Item Registrations
All registrations on ER-420 Series are made into open or preset PLUs.
• In place of traditional PLU keys, some PLUs are located directly on the
keyboard.
• When more items or categories are needed than the number of PLUs available
on the keyboard, registrations through PLUs can be made by entering the PLU
code number and pressing the PLU key on the keyboard.
• This system simplifies reporting by listing all items (regardless of how they are
entered) on the PLU report, while reporting for groups of items or categories is
available from the Group report.
