Question about Casio MS-80TV Scientific Calculator
How do I reset the tax rate?
Hold "set" key until "set exch" appears. Then hit "tax+" key and enter
in correct amount. After amount set then hit "set" key once again to complete set up.
Try that, seems to work on a few Casio models

Hold down the Rate set key until the tax amount already keyed in appears. Type in new amount. Press Rate set key again. Worked on my Casio MJ-100.
