TAX EXEMPT
Press the TAX EXEMPT key to exempt tax 1, tax 2, tax 3, and/or tax 4
from the entire sale.
TAX (1-4) SHIFT
When pressed before a PLU entry, the tax shift keys reverse the tax status
of the PLU, i.e., a PLU with non-tax status would become taxable or a
PLU with tax status would become non-taxable.
TIP
The TIP key allows a gratuity to be added to a guest check before
payment. The tip amount is deducted from the Cash-in-Drawer amount
for the Clerk/Cashier closing the guest check.
The TIP key may be programmed as either a percentage or amount. If
programmed as a percentage, tax programming defines whether the
percentage is calculated on the net amount or the amount after taxes.
VOID
Use to correct an item entered earlier within a sale. The VOID key
corrects the appropriate totals and counters. To correct the last item, use
the ERROR CORR key. For void operations outside of a sale
(Transaction Void), use the VOID position on the control lock. The
Financial report records totals for each type of void separately.
VALID
Press the VALID key to print a one-line validation on
a separate form or piece of paper. A any item registration, discount or
payment may be validated.
WASTE
The WASTE key allows control of inventory by accounting for items,
which must be removed from stock due to spoilage, breakage or mistakes.
Press the WASTE key before entering wasted items, then press the
WASTE key again to finalise. The WASTE key may be under manager
control, requiring the control lock to be in the X position. The WASTE
operation is not allowed within a sale.
