Toshiba TEC MA-230 - Manual (Page 16)

% -
ST
PERCENT DISCOUNT KEY [ % - ]
This key operates in the same fashion as the [ % + ] except that
operation will subtract from instead of adding to a sale.
SUBTOTAL KEY [ST]
This key is used to obtain the subtotal amount without tax 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 concecutively, the first
depression only will print and display the sub-total; further
depressions will only display but not print the subtotal amount.
The system option provides the selection not to print but only display
the subtotal amount even on the first depression of the [ST] key.
TXBL
TL
TAXABLE TOTAL KEY ... [TXBL TL]
This key is used to obtain the contents of the main itemizer (i.e.
subtotal) plus any taxes due. The amount will display only but not
print.
When this key is depressed during a sale with a previous balance
entry, it will display the sale total without the previous balance.
In order to allow add-on operation to follow the use of this key, the
taxes are not added into any totals until an actual finalization is
initiated.
Mandatory depression of this key prior to finalizing is a programmable
option.
R/A
RECEIVED ON ACCOUNT KEY [R/A]
A received-on-account transaction is used to identify money which is
in the drawer but not business. The amount entered is thus included
in the "Cash(or other media)-in-drawer" total but not in the sales
totals.
To operate, enter an amount of payment and then depress the [R/A] key.
Repeat this operation if multiple payments are entered at a time.
The payments thus entered may be finalized by the [AT/TL] (for cash
payments). Other media keys may also function to finalize payments
received on account if not prohibited in the system option. The above
operation can only be performed when the register is outside a sale.
