I would like to just put in a 20% discount for items in the Sharp A470. I have looked at the manual, but am not understanding it. I know there is a key on there right now that does a 50% discount if I could just adjust that it would be okay.

Hi. Look in the manual at the section for adjusting the rate of the %1 key. I can't remember off the top of my head. It usually has other options like changing the sign/ status. just leave them as they are. You might have to use the decimal e.g 25.00 when setting it.
