Explanation of keys
[0~9].....................
[00, 000]
Keys in numbers from 0 to 9, 00, and 000. If the number of display digits exceeds
10, 12 or 14, key entry is invalid.
[] ......................... If this key is pressed after a key operation except data entry, the display is cleared
and entry of [] is stored in memory. The decimal point is shifted for subsequent
data entry. If the [] key is pressed during data entry, display does not change.
[
+, ] ..................... Add or subtract operation data and display the result. The decimal point is floating
except when A mode is specified. Addition or subtraction can be performed
repeatedly.
If these key are pressed in multiplication/division mode or in constant calculation
mode, add or subtract display data to addition/subtraction registers, then display
the result. At this time, in the operation mode multiplicand or divisor do not
change.
These keys increment or decrement the item counter. In the following operation
mode, the operations are executed, and the results are printed and displayed. At
that time, addition or subtraction using the addition/subtraction register is not
executed.
1)
Percent discount/add-on calculation
a
× b% + .... a + (ab/100)
c%
+ ..... a + (ac/100)
a
× b% .... a (ab/100)
c%
..... a (ac/100)
Percent discount/add-on with constants are calculated as above.
[] ......................... Prints and displays the intermediate result in addition/subtraction register. In
item count mode, prints the contents of the item counter before the calculation
result printing.
Contents of data register or stored arithmetic instruction are not changed.
[*] ......................... Prints and displays the result in addition/subtraction register. Automatically feeds
paper one line. In item count mode, the contents of the item counter are printed
before the calculation result printing.
After this key operation, the contents of the addition/subtraction register are
cleared. The contents of the item counter are cleared at the first
addition/subtraction in next step. The contents of the data register or stored
arithmetic instruction are not changed. When GT mode is specified, the result of
addition/subtraction is added to the GT memory.
[M
+, M] ............ If the arithmetic instruction is not stored or if the mode is constant calculation
mode, first prints the display contents after rounding to the specified number of
decimal places, performs addition/subtraction using the data in memory, then
stores the result in memory. If the multiplication/division instruction is stored,
executes the arithmetic instruction, rounds the result to the specified number of
decimal places, prints and display the result, adds/subtracts with the data in
memory, then stores the result to memory.
At that time, the multiplicand or divisor is stored together with the mode, constant
calculation mode. When this key is pressed immediately after the [
×] or [M+, M]
key, operation is the same as that for the [
=] key; that is, adds/subtracts using data
in memory. This key operation increments or decrements the item counter for
memory.
[M]...................... Prints or displays the intermediate result of memory calculation. In item count
mode, prints the contents of the item counter for memory before the calculation
result printing. Contents of the data register or stored arithmetic instruction are
not changed.
