Re: tax rate, user guide

Your decimal has to be on the +. then you go to set rate type in the % and turn off. that way it wont be off any cents.

Set Tax Rate

First clear all w/ ON/AC.
Enter the tax rate desired eg. 7 for 7% (can you tell I'm in PA)
Press RATE then TAX+
Press C/CE.
The next time you use TAX+ it will calculate and add the value that you set.
Do the same for TAX-, you can use a different value for each as they are separate memories.
