Improper handling of batteries can cause electrolyte leakage or
explosion. Be sure to observe the following handling rules:
• Replace both batteries at the same time.
• Do not mix new and old batteries.
• Make sure the new batteries are the correct type.
• When installing, orient each battery properly as indicated in the

calculator.

• Batteries are factory-installed before shipment, and may be

exhausted before they reach the service life stated in the speci-
fications.

Notes on erasure of memory contents
When the battery is replaced, the memory contents are erased.
Erasure can also occur if the calculator is defective or when it is
repaired. Make a note of all important memory contents in case
accidental erasure occurs.

If the display has poor contrast or nothing appears on the display
even when ª  is pressed in dim lighting, it is time to replace
the batteries.

• Fluid from a leaking battery accidentally entering an eye could

result in serious injury. Should this occur, wash with clean
water and immediately consult a doctor.

• Should fluid from a leaking battery come in contact with your

skin or clothes, immediately wash with clean water.

• If the product is not to be used for some time, to avoid damage

to the unit from leaking batteries, remove them and store in a
safe place.

• Do not leave exhausted batteries inside the product.
• Do not fit partially used batteries, and be sure not to mix

batteries of different types.

• Keep batteries out of the reach of children.
• Exhausted batteries left in the calculator may leak and damage

the calculator.

• Explosion risk may be caused by incorrect handling.
• Do not throw batteries into a fire as they may explode.

1. Turn the power off by pressing @F.
2. Remove the two screws. (Fig. 1)
3. Slide the battery cover slightly and lift it to remove.

Calculation can be executed in the normal mode (excluding N-
base) using the following 9 types of prefixes.

Calculation results are internally obtained in scientific notation
with up to 14 digits for the mantissa. However, since calculation
results are displayed in the form designated by the display nota-
tion and the number of decimal places indicated, the internal
calculation result may differ from that shown in the display. By
using the modify function, the internal value is converted to match
that of the display, so that the displayed value can be used
without change in subsequent operations.

The x value can be found that reduces an entered equation to “0”.
• This function uses Newton's method to obtain an approxima-

tion. Depending on the function (e.g. periodic) or start value, an
error may occur (Error 2) due to there being no convergence to
the solution for the equation.

• The value obtained by this function may include a margin of

error. If it is larger than acceptable, recalculate the solution
after changing ‘Start’ and dx values.

• Change the ‘Start’ value (e.g. to a negative value) or dx value

(e.g. to a smaller value) if:
• no solution can be found (Error 2).
• more than two solutions appear to be possible (e.g. a cubic

equation).

• to improve the arithmetic precision.

• The calculation result is automatically stored in the X memory.

If you have to find a value consecutively using the same formula,
such as plotting a curve line for 2x

2

 + 1, or finding the variable for

2x + 2y =14, once you enter the equation, all you have to do is to
specify the value for the variable in the formula.

Four display notation systems are used to display calculation re-
sults: Floating point; Fixed decimal point; Scientific notation; and
Engineering notation.
• When the FIX, SCI, or ENG symbol is displayed, the number of decimal

places (TAB) can be set to any value between 0 and 9. Displayed
values will be reduced to the corresponding number of digits.

[Setting the Floating Point Numbers System in Scientific Notation]
Two settings are used to display a floating point number: NORM1
(default setting) and NORM2. A number is automatically displayed
in scientific notation outside a preset range:
• NORM1: 0.000000001 

≤

• Press m0 to select the normal mode.
• In each example, press ª to clear the display. If the FIX, SCI,

or ENG indicator is displayed, clear the indicator by selecting
‘NORM1’ from the SET UP menu.

• The closing parenthesis ) just before = or ; may be

omitted.

• In constant calculations, the addend becomes a constant. Sub-

traction and division are performed in the same manner. For
multiplication, the multiplicand becomes a constant.

• In the constants calculations, constants will be displayed as K.

• Refer to the calculation examples of each function.
• Before starting calculations, specify the angular unit.

Differential and integral calculations are only available in the nor-
mal mode. For calculation conditions such as the x

 value in differ-

ential calculation or the initial point in integral calculation, only
numerical values can be entered and equations such as 2

2

 cannot

be specified. It is possible to reuse the same equation over and
over again and to recalculate by only changing the conditions with-
out re-entering the equation.
• Performing a calculation will clear the value in the X memory.
• When performing a differential calculation, enter the formula first and

then enter the x value in differential calculation and the minute interval
(dx). If a numerical value is not specified for minute interval, 

≠0 will be





×10

–5

 and 

=0 will be 10

–5

 from the value of the numeric derivative.

• When performing an integral calculation, enter the formula first

and then enter a range of integral (a, b) and subintervals (n). If a
numerical value is not specified for subintervals, calculation will
be performed using n=100.

Since differential and integral calculations are performed based on
the following equations, correct results may not be obtained, in
certain rare cases, when performing special calculations that con-
tain discontinuous points.

Integral calculation (Simpson’s rule):

S=—h{

ƒ(a)+4{ƒ(a+h)+ƒ(a+3h)+······+ƒ(a+(N–1)h)}

+2{

ƒ(a+2h)+ƒ(a+4h)+······+ƒ(a+(N–2)h)}+f(b)}

Differential calculation:

[When performing integral calculations]
Integral calculations, depending on the integrands and subintervals
included, require longer calculation time. During calculation, “Calculat-
ing!” will be displayed. To cancel calculation, press ª. Note that
there will be greater integral errors when there are large fluctuations in

the integral values during
minute shifting of the inte-
gral range and for periodic
functions, etc., where posi-
tive and negative integral
values exist depending on
the interval.
For the former case, divide
integral intervals as small
as possible. For the latter
case, separate the positive and negative values. Following these
tips will allow results of calculations with greater accuracy and will
also shorten the calculation time.

The Random function has four settings for use in the normal, statis-
tics, matrix and list modes. (This function cannot be selected while
using the N-Base function.) To generate further random numbers in
succession, press ®. Press ª to exit.
• The generated pseudo-random number series is stored in memory

Y. Each random number is based on a number series.

[Random Numbers]
A pseudo-random number, with three significant digits from 0 up to
0.999, can be generated by pressing @`0®.
[Random Dice]
To simulate a die-rolling, a random integer between 1 and 6 can be
generated by pressing @`1®.
[Random Coin]
To simulate a coin flip, 0 (head) or 1 (tail) can be randomly gener-
ated by pressing @`2®.
[Random Integer]
An integer between 0 and 99 can be generated randomly by press-
ing @`3®.

use of the ª key.

Arithmetic operations and memory calculations can be performed
using fractions, and conversion between a decimal number and a
fraction.
• If the number of digits to be displayed is greater than 10, the

number is converted to and displayed as a decimal number.

Conversions can be performed between N-base numbers. The four
basic arithmetic operations, calculations with parentheses and
memory calculations can also be performed, along with the logical
operations AND, OR, NOT, NEG, XOR and XNOR on binary, pental,
octal and hexadecimal numbers.
Conversion to each system is performed by the following keys:
@ê (“ ” appears.), @û (“ ” appears.), @î
(“ ” appears.), @ì (“ ” appears.), @í (“ ”, “ ”, “ ”
and “ ” disappear.)

• The result will be displayed by pressing ® after entering all

coefficients. When there are more than 2 results, the next solu-
tion will be displayed.

• When the result is an imaginary number, “xy” symbol will appear.

The display can be switched  between imaginary and real parts
by pressing @≠.

• The results obtained by this function may include a margin of error.

To carry out addition, subtraction, multiplication, and division using
complex numbers, press m3 to select the complex number
mode.
Results of complex number calculations are expressed in two modes:
Q

@}: Rectangular coordinate mode (xy appears.)

W

@{: Polar coordinate mode (r

Q Rectangular coordinates

x-coordinate + y-coordinate Ü
or 

x-coordinate + Ü y-coordinate

W Polar coordinates

r Ö 

θ

r: absolute value

θ: argument

• On selecting another mode, the imaginary part of any complex

number stored in the independent memory (M) will be cleared.

• A complex number expressed in rectangular coordinates with the

y-value equal to zero, or expressed in polar coordinates with the
angle equal to zero, is treated as a real number.

• Press ∑0 to return the complex conjugate of the speci-

fied complex number.

This function enables the saving of up to 4 matrices (4 rows x 4
columns) for calculations. Press m4 to enter the matrix mode.

In the binary, pental, octal, and hexadecimal systems, fractional
parts cannot be entered. When a decimal number having a frac-
tional part is converted into a binary, pental, octal, or hexadeci-
mal number, the fractional part will be truncated. Likewise, when
the result of a binary, pental, octal, or hexadecimal calculation
includes a fractional part, the fractional part will be truncated. In
the binary, pental, octal, and hexadecimal systems, negative num-
bers are displayed as a complement.

Conversion between decimal and sexagesimal numbers can be
performed, and, while using sexagesimal numbers, conversion to
seconds and minutes notation. The four basic arithmetic opera-
tions and memory calculations can be performed using the
sexagesimal system. Notation for sexagesimal is as follows:

• Before performing a calculation, select the angular unit.

• The calculation result is automatically stored in memories X

and Y.
• Value of r or x: X memory

• Value of 

θ or y: Y memory

See the quick reference card and the English manual reverse side.
A constant is recalled by pressing ß followed by the number
of the physical constant designated by a 2-digit number.
The recalled constant appears in the display mode selected with
the designated number of decimal places.
Physical constants can be recalled in the normal mode (when not
set to binary, pental, octal, or hexadecimal), statistics mode, equa-
tion mode, matrix mode and list mode.
Note: Physical constants and metric conversions are based either

on the 2002 CODATA recommended values or 1995 Edi-
tion of the “Guide for the Use of the International System of
Units (SI)” released by NIST (National Institute of Stand-
ards and Technology) or on ISO specifications.

See the quick reference card and the English manual reverse side.
Unit conversions can be performed in the normal mode (when not
set to binary, pental, octal, or hexadecimal), statistics mode, equa-
tion mode, matrix mode and list mode.
