Hi.
As long as the machine has the standard PLUs on the keyboard:

Turn key to PGM2 mode.
Type 1210
Then press . (decimal point)
Then press X (multiplication. Sometimes labelled @/FOR)
Then type the PLU number to be changed (using the numeric keypad).
Then press X
Then type new price (no decimal point)
Then press ST (SUBTOTAL)
Then press TL (CASH)

If you don't know the PLU numbers, you will need to read the PLU programming to get them. Just let me know if you have any trouble.
