full, current records are saved and old data is discarded.
Error Condition
An error condition signals that mis-operation has occurred. It is identified by an audible
tone and an error descriptor appearing on the display.
Error Correct
An error correct operation voids the last item entered, it must be used within a sale.

Flash ROM

Flash ROM is used by the manufacturer to contain the program that runs the register.
Flash ROMs maintain memory when power is off, allowing the register to be especially
stable and reliable. When the register's program is improved, or updated, the Flash ROM
can be updated by a qualified service technician through a utility in the register.
Gallonage
To simplify gasoline transactions, PLUs can be designated to calculate gallons sold on fuel
purchases. The price of the fuel sold is entered as it would be in a normal "open" PLU.
However the price per gallon of fuel is entered where the PLU preset price is normally
maintained. When fuel is sold, the register will refer to the programmed price per gallon
and calculate the number of gallons sold. Both the gallons pumped and dollar amount of
the gas purchase are conveniently printed on the customer receipt and sales journal. This
provides all the necessary information for a customer that needs a receipt for gas purchases.
The total of gallons sold is also maintained on the appropriate PLU report, in the place of
the PLU item counter. Several gallonage PLUs could be placed on the keyboard to
maintain records for different pumps, or types of fuel. Thus, the dollar and gallon totals
can provide a useful security check against separate pump totals.
Groups (PLU Groups)
Groups are used to organize sets of items. For example, in a restaurant Grill Items,
Drinks, and Ice Cream items might be separated into different groups. Up to 99 group
totals are available. Group reporting is available on the group report.
HALO
The high amount lock-out (HALO) limits the amount allowed to be entered in a PLU, or
function key.
HASH
Merchants often sell non-merchandise items, such as lottery tickets, or bottle deposits, that
they do not wish to account for as reportable revenue. HASH PLUs are useful to account
for non-revenue income. They will add to the appropriate totals on the PLU report, they
will add to the transaction totals, and they will be accountable for in drawer totals, but they
will not affect the merchants, NET SALES, GROSS SALES or NON-RESETTABLE
GRAND TOTAL. As a system of options programming, HASH can be defined to not add
to the transaction (NON-ADD).
Link (PLU Link)
Use linked PLUs if you wish the registration a PLU to automatically cause the registration
of another PLU (for example to automatically add a bottle deposit.) Linked PLUs are set
