Hi. We don't have this model, but if the book says you can use three rates, then that is usually your lot. You may be able to use a %+ key to manually add tax. Your machine will need to have the %+ function though. If it has a percent key on the keyboard, it is usually a discount key which will remove a percentage. Some machines can be changed to add a percentage instead. Check your programming manual to see if it has this function.
