General guide
Power supply
On or Off :
T o turn the calculator on, press [ON/C]; to turn the calculator off, press
[2ndF] [OFF].
Auto power-off function :
This calculator automatically turns off it when not operated for
a pproximately 9 minutes. Power ca n be restored by pressing the [ON/C]
key again. Memory contents and the previous mode setting (ST A T, DEG,
CPLX, Base-n,…) are retained even when power is turned off or auto
power-off.
Battery replacement :
The calculator uses two alkaline button batteries GP76A(LR44) for
power. If the display becomes dim and difficult to read, the batteries should
be replaced as soon as possible.
T o re place batteries :
1) Remove the screws that hold the back cover.
2) Remove the back cover.
3) Replace the old batteries and install new ones with polarity in correct
directions.
4) Secure the screws in place, then press [ON/C] to turn the power on.
The keyboard
Many of the calculator’s keys are used to perform more than one function.
The functions marked on the keyboard are printed differently to help you find
the one you need quickly and easily.

1st functions
Those are the functions that are normally executed when you press the key.
2nd functions
The second function is printed above or to the right of the key . T o execute
2nd functions key, please press [ 2ndF ] then the corresponding key. When
you press [ 2ndF ], the “ 2ndF ” indicator shown in the display is to tell you
that you will be selecting the second function of the next key you press. If you
press [ 2ndF ] by mistake, simply press [ 2ndF ] again to remove the “ 2ndF

Display formats
The calculator can display numbers in four formats : floating point, fixed
point, scientific, and engineering.
Floating point display format
The floating point format displays numbers in decimal form, using up
to 10 digits. Any trailing zeros are truncated.
If the result of a calculation is too large to be represented in 10 digits,
the display automatically switches to scientific format. If the result of later
calculations is small enough to be displayed in 10 digits, the calculator
returns to floating point format.
(Ex.) : Set the display in floating display format.
Step : Press [ 2ndF ] [ TAB ] [ • ]
Fixed point display format
The fixed point, scientific, and engineering formats use a fixed number
of decimal places to display numbers. If more than the selected number of
decimal places is keyed, it will be rounded to the correct number of decimal
places.
DEG

(Ex.) : Fix the display at 2 decimal places, then key in 3.256

Step 2 : key in 3.256 [ = ]

On the contrary, if fewer than the selected number of decimal places
is keyed, it will be padded with trailing zero.

Step 1 : press [ 2ndF ] [ TAB ] 4
Step 2 : key in 4.23 [ = ]

Scientific display format
In Scientific display format, the number 891500 can be shown in scientific
format as 8.915 x 10 05, where 8.915 is called the mantissa and 5 is as the
exponent of 10.
(Ex.) : 7132 x 125 is displayed in scientific display format.

Besides, entry can be made in scientific notation by using the [EXP]
key after entering the mantissa.

Engineering display format
The format is similar to the scientific format, expect the mantissa can
have up to three digits left of the decimal, instead of only one, and the
exponent is always a multiple of three. It is useful for engineers to convert
units based on multiples of 10 3.
(Ex.) : Convert 15V into 15000mV (V : Volt)
Step 1 : key in 15
Step 2 : press [ ENG ] twice

Order of operations
Each calculation is performed in the following order of precedence :
1) Operation in parenthesis
2) Functions required pressing the function key before entering, for
exa mple, [ DA T A ] in ST A T mode a nd [ EXP ] key .
3) Functions required inputing values before pressing the function key,
for example, cos, sin, tan, cos–1, sin–1, tan–1, log, ln, X 2, 1/x, , ,

Correction
If you have made a mistake when entering a number (but you have not yet
pressed an arithmetic operator key), just press [ CE ] to clear the last entry
then input it again, or delete individual digits by using the backspace key
[ 00
by pressing [ON/C] to clear the calculation completely (expect clearing
memory, see page 9).

If you press the wrong arithmetic operation key, just press [ CE ] key
before entering anything else.
Accuracy and Capacity
Accuracy : 1 in 10th digit.
Capacity :
In general, every reasonable calculation is displayed up to 10 digit
mantissa, or 10-digit mantissa plus 2-digit exponent up to 10 99or integers
between – 9999999999 and 9999999999.
Numbers used as input must be within the range of the given
function. The range for each of the calculator’s functions is given in the
following pages.

Overflow / Error conditions
A symbol “ E ” are indicated on the display when any of the following
conditions occur and further calculation becomes impossible. Just press
[ ON/C ] to release those overflow or error indicator and the subsequent
calculation can then be performed.
1) When function calculations are performed with a number exceeding
the input range.
2) When a number is divided by 0.
3) When the [ ( ] key is used more than 15 times in a single expression.
4) When a result (whether intermediate or final) or accumulated total in
memory exceeds the limit. ( 9.999999999 x 10 99)
5) When more than six pending operations.

Base-n mode calculation
Converting between bases
The unit enables you to calculate in number base other than decimal.
The calculator can add, subtract, multiply, and divide binary, octal, and
hexadecimal numbers. Select the number base you want by the [ BIN],
[ OCT], [ HEX], [ DEC] keys. The BIN, OCT, and HEX indicators
show you which base you are using.(if none of the indicators appears in the
appear in the display, you are in decimal base.)
The keys active in each base is described as follows :
Binary base : [ 0 ] [ 1 ]

Negative and Complements
In binary, octal, and hexadecimal bases, the calculator represents
negative numbers using complement notation. The complement is the
result of subtracting that number from 10000000000 in that number’s
base by pressing [ +/– ] key in non-decimal bases.

Complex numbers calculation
Select the complex numbers mode by pressing [ CPLX ] key and
make sure “ CPLX ” indicator appears on the display. The calculator
enables you to add, subtract, multiply, and divide complex numbers.
Complex numbers are generally represented as a + b i, where a is a
real and b is imaginary.

Viewing statistics data
Pressing [ DAT A ] or [ = ] key under ED mode can view the statistics data
you have entered. The difference between [ DA T A ] a nd [ = ] is the item of
the data entry a ppears 1.5 sec. before the value by [ DATA ], the value
appears immediately without the item by [ = ].
(Ex.2) : View the statistics data based on Ex. 1.
Step 0 : Press [ 2ndF ] [ EDIT ] to enter ED mode.
(Method 1) :
Step 1 : Press [ DA T A ] once to view the f irst data.

Adding a data entry
(Ex.3) : Add data 9 = 10 to Ex.1
Step 1 : Press [ DATA ] 10
Step 2 : The calculator updates the statistics as you enter
data. You can then recall all varia ble statistics to
get the following result : = 6.56, n = 9.00, S = 2.

retained, for example, delete 7 based on Ex.1.
Step 1 : Press 7 [ 2ndF ] [ DEL ]

Weighted data entry method
Instead of entering directly each data, when often several item of data
have the same value, you can enter the value and the number of occurrences up to 255. The data based on Ex.1 can be rewritten and entered as
follow :
V alue Number of occurrences Alternative method
21 [ DATA ] 2
5 4 [ DA TA ] 5 [ x ] 4
9 3 [ DA TA ] 9 [ x ] 3
, where data 1 = 2, data 2~5 = 5, data 6~8 = 9.
Under ED mode, when you continue choosing a value from data 2~5 and
correcting it as 33, the permutation among those data will be changed as
data 1 = 2, data 2~4 = 5, data 5 = 33, data 6~8 = 9, where the new value 33
is inserted after data 4 = 5.
(Note) : A “FULL” is indicated when any of the following conditions occur
and further data entry becomes impossible. Just pressing any
key can clear the indicator. The previous data entries are still
retained unless exiting ST A T mode.
1) If the times of data entry by [ DA T A ] is more tha n 80
2) The number of occurrences is more than 255
3) n 20400 (n = 20400 appears when the times of data entry by
[ DA TA ] are up to 80 a nd the number of occurrences for e a ch
value are all 255, i.e. 20400 = 80 x 255.)
