Toshiba MA-290-100 SERIES - Manual (Page 13)

The bottle return amount is limited by the HALC of the department
through which the amount is entered.
Quantity extension (multiplication) is possible by depressing the
[BTL RTN] key during a normal department multiplication sequence.
None of the [RTN MDSE], [VOID], and [STR CPN] keys will function
with the [BTL RTN] key in one-item operation sequence.
The tax and SI statuses of the bottle return amount will be ruled by
the department through which the amount is entered.
The [BTL RTN] key may be programmed to require the "MGR" position of
the Mode Lock.
RTN
MDSE
RETURNED MERCHANDISE KEY [RTN MDSE]
This key is used to refund money to a customer who has returned goods
to the store.
To operate, depress the [RTN MDSE] key during a normal Department or
PLU entry sequence (quantity extension is also possible). The amount
is automatically printed and deducted from the bill.
This key may be programmed to require the "MGR" post ion of the Mode
Lock.
%+
PERCENT CHARGE KEY [%+]
This key is used to add a percentage rate to a sale. If the preset
percent rate is to be added, depress the [ % + ] key without a prior
numeric entry. If a rate different from the preset one is to be
added, enter the desired rate on the numeric keyboard and then depress
the [%+] key. The manual rate will take priority.
To operate, depress the [%+] key either immediately after a
department, PLU, or positive Previous Balance item if only that item
requires the percentage addition, or after the [ST] key if required on
the total bill. The percent rate and the amount are printed and will
be added to the sale total.
The percent rate may be within the range from 0.001 to 99.999%. The
fraction resulted from the percentage calculation is usually
programmed to be rounded of f. However, it can be programmed to be
rounded up or discarded.
Usually, a % key operation after a subtotal is once obtained is
allowed any number of times. However, it may be programmed to
prohibit it more than once.
%-
PERCENT DISCOUNT KEY [ % - ]
This key operates in the same fashion as the [%+] key except that
operation will subtract from instead of adding to a sale. A preset
rate independent from that of the [%+] key may be programmed.
