%1 and %2 Key Programming 

There are two percentage keys on the keyboard: %1 and %2.  The %1 key applies a surcharge.  
The %2 key applies a discount.  Without any further programming, you can apply a discount or 
surcharge to an individual item or to the subtotal of a sale by entering a percentage and pressing 
the %1 or %2 key.  This program allows you to: 

z

  decide to calculate any taxes before or after the percentage is applied 

z

  set a preset percentage for the %1 or %2 key 

z

  if a preset percentage is set, decide if you wish to also allow a percentage to be entered 

z

  inactivate the key
