to turn on the power supply. Press
Ï
n to turn off the power supply.
3 Cursor movement keys: Specifies location to input/correct characters and num-
bers. The cursor is indicated using “_” when there is no number or character. The
cursor is indicated using a flashing “ ” when overlapping a number or character
(this may vary according to setting or display screen). These keys are also used
when selecting menus.
4 Set up key: Mode setting key that determines the calculation method and display
format of this graphing scientific calculator.
5 Clear/Quit key: Used when clearing numerical values, calculation commands,
programs, etc., or when returning to the previous screen. This key is also used when
clearing errors.
6 Alphabet key: Used with Å
to enter letters.
7 Reset switch: Used when replacing batteries or when errors occur. Caution is
required since all memory contents will be deleted when pressing the reset switch.
8 Calculation execution key: Used when specifying calculation commands and
executing calculations.
9 Peripheral connection terminal: Terminal used when connecting separately sold
cables or a PC link cable (not a power supply).
F Secondary function: Used with Ï
to input secondary functions.
G Secondary function specification key: Used when specifying an operation printed
in mustard-yellow above a key (upper left).
H Alphabet specification key: Used when specifying an operation printed in blue
above a key (upper right).

J Graph related keys:
Various settings for graphing can be made using the group of keys indicated in the
box.
•: Used to open the formula input screen for drawing graphs.
•: This function is used for studying graphs and to aid understanding.
(For details, see page 221.)
•: Introduces the user to a mode where expansion and reduction of the
graphing screen, input of main functions and graphing settings can be
performed with ease.
(For details, see CHAPTER 4 “15. Useful Functions” on page 124.)
•: The user can move graph curves and change formats directly with a touch
of a pen (For details, see page 229).
•: Draws a graph using the formula inputted in .
3. Explanation of Keys
• Most keys have more than two functions.
• To use a function printed on a key, simply press the button.
• To specify a function (secondary function) printed in yellow above a key or on the
upper left, press Ï
first.
• To specify a function a character printed in blue on the upper right side of a key,
press the Å key first.
However, there are exceptions to this rule, as in the Menu selection screen, etc.,
where Å does not have to be pressed first.
<Example>
Ï z : Specify sin -1

A : Specify character A
s : Specify sin

5. When Using for the First Time
(1) Inserting batteries
1. Open the battery cover located on
the back of the unit.
To remove the battery cover, pull
down on the tab then lift up.
3. Close the battery cover.
Make sure that the tab that was pulled when
opening the cover is inserted completely and a
snapping sound is heard.
The unit is automatically reset when closing the
battery cover. The display “WAIT” will appear
while the unit initializes settings.
Since the cover also functions as a reset switch,
power will not turn on unless the cover is
attached.
2. Insert batteries as shown in the
diagram to the right.
Be careful to insert the batteries in
the correct direction.
Do not remove the label since it
contains backup battery for
memory protection.

(2) Resetting the calculator
1. Press the RESET switch located on the back of the
unit to clear all data within the calculator’s memory.
• A “WAIT” display will appear momentarily when
pressing the RESET switch. When the display
disappears, the screen shown to the right will appear.
• Press the ¬ key (the display will change to that
shown to the right, indicating that all data within the
internal memory of the calculator has been cleared).
• Move to the standard function calculation screen by
pressing any key.
* The message shown to the right may appear when not
performing the above procedure. To prevent loss of
data, etc., reset the calculator by following the
procedure indicated above.
(3) Adjusting the contrast
Display contrast may vary with the ambient temperature and remaining battery
power. Adjust accordingly for the best view.
Operation:
1. Press Ï q .
The Optional functions menu will appear (see the
diagram on the right).
2. The contrast can be adjusted using + - .
+
: Increases the contrast
-
: Decreases the contrast
3. Press Ï œ to return to the previous screen.

(4) Turning the power off
Press Ï ˙ to turn the power off.
Regarding the automatic power-off function:
The power supply is automatically turned off when there is no operation for a period of
approximately 10 minutes to save battery consumption (the time varies by a few
minutes according to use).
This function will not operate while executing calculations (flashing “ ” on the upper
right side of the screen).
6. Inserting and Removing the Touch-pen
It is possible to store the touch-pen on the side of the main unit when not in use.

7. Caring for Your Calculator
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 vulnerable.
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 environ-
ments.
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 using no solvents.
Do not use a sharp pointed object or exert too much
force when pressing keys.
Avoid excessive physical stress.

This chapter describes the basic key operations (input rules) of the calculator. The
procedures described here show how to perform calculations with common math
functions. This chapter also explains the main set-up functions (mode settings).
1. Entering Numeric Values
The number keys ( 0
to
9 ), and .
and
—
are used to enter numeric
values.
<Example>
To enter “356.25”
Press
¬ 356 .
25.
• To enter an exponent, use
Ï
.
<Example>
To enter “36×1015”
Press
¬ 36 Ï
15.
• To enter a negative (-) number, press — before
entering the number.
* Using -
to enter a negative number generates an error.
-
is used only for subtraction.
