Key Descriptions
&
Advances the paper.
2
Clears the entire pending operation except the memory or
the grand total.
O
Changes the sign (
+
or
–
) of the displayed number.
>
Interprets the number in the display as a percentage.
I
Clears an entry or an error or overflow.
=
Computes the percentage of change between two values.
(The price increase from 9.75 to 11.25 is 1.50, and the
percentage increase is 15.38%)
#
Calculates the selling price and profit or loss amount on an item.
(
Removes the last digit entered in the display.
4
Prints a reference number or date without affecting calculations.
!
Adds the stored tax rate to the value in the display.
"
Subtracts the stored tax rate from the value in the display.
/
Pressed once, displays and prints the grand total of all
totals. Pressed twice, clears the grand total. This is active
only if PRINTER = GT.
:
Displays and prints the total, but does not clear the total.
E
Displays and prints the total and clears the total. Also
resets the item counter (IC) to zero.
0
Displays and prints the value in memory and clears the
memory. Also clears Mfrom the display and resets the
memory item counter to zero.
3
;
Displays and prints the current total in memory but does
not clear the memory.
F
Subtracts the displayed value from memory. If a
multiplication or division operation is pending,
F
completes it and subtracts the result from memory.
N
Adds the displayed value to memory. If a multiplication or
division operation is pending,
N
completes it and adds
the result to memory.
Using Decimals (DECIMAL Switch)
+
Lets you add and subtract numbers without entering the
decimal point (key in 5321 to enter 53.21).
F
The number of decimal places varies based on the result.
0,2,3,4,6
Sets the number of decimal places to 0, 2, 3, 4, or 6.
Rounding (ROUND Switch)
:
Results are rounded down (if DECIMAL
= 1
, 2.39 rounds to 2.3).
5/4
Results are rounded up or down, depending on the value and
decimal setting (if DECIMAL =
2
, 2.349 rounds to 2.35).
9
Results are rounded up (if DECIMAL
= 1
, 2.33 rounds to 2.4).
Entering a Tax Rate (TAX Switch)
SET Lets you enter a tax rate to perform tax calculations.
CALC Stores the tax rate.
Printing (PRINTER Switch)
OFF Calculations are displayed but not printed.
ON Calculations are displayed and printed.
IC Both the printer and item counter are active. To clear the
item counter, press
E
or
0
.
GT Accumulates a running grand total of all calculations you
perform until you clear the grand total. To print a grand
total, press
/
. To clear the grand total, press
/
again.
Positive entries and results are printed in black; negative entries and
results are printed in red.

Clearing Errors and Overflows
Correcting Entry Errors
If you have not pressed an operation key:
•
To clear an incorrect entry, press
I
. You can then enter the
correct value and continue with your calculation.
•
To clear the last digit, press
(
.
If you have pressed an operation key:
•
To cancel an incorrect entry, press the opposite operation key. This
applies only to calculations involving
9
,
.
,
N,
or
F
.
Error and Overflow Conditions and Indicators
If you divide by zero or calculate a selling price using a margin of 100%, an
error occurs. The calculator prints ERROR
0 .*
and displays Eand
0
.
An overflow occurs if you calculate a result with too many digits for the
calculator to display or print. When this occurs, the calculator:
•
Displays Eand the first 12 digits of the result with a decimal point 11
places to the left of its correct position.
•
Prints ERROR and the first 12 digits of the result with the decimal
shifted 11 places to the left of its correct position.
To clear an error or overflow,
press
2
. The memory is not cleared
unless the error or overflow occurred in a memory calculation.
