Operational Notes
To ensure trouble-free operation, please observe the fol-
lowing points:
1. Do not carry the calculator in the back pocket of slacks
or trousers.
2. Do not subject the calculator to extreme temperatures.
3. Do not drop it or apply excessive force.
4. Clean only with a soft, dry cloth.
5. Do not use or store the calculator where fluids can
splash onto it.
Press the RESET switch only in the following cases:

If the value of mantissa does not fit within the range
±0.000000001 – ±9999999999, the display changes to
scientific notation. The display mode can be changed ac-
cording to the purpose of the calculation.

When performing calculations using constants, constants
will be displayed as K.

BEFORE USING THE CALCULATOR
Key Notation Used in this Manual
In this manual, key operations are described as follows:
2 To specify x 2 :
x @ L
To specify Exp: E
E
Functions that are printed in yellow 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 N to turn the calculator on, and @ F to
turn it off.

Random Numbers
A pseudo-random number with three significant digits can
be generated by pressing @ ` =. To generate
the next random number, press =. You can perform
this function in the normal and statistics modes.
• Random numbers use memory Y. Each random number
is generated on the basis of the value stored in memory
Y (pseudo-random number series).

See page 9 for additional reference.
Editing the Equation
• Press < or > to move the cursor. You can also
return to the equation after getting an answer by press-
ing > (<).
• If you need to delete a number, move the cursor to the
number you wish to delete then press d.
The number under the cursor will be deleted.
• If you need to insert a number, move the cursor to the
place immediately after where you wish to insert the
number then enter the number.
Priority Levels in Calculation
This calculator performs operations according to the fol-
lowing priority:

Memory Calculations
This calculator has two temporary memories (X and Y),
one independent memory (M) and one last answer
memory. Independent memory and temporary memories
are only available in the normal mode.
[Temporary memories (X and Y)]
A stored value can be recalled as a value or variable for
the use in equations.
• In case you store an infinite decimal in the memory,
recall it as a variable to obtain accurate answers.
Ex.) 1 / 3 O Y (0.3333...is stored to Y)
3 * R Y =
0.999999999
3 * @ K Y =
1.
[Independent memory (M)]
In addition to all the features of temporary memories, a
value can be added to or subtracted from an existing
memory value.
[Last answer memory (ANS)]
The calculation result obtained by pressing = or any
other calculation ending instruction is automatically stored
in the last answer memory.
Note:
Calculation results from the functions indicated below are
automatically stored in memories X or Y. For this reason,
when using these functions, be careful with the use of
memories X and Y.
• Random numbers .................. Y memory
• r , xy ............................... X memory, Y memory
Temporary memories and last answer memory are cleared
even when the same mode is reselected.
See page 4 for additional reference.

INITIAL SETUP
Mode Selection
Normal mode: @m0
Used to perform arithmetic operations and function calcu-
lations.
Statistics mode: @m1
Used to perform statistical calculations.
When executing mode selection, temporary memories, sta-
tistical data and last answer memory will be cleared even
when reselecting the same mode.
Selecting the Display Notation and Decimal
Places
The calculator has four display notation systems for dis-
playing calculation results. When FIX, SCI, or ENG sym-
bol is displayed, the number of decimal places can be set
to any value between 0 and 9. Displayed values will be
reduced to the corresponding number of digits.
