Each time @gare pressed, the angular unit changes 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:

O, R, ;.

Before starting a calculation, clear the memory by pressing ªand 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

(6)

This calculator allows the previous calculation result to be used in the following calculation.

The previous calculation result will not be recalled after entering 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:

BINARY, OCTAL, DECIMAL, AND

HEXADECIMAL OPERATIONS (N-BASE)

(9)

This calculator can perform the four basic arithmetic operations, 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:

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

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

Ïì : Converts to the hexadecimal system. “HEX”

appears.

Ïí : 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

A B C D E

entered by pressing E, Ñ, ⁄, ´, I,

F

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 hexadecimal 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 truncated. In the binary, octal, and hexadecimal systems, negative numbers are displayed as a complement.

COMPLEX NUMBER CALCULATIONS

(10)

To carry out addition, subtraction, multiplication, and division using complex numbers, press @πto select the complex 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 inputting the number press b. To obtain the result press =.

•Immediately after completing calculation, you can recall the value of the real part with a, and the value of the imaginary part with b.

•If the complex numbers are represented as polar coordinates, press @}after they are input with aand b.

STATISTICAL CALCULATIONS				(11)
Press @Æto select statistics mode.
The following statistics can be obtained:
	x		Mean of samples (x data)
sx			Sample standard deviation (x data)
σ x			Population standard deviation (x data)
n			Number of samples
Σ x			Sum of samples (x data)
Σ x2			Sum of squares of samples (x data)

Entered data are kept in memory until @Æor F are pressed. Before entering new data, clear the memory contents.

[Data Entry]

Data k

[Data Correction]

Correction prior to pressing k: Delete incorrect data with ª.

Correction after pressing k:

Press @Jto delete the latest entry.

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 × 10100.

•the denominator is zero.

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

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 replacement.

Caution

•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.

•Batteries must be replaced only with others of the same type.

•Do not throw batteries into a fire as they may explode.

Replacement Procedure

1.Turn the power off by pressing F.

2.Loosen both screws and remove the battery cover. (Fig. 1)

Fig. 1

Fig. 2

3.Remove the used batteries then replace with two fresh batteries with the positive sides (+) facing up. (Fig. 2)

4.Replace the battery cover and screws.

5.Press ª.

•Make sure that the display appears as shown below. If the display does not appear as shown, reinstall the batteries and check the display once again.

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 below, this calculator is accurate to ±1 in the least significant digit of the mantissa. When performing continuous calculations (including chain calculations), errors accumulate leading to reduced accuracy.

•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 considered to be 0 in calculations and in the display.
