INTRODUCTION
About the calculation examples (including some formulas
and tables), refer to the second half of this manual.
After reading this manual, store it in a convenient location for
future reference.
Note: Some of the models described in this manual may not be
available in some countries.
Operational Notes
• Do not carry the calculator around in your back pocket, as it
may break when you sit down. The display is made of glass
and is particularly fragile.
• Keep the calculator away from extreme heat such as on a
car dashboard or near a heater, and avoid exposing it to
excessively humid or dusty environments.
• Since this product is not waterproof, do not use it or store it
where fluids, for example water, can splash onto it. Raindrops,
water spray, juice, coffee, steam, perspiration, etc. will also
cause malfunction.
• Clean with a soft, dry cloth. Do not use solvents or a wet cloth.
Avoid using a rough cloth or anything else that may cause
scratches.
• Do not drop it or apply excessive force.
• Never dispose of batteries in a fire.
• Keep batteries out of the reach of children.
• For the sake of your health, try not to use this product for long
periods of time. If you need to use the product for an extended
period, be sure to allow your eyes, hands, arms, and body
adequate rest periods (about 10–15 minutes every hour).

Indicates that H has been pressed and the hyperbolic
functions are enabled. If @ > is pressed, the
symbols "2ndF HYP" appear, indicating that inverse
hyperbolic functions are enabled.
ALPHA: Appears when ; is pressed, indicating that the
functions shown in the same color as ; are enabled.
Appears when x or t is pressed, and entry (recall)
of memory contents can be performed.
FIX/SCI/ENG/N1/N2: Indicates the notation used to display a value
and changes by SET UP menu. N1 is displayed on-screen
as "NORM1", and N2 as "NORM2".
DEG/RAD/GRAD: Indicates angular units.
BUSY: Appears during the execution of a calculation.
17ASC76E1
W-VIEW: Indicates that the WriteView editor is selected.
M: Indicates that a numerical value is stored in the
independent memory (M).
BEFORE USING THE CALCULATOR
Press j to turn the calculator on. The data that was on-screen
when the power was turned off will appear on the display.
Press @ o to turn it off.

• Functions that are printed in gray adjacent to the keys are
effective in specific modes.
• The multiplication operator " " is differentiated from the letter "X"

• In certain calculation examples, where you see the o symbol,
the key operations and calculation results are shown as they
would appear in the Line editor.
• In each example, press j to clear the display first. Unless
otherwise specified, calculation examples are performed in the
WriteView editor (J 2 0 0) with the default display
settings.

Selecting the display notation and decimal places
Two settings of Floating point (NORM1 and NORM2), Fixed decimal
point (FIX), Scientific notation (SCI), and Engineering notation (ENG).
• When J 1 0 (FIX) or J 1 2 (ENG) is
pressed, the number of decimal places (TAB) can be set to any
value between 0 and 9.
• When J 1 1 (SCI) is pressed, the number of significant
digits can be set to any value between 0 and 9. Entering 0 will set
a 10-digit display.
Setting the floating point number system in scientific notation
NORM1 (the default) and NORM2. A number is automatically
displayed in scientific notation outside a preset range:
NORM1 (J 1 3): 0.000000001
≤
NORM2 (J 1 4): 0.01
Selecting the editor and setting the answer display
This calculator has the following two editors in NORMAL mode:
WriteView and Line.
Set the display format for numerical calculation results in WriteView
editor.
The WriteView editor
p
EXACT(a/b,r, ) J 2 0 0 (default)
APPROX.
J 2 0 1
The Line editor
J 2 1
Notes:
p
• When "EXACT(a/b,r, )" is set, results will appear in fraction
format or irrational number format (including
display is possible.
• When "APPROX." is set, results will be decimal display or
fraction display, and will be not shown in irrational number format
p
(including and r).
• Press U to change the calculation results to another format
that can be displayed.
Adjusting the display contrast
Press J 3, then + or & to adjust the contrast. Press
j to exit.
Insert and overwrite entry methods
When using the Line editor, you can change the entry method from
"INSERT" (the default) to "OVERWRITE".
After you switch to the overwrite method (by pressing J 4 1),
the triangular cursor will change to a rectangular one, and the number or
function underneath it will be overwritten as you make entries.
Setting the recurring decimal
In NORMAL mode, calculation results can be shown in a recurring
decimal format.
Recurring decimal is OFF: J 5 0 (default)
Recurring decimal is ON:
J 5 1
1
• In the WriteView editor, the recurring part is indicated by "
the Line editor, the recurring part is indicated in parentheses.
• If over 10 digits, including the recurring part, the result cannot be
displayed in recurring decimal format.
Setting of the decimal point
2
You can show the decimal point in the calculation result as either a
dot or a comma.
DOT: J 6 0 (default)
COMMA: J 6 1
• During entry, the decimal point is only shown as a dot.
ENTERING, DISPLAYING, AND EDITING THE EQUATION
The WriteView Editor
Entry and display
In the WriteView editor, you can enter and display fractions or
certain functions as you would write them.
• The WriteView editor can be used in NORMAL mode.
Displaying calculation results (when EXACT is selected)
When possible, calculation results will be displayed using fractions,
p
r, and . When you press U, the display will cycle through the
following display styles:
p
• Mixed fractions (with or without )
p
→
without ) decimal numbers
p
• Proper fractions (with or without
• Irrational numbers (square roots, fractions made using square
→
roots) decimal numbers
Notes:
• In the following cases, calculation results may be displayed using r:
• Arithmetic operations and memory calculations
• Trigonometric calculations
• In trigonometric calculations, when
entering values such as those in
the table to the right, results may be
shown using r.
• Improper/proper fractions will be
converted to and displayed as
decimal numbers if the number of digits used in their expression
is greater than nine. In the case of mixed fractions, the maximum
number of displayable digits (including integers) is eight.
• If the number of digits in the denominator of a fractional result
p
that uses is greater than three, the result is converted to and
displayed as a decimal number.
The Line Editor
Entry and display
In the Line editor, you can enter and display equations line by line.
Notes:
• Up to three lines of text may be viewed on the screen at one time.
• In the Line editor, calculation results are displayed in decimal form
or line fraction notation if possible.
• Use U to switch the display format to fractional form or
decimal form (if possible).
