Toshiba MA-290-100 SERIES - Manual (Page 16)

Programmable selections are also provided as to single- or multi­
validation, validation compulsion on certain transaction keys, etc«
If the "SLP" lamp flickers, it means that validation compulsion is
programmed for the last item entered. In this case, insert a slip
into the validation slot and depress the [VALIDATE] key; no other
operations are allowed until the compulsory validation is executed.
If validation compulsion is programmed on any media key to finalize a
sale, the drawer will not open on finalizing the sale, but will open
on printing the validation slip by the [VALIDATE] key depression.
ITEM
CORR
ITEM CORRECT KEY [ITEM CORR]
This key is used to remove the last line item from the bill, printing
a line through that item on the receipt and journal.
To operate, simply depress the [ITEM CORR] key immediately after the
wrong item is entered and printed.
The item- correct function is effective even when a numeric entry and
a [C] key depression are inserted between the line item to be
corrected and the [ITEM CORR] key depression.
The [ITEM CORR] key will function to correct any last item entered
through a Department, PLU, [%+], [^-], [DOLL DISC], [TAX](Manual Tax),
[PB+], [PB-], [VND CPN], [STR CPN], [BTL RTN], [RTN MDSE] keys, or
Received-on-Account, or Paid-Out items.
However, the (ITEM CORR] key will not function to correct any lines
already entered before the last line item (refer to the [VOID] key
description for such a purpose), or even the last line item entered
through media keys, [ST], [#], [VOID], [EX], [SI/TL], or [ITEM CORR]
itself.
VOID
VOID KEY [VOID]
The [VOID] key is used to void an item entered previously (before the
last line item) within a sale, in which case the [ITEM CORR] key will
not function.
To operate, depress the [VOID] key before or during a normal
department or PLU entry sequence.
The [VOID] key may function to void a previous item through a positive
department or a positive PLU, or a combination or "poisitive
department/PLU plus [%+]/[%-]" entry, but not any other kind of items.
Unless the "Credit Balance" option is selected, voiding to result the
sale total negative will go into an error.
This key may be programmed to require the "MGR" position of the Mode
Lock.
