BEFORE USING THE CALCULATOR

Key Notation Used in this Manual
In this manual, key operations are described as follows:

Functions that are printed in orange above the key require  to be pressed first before the key. Numbers are not shown as keys, but as ordinary numbers
Power On and Off
Press to turn the calculator on, and to turn it off.

Clearing Numbers

• Press to clear the entries except for a numerical value in the independent memory and statistical data.
•  Press to clear the number entered prior to use of function key.
• In case of one digit correction of the entered number, press ( right shift key).

Priority Levels in Calculation
This calculator performs operations according to the following prioriy:

1. Functions such as sin, %, and %
2. 3. ×,÷
3. +,-
4.  =, M+ and other calculation ending instruction
   • Calculations which are given the same priority level are executed in sequence.
   • If parentheses are used, parenthesized calculations have precedence over any other calculations.
   • Parentheses can be continuously used up to 15 times unless pending calculations exceed 4.

INITIAL SET UP

Mode Selection

Normal mode:
Used to perform arithmetic operations and function calculations. BIN, OCT, HEX, CPLX and STAT are not displayed
Binary, Octal, Decimal, or Hexadecimal system mode:

Complex number mode:
Used to perform arithmetic operations with complex numbers.
To clear this mode, press
Statistics mode:
Used to perform statistical calculations. To clear this mode,
press
When executing mode selection, statistical data will be cleared even when reselecting the same mode.

• By pressing or Automatic power off function, the mode is cleared and returned to the normal mode.

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   and any value between 0 and 9 specifies the number of decimal places in the calculation result. To clear the setting of decimal places, press .

100000÷3=

[Floating point]| | 33333.33333
[TAB setto2]| | 3333333
iSclentiic notatior]| | 333 04
S[Floating point]| | 3333333333

• I the value for floating point system does not fit in the following range, the calculator will display the result using scientific notation system 0000000001 ≤| x | ≤ 9999999999

Determination of the Angular Unit
In this calculator, the following three angular units (degrees, radians, and grads) can be specified

SCIENTIFIC CALCULATIONS

• Calculate in the normal mode.
• In each example, press to clear the display.

Arithmetic Operations

• The closing parenthesis   just before may be omitted.
• When entering only a decimal place, it is not necessary to press before .

Constant Calculations

• In the constant calculations, the addend becomes a constant. Subtraction and division are performed in the same manner. For multplication, the multipiicand 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.

Random Numbers
A pseudo-random number with three significant digits can be generated by pressing . Random number gen- eration is not possible when binary/octalhexadecimal system mode is set.
Angular Unit Conversions
Each time   are pressed, the angular unit changes in sequence.
Memory Calculations

This calculator has one independent memory (M). 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 sublracting 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 unti 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 entering multiple instructions.

Time, Decimal and Sexagesimal Calculations
This calculator performs decimal-to-sexagesimal conversion and sexagesimal-to- decimal conversion. In adition, the four basic arithmetic operations and memory calculations can be carried out using the sexagesimal system.
Notation for sexagesimal is s follows:

Note: When the calculation or conversion result is converted, a residual may occur.

Coordinate Conversions

• Before performing a calculation, select the angular unit.

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

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:

**: 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 displayed as follows:

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, negative numbers are displayed as a complement

COMPLEX NUMBER CALCULATIONS

To carry out addition, subtraction, multiplication, and division using complex numbers, press to select the complex number mode.

• Acomplex 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 in- putting 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 .
• If the complex numbers are represented as polar coordinates, press after they are input with and .

STATISTICAL CALCULATIONS

Press   to select statistics mode.
The following statistics can be obtained:

| Mean of samples (x data)
---|---
| Sample standard deviation (x data)
| Population standard deviation (x data)
| Number of samples
| Sum of samples (x data)
| Sum of squares of samples (x data)

Data Entry and Correction
Entered data are kept in memory until are pressed. Before entering new data, clear the memory contents.

Data Entry and Correction

Entered data are kept in memory until are pressed. Before entering new data, clear the memory contents.
[Data Entry]
Data
Data frequency  (To enter multiples of the same data)
[Data Correction]
Correction prior to pressing :
Delete incorrect data with .
Correction after pressing :
Reenter the data to be corrected and press .

• The number displayed after pressing   during data entry or correction is the number of samples ( ).
  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 .
  • 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, o if a mathematically illegal operation s attempted. In the case of an erfor, the display will show ‘E” An error can be cleared by pressing .

Calculation Ranges

• Within the ranges specified, this calculator is accurate to  +1 of the least significant digit of the mantissa. However, acalculation error increases in continuous calculations due to accumulation of each calculation error. (This is the same for In, 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.
