SOURCE: I have a casio te4500f, problem changing prices

I know its been about 2 weeks in coming, but this is really easy to do. Generally casio does all its pricing from P1(program1 to get there turn the key to PGM). The machine will recognize the position of the key and automatically go to P1. Once there you can enter a price without decimals and press the button that you want that price on. That is providing the PLU's are set up. The PLU's are the items that you sell like hamburger, milk, coke etc. When done press subtotal and turn your key back to REG and keep on pluggin!!!!!
