Operational Notes

• Do not carry the calculator around in your back pocket, as

it may break when you sit down. The display is made of

glass and is particularly fragile.

• Keep the calculator away from extreme heat such as on a

car dashboard or near a heater, and avoid exposing it to

excessively humid or dusty environments.

• Since this product is not waterproof, do not use it or store

it where fluids, for example water, can splash onto it.

Raindrops, water spray, juice, coffee, steam, perspiration,

etc. will also cause malfunction.

• Clean with a soft, dry cloth. Do not use solvents or wet

cloth.

• Do not drop it or apply excessive force.

• Never dispose of batteries in a fire.

• Keep batteries out of the reach of children.

• This product, including accessories, may change due to

Determination of the Angular Unit

In this calculator, the following three angular units (degrees,

radians, and grads) can be specified.

Press G

Selecting the Display Notation and Decimal Places

•When calculation result is displayed in the floating point

system, pressing displays the result in the scientific∞

notation system.

Pressing ∞ once more displays the result again in the

floating point system.

•Pressing @i and any value between 0 and 9 speci-

fies the number of decimal places in the calculation result.

To clear the setting of decimal places, press @ i

SCIENTIFIC CALCULATIONS

•Calculate in the normal mode.

•In each example, press ª to clear the display.

Arithmetic Operations

•The closing parenthesis ) = ; just before or

may be omitted.

•When entering only a decimal place, it is not necessary to

press 0 before ..

Random Numbers

A pseudo-random number with three significant digits can be

generated by pressing @ ` . Random number gen-

eration is not possible when binary/octal/hexadecimal sys-

tem mode is set.

Angular Unit Conversions

Each time are pressed, the angular unit changes@ g

in sequence.

Memory Calculations

This calculator has one independent memory (M). It is avail-

able in the normal mode and binary, octal, hexadecimal

system mode.

•The independent memory is indicated by the three keys:

O R ;, , .

Before starting a calculation, clear the memory by press-

ing ª and O.

•A value can be added to or subtracted from an existing

memory value. When subtracting a number from the

memory, press ± and ;.

•The contents of the memory are retained even when the

calculator is turned off. A value stored in memory will thus

remain until it is changed or until the batteries run out.

Chain Calculations

This calculator allows the previous calculation result to be

used in the following calculation.

The previous calculation result will not be recalled after en-

tering multiple instructions.

Time, Decimal and Sexagesimal Calculations

This calculator performs decimal-to-sexagesimal conversion

and sexagesimal-to-decimal conversion. In addition, the four

basic arithmetic operations and memory calculations can be

carried out using the sexagesimal system.

Notation for sexagesimal is as follows:

123.404080

degree second

minute

Note: When the calculation or conversion result is con-

verted, a residual may occur.

Constant Calculations

•In the constant calculations, the addend becomes a con-

stant. Subtraction and division are performed in the same

manner. For multiplication, the multiplicand becomes a

constant.

Functions

•Refer to the calculation examples of each function.

•For most calculations using functions, enter numerical

values before pressing the function key.

STATISTICAL CALCULATIONS

Press @ Æ to select statistics mode.

The following statistics can be obtained:

x xMean of samples ( data)

sx Sample standard deviation (x data)

x xPopulation standard deviation ( data)

nNumber of samples

x xSum of samples ( data)

x2Sum of squares of samples (x data)

Data Entry and Correction

Entered data are kept in memory until or @ Æ F

are pressed. Before entering new data, clear the memory

contents.

[Data Entry]

frequency

k (To enter multiples of the same

data)

[Data Correction]

Correction prior to pressing k:

Delete incorrect data with ª.

Correction after pressing k:

Reenter the data to be corrected and press @ J .

•The number displayed after pressing k @ J or

during data entry or correction is the number of samples

(n).

Statistical Calculation Formulas

In the statistical calculation formulas, an error will occur when:

•the absolute value of the intermediate result or calculation

result is equal to or greater than 1 × 10

100.

•the denominator is zero.

•an attempt is made to take the square root of a negative

number.

BINARY, OCTAL, DECIMAL, AND

HEXADECIMAL OPERATIONS (N-BASE)

This calculator can perform the four basic arithmetic opera-

tions, calculations with parentheses and memory calcula-

tions using binary, octal, decimal, and hexadecimal num-

bers.

When performing calculations in each system, first set the

calculator in the desired mode before entering numbers.

It can also perform conversions between numbers expressed

in binary, octal, decimal and hexadecimal systems.

Conversion to each system is performed by the following

keys:

Ï ê : Converts to the binary system. “ ”BIN appears.

Ï î : Converts to the octal system. “ ”OCT appears.

Ï ì : Converts to the hexadecimal system. “ ”HEX

appears.

Ï í : Converts to the decimal system. “ ”BIN , “ ”OCT ,

and HEX“ ” disappear from the display.

Conversion is performed on the displayed value when these

keys are pressed.

Note: In this calculator, the hexadecimal numbers A – F are

entered by pressing E, , , , Ñ ⁄ ´ I,

and l, and displayed as follows:

A → å, B → ∫, C → ç, D → ∂, E → é, F → ƒ

In the binary, octal, and hexadecimal systems, fractional

parts cannot be entered. When a decimal number having a

fractional part is converted into a binary, octal, or hexadeci-

mal number, the fractional part will be truncated. Likewise,

when the result of a binary, octal, or hexadecimal calculation

includes a fractional part, the fractional part will be trun-

cated. In the binary, octal, and hexadecimal systems, nega-

tive numbers are displayed as a complement.

A B C D E

COMPLEX NUMBER CALCULATIONS

To carry out addition, subtraction, multiplication, and division

using complex numbers, press to select the com-@π

plex number mode.

•A complex number is represented in the a + bi format. The

“ ” “ ”a is the real part while the bi is the imaginary part.

When inputting the real part, after inputting the number

press a. When inputting the imaginary part, after in-

putting the number press . To obtain the result pressb

•Immediately after completing calculation, you can recall

the value of the real part with , and the value of thea

imaginary part with b.

•If the complex numbers are represented as polar coordi-

nates, press after they are input with @} a

and b.

ERROR AND CALCULATION RANGES

Errors

An error will occur if an operation exceeds the calculation

ranges, or if a mathematically illegal operation is attempted.

In the case of an error, the display will show “ ”E .

An error can be cleared by pressing ª.

Calculation Ranges

•Within the ranges specified, this calculator is accurate to

±1 of the least significant digit of the mantissa. However, a

calculation error increases in continuous calculations due

to accumulation of each calculation error. (This is the

same for yx, x¿ ,

, etc., where continuous calculations

are performed internally.)

Additionally, a calculation error will accumulate and

become larger in the vicinity of inflection points and

singular points of functions.

•Calculation ranges

±10

-99 ~ ±9.999999999×1099 and 0.

If the absolute value of an entry or a final or intermediate

result of a calculation is less than 10–99, the value is consid-

ered to be 0 in calculations and in the display.
