Toshiba MA-290-100 SERIES - Manual (Page 19)

If a price different from the preset one must be entered through
numeric keys into a preset department, depress the [PR OPEN] key
either before or after the price entry.
Each department is also programmed with either positive or negative
use, a HALC (High Amount Listing Capacity), LALC (Low Amount Listing
Capacity), tax and SI (Selective Itemization) status.
A department item with [RTN MDSE], [PR OPEN], or [SHIFT] key, or a
negative department item can not be repeated.
A department key can also be programmed to be used as a "Single-item
Department" key. If so programmed, the department entry routine above
mentioned will immediately finalize the sale as cash without
depressing any of the media keys, when operated outside a sale. The
Single-item Department key will function, however, just as an ordinary
itemized department key if used inside a sale.
As for additional Department Keys or Shifted Departments, refer to the
"OTHER OPTIONAL KEYS" section.
ST
SUBTOTAL KEY [ST]
This key is used to obtain the subtotal amount (sale total without
taxes) during a sale. When this key is depressed after all the items
have been rung up, the subtotal of the sale is printed and displayed.
If the [ST] key is depressed more than once consecutively, the first
depression only will print and display the subtotal; further
depressions will only display but not print the subtotal amount.
A programmable option provides the selection not to print but only
display the subtotal even on the first depression of the [ST] key.
In charge posting, a depression of the
amount without previous balance.

TXBL
TL
TAXABLE TOTAL KEY [TXBL TL]
This key is used to display the contents of the sale total plus any
taxes due. The amount will display only but not print.
In order to allow add-on operation following the use of this key, the
taxes are not added into any totals until actual finalization is
initiated.
Mandatory depression of this key prior to finalizing a sale is a
programmable option.
If the "TOTAL VALIDATION" option is selected, depressing the
[VALIDATE] key after a [TXBL TL] key depression prints the sale total
on the validation slip, and therefore, only a finalizing operation
then is allowed.
In charge posting, depressing the [TXBL TL] key displays the amount
including taxes but excluding the previous balance.
