Need to clear old tax rate and set new tax rate.

  1. To change the tax rate, first press AC.
  2. Then press SET % for 2 seconds.
  3. Next, press TAX+, then enter the new or current tax rate.
  4. Enter the rate for a single digit tax rate such as 5% as 5, a single number; if you have a fractional percentage rate, such as 5.75%, enter it just that way: the 5, then a decimal and followed by 7& 5.
  5. Then press SET % and you're done!

It shouldn't be difficult, as this is a simple model. I need to know what sort of business it is used in, then I can help you to set it up the usual way. How many taxes do you have, and what percentages?
