Percent Key Operations
A total of five % functions are available. %1 and %2 are located on the default keyboard. Your
keyboard may be different. More or less % keys may be located on the keyboard, or they may be
located on one of the function look up menu keys.
Each function is individually programmable to add or subtract, from an individual item or from a sale
total, amounts (coupons) or percentages. You can also program the percentage key taxable or non-
taxable, so that sales taxes are calculated on the net, or the gross amount of the item or sale. You can
also program preset prices or percentages.
The operation examples in this section show the percentage key in a variety of configurations. See
"Function Key Programming" in the "Program Mode Programming" chapter to assign a specific
function to each percentage key.
