Item Registrations
All registrations on ER-390M 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 can be into PLUs by entering the PLU code
number and pressing the PLU key on the keyboard or by using a barcode
scanner.
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
