Modifier Key
Pressing a modifier key alters the next PLU registered, either by changing the code number
of the PLU so that a different item is registered, or by just adding the modifier descriptor and
registering the same PLU. See "Modifier 1-5" in the "Program Mode Programming"
chapter in order to determine how the modifier key will affect the PLU entry.
Modifiers can be:
• Stay down so that registrations will be modified by the same modifier until
another modifier is selected,
• Pop-up after each item to register, for example large, medium or small soft
drink,
• Pop-up after each transaction to register, for example, toppings of various
pizza sizes.
See "System Options" in the "Program Mode Programming" chapter to select stay down/pop-
up status.
