Caring for Your Calculator
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 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.
• Do not use a sharp pointed object or exert too much force when
pressing keys.
•Avoid excessive physical stress.

Getting Started
Before Use
Inserting
batteries resetting the
memory
1. Open the battery cover
located on the back of the
calculator. Pull down the
notch, then lift the battery
cover up to remove it.
2. Insert the batteries, as
indicated. Make sure that
the batteries are inserted in
the correct directions.
Do not remove the label
since it contains backup
battery for memory protection.
3. Place the battery cover back, and make sure that the notch is
snapped on.
The unit will automatically start its own initialization sequence.
After a moment of “WAIT” message displayed on the screen,
the following message will appear:
PRESS [CL] TO CLEAR ALL DATA
PRESS [ON] KEY TO CANCEL
Note: If the above message does not appear, check the direction of the
batteries and close the cover again. If this does not solve the
problem, follow the instruction described in "Resetting the
Calculator - 1. Using the RESET switch" on page 25.
4. Press C to reset the calculator’s memory. The memory will
be initialized. Press any key to set the calculator ready for
normal calculation mode.

Quick Run-through: Fraction Calculation
Here are the major ingredients for 18 doughnuts:
1
cup warm water
4
3
cup warm milk
4
1
cup sugar
3
4 cups all-purpose flour
2 eggs
3 tablespoons butter
Based on these values, solve the following problems using the calculator.
Question If you make 60 doughnuts according to the above recipe,
how many cups of warm milk are required?
At first, you may calculate how many cups of warm milk are
required for 1 doughnut =
3
÷ 18

As for the ordinary calculation, the answer is 0.041666666. But
how much is 0.041666666 of a cup of warm milk?
The answer has three modes, Decimal numbers, Mixed (numbers) and Improp(er numbers). If the Mixed or Improp answer
mode is selected in the SETUP menu, you can obtain the answer
in fractions.

Use the number keys (0 ~ 9), decimal point key (.), and negative
number key (_) to enter numbers into the calculator. To clear the screen entry,
press C.

enter a value in scientific notation.
Example
6.3

Entering a
negative value
The negative number key _ can be used to enter numbers,
lists, and functions with negative values. Press _ before
entering the value.
Note: Do not use the - key to specify a negative value. Doing so
will result in an error.
Example
Type
-9460.827513 into the Calculation
screen.
# C _ 9460.827513
2. Performing standard math calculations
By utilizing the + - | and = keys, you can perform the standard
arithmetic calculations of addition, subtraction, multiplication, and division. Press
E to perform each calculation.

Example
Obtain the answer to “6

Chapter 2: Operating the Graphing Calculator
Using
parentheses
With the ( and ) keys, parentheses (round brackets)
can be added to group sections of expressions. Sections within
the parentheses will be calculated first. Parentheses can also be
used to close the passings of values in various functions, such as
“round(1.2459,2)”.
Example
Obtain the answer to “(9
+ 7) × (5 – 3)”.
# C ( 9 + 7 )
| ( 5 - 3 ) E
Note: The multiplication sign “×”, as the one
in the above example, can be abbreviated if it proceeds a math function, a parenthesis “(”, or a variable.
Abbreviating “(1
+ 2) × 3” to “(1 + 2) 3” will result in an error.
Cursor Basics
The cursor indicates where the next entry will be placed. The cursor may be placed
automatically to different areas by various functions and tools, or can be moved
around by using the ; ' { } keys. Use the cursor keys to select a
menu item, select an item in a list, and trace along a graph.
Example

The root figure is entered, with the cursor automatically placed
below the figure.
For detailed instructions of how to use the @ key, refer to
“Second Function Key” and “ALPHA Key” in this chapter.

Use @ to call up the calculator’s extended key functions, math functions and
figures.
All functions associated with @ are color coded yellow, and are printed above
each key.
Example
Enter “2π” on the screen.
1. Press # C to clear the screen, then enter “2” by
pressing 2.

$ Input π (3.14...) figure.
z Input a variable (X for rectangular or T for parametric)
i Gives an answer as a quotient and a remainder
d Enters a mixed number.
Note: If a number precedes d b a and _, then the
number will be set as the first entry of the figure. Else, the first
entry is blank and the cursor flashes.

MATH, STAT, and PRGM Menu Keys
By using the M, S, and P keys, you can access many menu items for
complex calculation tasks. The appendix “List of Menu/Sub-menu Items” shows the
contents of each sub-menu item.
Example
Round the following number beyond the decimal point: 34.567
1. Press # C, then M. The
MATH menu takes over the screen,
as shown to the right. MATH menu
items are displayed on the left side
of the screen.
2. Use the { and } keys to move the cursor up and
down the menu. As you scroll, you will see the corresponding
sub-menu contents (shown on the right side of the screen)
change.
3. Set the cursor at B NUM.
Menu items can also be selected by using shortcut keys (A
through H); in this example, simply press B to select B
NUM. There is no need to use A for this operation.
4. Press a shortcut key 2 to
select 2 round(. The screen now
goes back to the calculation screen,
as follows:
Another way of selecting the submenu item is to press ' (or
E) on the menu item B NUM. The cursor will be extended
into the sub-menu on the right. Now, move the cursor on the
sub-menu down to 2 round(, then press E.
5. Type 3 4 . 5 6 7 , 0
), and press E.

DRG: For trigonometric calculations and coordinate conversions,
various angle units can be selected:
Deg Angle values to be set in degrees
Rad Angle values to be set in radians (default)
Grad Angle values to be set in grads
FSE: Var ious decimal formats can be set:
FloatPt Answers are given in decimal form with a floating
decimal point (default).
Fix Answers are given in decimal form. The decimal point
can be set in the TAB menu.
Sci Answers are given in “scientific” notation. For example,
“3500” is displayed as “3.500000000E3”. The decimal
point can be set in the TAB menu.
22
Eng Answers are given in “engineering” notation with
exponents set to be multiples of 3. “100000” will be
displayed as “100.0000000E3”, and “1000000” will be
shown as “1.000000000E6”. The decimal point can be
set in the TAB menu.
Note: If the value of the mantissa does not fit within the range
±0.000000001 to ±9999999999, the display changes to
scientific notation. The display mode can be changed
according to the purpose of the calculation.
TAB: Sets the number of digits beyond the decimal point (0 through 9).
The default is “9”.
COORD: Sets the calculator to the rectangular or parametric graph
coordinate system.
Rect Rectangular coordinates (default)
Param Parametric equation coordinates
Chapter 2: Operating the Graphing Calculator
ANSWER: Sets the answer preference to various number formats.
Decimal Answers will be given in decimal form (default)
Mixed Answers will be given in mixed fractions, whenever
appropriate
Improp Answers will be given in improper fractions, whenever
appropriate
EDITOR: Sets the editing style to one of two available formats.
Eqn Formulas can be entered in
a “display as written”
approach (default setting).
Oneline Formulas will be displayed
on one line.
Notes: Immediately after changing the EDITOR, the calculator will return
to the calculation screen and the following data will be cleared.
• ENTRY memory
• Equations stored in the graph equation window (Y)
* Resetting to the default settings (@ p E 1)
will also clear the above data.
Expression of up to 114 bytes can be entered in the Equation
edit mode. If the expression exceed the screen width, it is
horizontally extended.
Expression of up to 160 bytes can be entered in one-line edit
mode. If the expression exceed the screen width, it goes to the
next line.
