WLU Applications
A WLU can list PLUs with condiment status, ordinary PLUs, and/or functions.
 A WLU listing condiments may be linked to an item so that immediately
after the item is registered, condiment options for that item are displayed.
 A WLU listing PLUs can be displayed by pressing a WLU function key
on the keyboard. In this way, a list of similar items, such as a wine list,
can be displayed for easy selection and entry.
 A WLU listing functions can be displayed by pressing a WLU key on the
keyboard. In this way, functions that are only used occasionally can be
accessed indirectly, or if there are insufficient key locations on the
keyboard for all the functions you wish to use, some of them could be
located on a WLU. (A function need not be on the keyboard in order to be
placed on a WLU.)
 Any WLU can be set to list combinations of Condiment PLUs, ordinary
PLUs or functions.
Programs Notes for Setting up WLUs
 Check your memory allocation settings (see “S-Mode Programming-
Memory Allocation” in the Program Manual.) The total number of
WLUs available is determined in memory allocation. The default is 10
WLUs; the maximum is 999 WLUs, if memory is available. The number
of items that can be listed in a WLU is also set in memory allocation. The
default is 28 items: the maximum is 50 items.
 Program the items for each WLU. First, set the options for each
individual WLU, then add or delete items as necessary. (See “P-Mode
Programming-Window Look Up (WLU)” in the Program Manual.)
 If a WLU is to be activated by the registration of an item, go to PLU
programming and enter the WLU number in the ACTIVATE WLU# field.
(See “P-Mode Programming-PLU Programming” in the Program
Manual.)
 If a WLU is to be activated by pressing a function key, identify the key as
a WLU key and set the WLU# that is to be activated. (See “P-Mode
Programming-Keyboard Key Relocation ” in the Program Manual.)
