Toshiba TEC MA-230 - Manual (Page 15)

To enter a price extended by multiplication, enter the quantity
first, depress the [@/FOR] key, enter the unit price, and then
depress the appropriate department key. A multiplication entry will
not be repeated by depressing the same department key again.
PRESET DEPARTMENT KEY
A preset key is a key which has already price programmed in it. It
is therefore unnecessary to enter the price of an item; simply
depress the key to register the sale of one item.
To multiply a preset department price by a quantity, enter the
quantity first, depress the [@/FOR] key, and then depress the preset
department key. The [0/FOR] key in this sequence may be omitted
when the quantity is of a one-digit value (1 to 9).
If a price different from the preset one must be entered, depress
the [PR OPEN] key either before or after the required price entry on
the numeric keyboard, prior to the department key depression.
Each department key can be programmed with positive or negative
status, tax status, and HALC (High Amount Listing Capacity).
When a department is programmed as a negative department, a price
entry can not be repeated by depressing the department key again.
Neither can a price entry be repeated when the [RTN MDSE] or [PR OPEN]
key has been depressed prior to any department key depression.
The department keys may be programmed to be used as "Signle-item"
keys. See the description of "Single-item Department Keys" on page

% +
PERCENT CHARGE KEY ... [ % + ]
This key is used to add a percent rate to a sale. If the preset rate
is to be added, depress the [%+] key without a prior numeric entry.
If a rate different from the preset one is required, 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
entry if only that item requires the percent addition, or after the
[ST] key has been depressed if required on the total bill. The
percent rate and the amount are printed and added to the sales total.
The percent rate may be within the range from 0.001 to 99.9999(%).
The fraction resulted from the percentage calculation is usually
programmed to be rounded off. However, it can be programmed to be
rounded up or discarded.
Usually, the [%+] key operations may be performed as many times as
required after obtaining the sub-total. However, it can be programmed
to prohibit more than once, by the system option.
The [%+] key may be operated on a PB+ (positive previous balance)
entry, in addition to a department or PLU item entry.
The [%+] key is programmed with either taxable or non-taxable status.
The [TX/M] key may be used to reverse this programmed tax status.
