Need to change tax function on Sharp EL-334A

I had the same problem and finally figured it out. Here's what you do:

Press C-CE twice
Press +TAX (Rate set)
Key in your new tax rate as an integer (e.g. 5)
Press +Tax (Rate set) again
Press C-CE

Then you're ready to calculate with the new rate!

Now what's the GT button for?
