in sequence.

Memory Calculations

(5)

This calculator has one independent memory. It is available in
the normal mode and binary, octal, hexadecimal system mode.
• The independent memory is indicated by the three keys:

;

Before starting a calculation, clear the memory by pressing

and

• 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

(6)

This calculator allows the previous calculation result to be
used in the following calculation.
The previous calculation result will not be recalled after enter-
ing multiple instructions.

Time, Decimal and Sexagesimal Calculations

(7)

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

Statistical Calculation Formulas

(n: Number of samples)

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

100

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

number.

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

Calculation Ranges

• Within the ranges specified below, this calculator is accu-

rate to ±1 in the least significant digit of the mantissa. When
performing continuous calculations (including chain calcu-
lations), errors accumulate leading to reduced accuracy.

• Calculation ranges

±10

-99

~ ±9.999999999

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.

BINARY, OCTAL, DECIMAL, AND
HEXADECIMAL OPERATIONS (N-BASE)

(9)

This calculator can perform the four basic arithmetic opera-
tions, calculations with parentheses and memory calculations
using binary, octal, decimal, and hexadecimal numbers.
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:

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

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

: Converts to the hexadecimal system. “HEX”

appears.

: 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

⁄

and

, and displayed as follows:

→

, B

→

∫

, C

→

, D

→

∂

, E

→

, F

→

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

COMPLEX NUMBER CALCULATIONS

(10)

To carry out addition, subtraction, multiplication, and division
using complex numbers, press

@π

to select the com-

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

. When inputting the imaginary part, after inputting the

number press

. To obtain the result press

• Immediately after completing calculation, you can recall the

value of the real part with

, and the value of the

imaginary part with

BATTERY REPLACEMENT

Notes on Battery Replacement

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 (LR44).
• 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
specifications.

When to Replace the Batteries

If the display has poor contrast, the batteries require replace-
ment.
