From the "Quick Start" portion of the Royal Alpha 9150 instruction manual, page 12:
Turn the key to the "PRG" program position.
To set a single fixed TAX RATE: If a mistake is made at any time while programming the sales tax, or you receive an error tone, press CLEAR and start over with Step A.
A. Using the gray numeric keys ENTER (1). PRESS [TAX 1].
B. ENTER the TAX RATE as a 4 digit number, then PRESS [AMT TEND/TOTAL].
Example: If your state tax rate is 6%: Using the gray numeric keys ENTER (6000), then PRESS [AMT TEND/TOTAL].
Note: A tax rate of 6.5% will program as (6500). A tax rate of 8.75% will program as (8750).
