't the fix you need.
