If you're talking about the preset prices on the keyboard keys, here's the procedure:

1) Turn the key to P
2) Enter 200, press SBTL
3) Press the key on the keyboard that you want to set the price for.
4) Enter the new price. You must enter all digits, no decimal point. EX. for $1, enter 100. for $1.25, enter 125. for $.25, enter 25, etc.
5) Press X/TIME
6) You can repeat steps 3 - 5 to program additional keys. Press CASH when you are finished.

Good luck ...
