INITIAL SETUP
Mode Selection
Normal mode: ��
Used ta perform arithmetic operations and function calculations.
Statistics mode: ��
Used to periorm statistical calculations.
When executin g mode selection, tempora memories, st atistical data and
last answer memory will be cleared even when reselectin g the same mode.
Selecting the Display Notation and Decimal Places
The calculator has four display notation systems for displaying calculation
res ults. When FIX, SCI, or ENG symbol is displayed, the number of decimal
plac es can be set ta any value betwee n O and 9.
Displayed values will be reduced ta the corresponding number of digits.

SCIENTIFIC CALCULATIONS
• Press � � ta select the normal mode.
• ln each example, press to clear the display.
• If the FIX, SCI, or ENG indicator is displayed, clear the indicator by
pressing� �-
Arithmetic Operations/Constant Calculations
[1]
• The closi ng parenthes is just before D or� may be omitted.
• The addend becomes a constant. Subtraction and division are
performed in the same manner. The multiplicand becomes a constant.
• When performing calculations usi ng const ants, constants will be displayed
as K.
Functions
[
2
]
Refer ta the calculation examples of each function.
Random Numbers
A pseudo-random number with three significant digits can be generated
by press ing � � �- To generate the next random number, press
�-Vou can periorm this function in the normal and statistics modes.
• Random numbers use memory V. Each random number is generated on the
basis of the value stored in memo V (pseudo-random number series).
Angular Unit Conversions
[3]
Each lime � � are presse d, the angular unit changes in se quence.
Memo Calculations [4]
This calculator has four temporary memories (X, V, r, 0), one
indepen dent memory (M) and one last answer memo (ANS).
lndependent memory and temporary memories are only available in the
normal mode.
[Temporary memories (X, Y, r, 0)]
Press and a variable key to store a value in memory.
Press and a variable key to recall the value from that memory.
To place a variable in an equation, press �� and a variable key.
Use of or � � will recall the value stored in memo using up
ta 14 digits.
[lndependent memory (M)]
ln addition ta all the features of temporary memories, a value can be
added ta or subtracted from an existing memo value.
[Last answer memory (ANS)]
The calculation result obtained by pressing � or any other calculation
ending instruction is automatically stored in the last answer memo.
Chain Calculations
[5]
This calculator allows the previous calculation result ta be used in the
following calculation. The previous calculation result will not be recalled
after entering multiple instructions.
Fraction Calculations [6]
This calculator performs arithmetic operations and memory calculations
using fractions, and conversion between a decimal number and a
fraction.
• If the nu mber of digits ta be displayed is greater than 10, the number is
converted ta and displayed as a decimal number.
Time, Decimal and Sexagesimal Calculations
[7]
Conversion bet ween decimal and se xages imal numbers can be peormed.
ln addition, the four ba sic arithmetic op erations and memory calculations can
be carried out using the sexagesimal system.

Statistical Calculation Formulas
[1
0
]
ln the statistical calculation formulas, an error will occur when:
• the absolute value of the intermediate result or calculation result is
equal ta or greater than 1 x 10
100
.
• the denominator is zero.
• an attempt is made ta 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.
When an errer occurs, pressing� (or ) automatically moves
the cursor back to the place in the equation where the errer occurred.
Edit the equation or press �to clear the equation.
Error Codes and Error Types
Syntax errer (Error 1 ):
• An attempt was made ta pe orm an invalid operation.
Ex. 2��
Calculation error (Error 2):
The absolute value of an intermediate or final calculation result
equals or exceeds 1
o
100
.
An attempt was made ta divide by O.
The calculation ranges were excee ded while peorming calculations .
Depth errer (Errer 3):
The available nu mber of buffers was excee ded. (There are 10 buffers*
for numeric values and 24 buffers for calculation instructions).
"5 buffers in STAT mode.
Equation tao long (Error 4):
• The equation exceeded ils maximum input buller (159 characters).
An equ ation must be shorter than 15
9
characters.
Calculation Ranges [11]
• Within the ranges specified below, this calculator is accurate ta ±1 in the
least significant digit of the mantissa. When peoring continuous calculations
(including chain calculations), err
o
rs accumulate leading to reduced accura.
(This is the same for , x-y, &, ln, etc., where continuous calculations are
performed internally.)
• Calculation ranges

BATTERY REPLACEMENT
Notes on Batte Replacement
lmproper handling of batteries can cause electrolyte leakage or explosion.
Be sure ta obsee the following handling rules:
• Make sure the new battery is the correct type.
• When installing, orie nt the bae properly as indicate d in the calculator.
• The bae is facto-installed before shipment, and may be exhausted
before il reaches the service life stated in the specifications.
When to Replace the Bae
If the display has poor contrast or nothing appears on the display even
when � is pressed in dim lighting, il is lime ta replace the battery.
Caution
• An exhausted batte le in the calculator may leak and damage the calculator.
