Set Tax:

 

If everything installed properly, set the tax rate as follows:

 

 

 

1)  On start-up or after a Clear [C], enter the new tax rate (e.g. 17).

  1. 2) The upper right [set tax] button should show.

  2. 3) Press this button to set the tax rate.

 

If the two setting buttons on the upper right do not appear, you may have to re-install the program.
