- (Minus) Key Programming
The - (Minus) key is used to enter the amount of a coupon that is subtracted from the sale.
• The - (Minus) key can programmed to be taxable or non-taxable. In other words, when
you are subtracting a coupon, you can calculate sales tax on the net or the gross cost of
the item. If the - (Minus) key is taxable, you will calculate sales tax on the net cost of
the item. If the - (Minus) key is -non-taxable, you will calculate sales tax on the gross
cost of the item.
• You can also program limit errors by setting the maximum amount that may be entered
into the - (Minus) key. For example, setting a 3 digit limit means the maximum you
can enter is $9.99. This is referred to as the High Digit Lock Out, or HDLO.
