The - (Minus) key is used to enter the amount of a coupon that is subtracted from the sale.   

z

  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.   

z

  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.   

1.  Turn the control lock to the PGM position.
