the specified safety precautions are ignored.
Battery
•
•
•
•
Keep battery out of reach of children. If a battery is
swallowed, seek urgent medical advice.
Do not charge, attempt to disable, short circuit, or apply
heat to the battery.
When installing a new battery, orient it such that the
positive sign is facing upwards.
Use only the battery specified in this manual.

Before using this calculator for the first time, press the % key.
The battery may lose some charge between the time the
calculator leaves the factory and the time when it is purchased.
Thus the original battery may not last as long as a new battery.
When battery power is very low, the calculator’s memory may
become corrupted or be lost completely. To avoid loss of
important information, keep a copy of it elsewhere.
Avoid storing or using the calculator under extreme conditions.
Low temperature will slow the calculator's response time, cause
the display to appear incomplete, and shorten the life of the
battery. In addition, do not directly expose the calculator to the
sun or place near a heater. High temperature may cause the
casing to fade, distort the casing, or damage the internal circuitry.
Avoid storing or using the calculator in damp conditions or when
there is high humidity or excessive dust. Doing so will damage
the internal circuitry.
Do not drop the calculator or allow it to be subjected to extreme
force.
Do not twist, bend or otherwise distort the calculator.
Note: Carrying the calculator in a pocket could cause it to twist or
bend.
Do not use a pen or other pointed object to press the calculator’s
keys.
Use a soft, dry cloth to clean the calculator. Opening the
calculator casing voids the warranty.
If the calculator is very dirty, a neutral household cleanser diluted
in water can be used to clean it. Dip a cloth in the solution and
wring it out before applying it to the calculator. Do not use
benzine, a diluting agent or any other volatile solvent to clean the
calculator. Doing so may damage the casing and the keys.
Before Using the Calculator
Using the Protective Hard Case
1. Before using the calculator, slide the unit out of the protective case as shown in step 1.

Omitting the Multiplication Sign
You can omit the multiplication sign (✕) in any of the following
cases.
•
•
•
Before an open parentheses ():2✕(5 + 4), etc.
Before a general function:
2✕ sin (30), 2✕  (3), etc.
Before a variable name, constant, or random number:
20✕A, 2✕π, etc.
Final Closed Parentheses
You can omit one or more closed parentheses that come at
the end of a calculation immediately before pressing the 
key. For details, see “Omitting a Final Closed Parentheses.”
Displaying a Long Expression
The display can show up to 15 characters at a time. Inputting
the 16th character causes the expression to shift to the left.
The  indicator appears to the left of the expression,
indicating that it runs off the left side of the screen.
Input expression: 1111 + 2222 + 3333 + 444
Displayed Portion:
•
When the  indicator is displayed, you can scroll left and
view the hidden characters by pressing the  key. This
will cause the  indicator to appear to the right of the
expression. Use the  key to scroll back.
Number of Input Characters (Bytes)
•
•
You can input up to 99 bytes of data for a single
expression. Each key operation uses up one byte. A
function that requires two key operations to input (like 
 (sin-1)) also uses only one byte. Note that when you
input functions with Math format, each item you input uses
up more than one byte. For more information, see
“Inputting with Math Format.”
Normally the input cursor appears as a straight vertical ( ❙ )
or horizontal ( _ ) flashing line on the display screen. When
there are 10 or fewer bytes of input remaining in the
current expression, the cursor changes to . If the 
cursor appears, terminate the expression at a convenient
point and calculate the result.

Correcting an Expression
This section explains how to correct an expression as you are
inputting it. The procedure you should use depends on
whether you have insert or overwrite selected as the input
mode.
About Insert and Overwrite Input Modes
In insert mode, the displayed characters shift to the left to
make room when your input replaces the character at the
current cursor position. The initial default input mode is insert.
You can change to overwrite mode as needed.
• The cursor is a vertical flashing line ( ❙ ) when insert mode
is selected. The cursor is a horizontal flashing line ( _ )
when overwrite mode is selected.
• The initial default for Linear format input is insert mode.
You can switch to overwrite mode by pressing  
(INS)
• In Math format, you can only use insert mode. Pressing
  (INS) when Math format is selected does not
switch to overwrite mode. See “Incorporating a Value into
a Function” for more information.
• The calculator automatically changes to insert mode
whenever you change the input/output format from Linear
to Math.

input.
Displaying the Location of an Error
If an error message (like “Math ERROR” or “Syntax ERROR”)
appears when you press , press  or . This displays
the part of the calculation where the error occurred with the
cursor at the error location.
Example: You input “14 ÷ 0 ✕ 2 =” by mistake instead of “14 ÷

Inputting with Math Format
When inputting with Math format, you can input and display
fractions and some functions using the same format as they
appear in your textbook.
IMPORTANT:
• Certain types of expressions can cause the height of a
calculation formula to be greater than one display line. The
maximum allowable height of a calculation formula is two
display screens (31 dots ✕ 2). Further input is not allowed
if the height of the calculation exceeds the limit.
• You can nest functions and parentheses. However, if you
nest too many functions and/or parentheses until input is
no longer permitted, divide the calculation into multiple
parts and calculate each part separately.

Using S-D Transformation
You can use S-D transformation to transform a value between
its decimal (D) form and its standard (S) form (fraction, π).
Formats Supported for S-D Transformation
S-D transformation can be used to transform a displayed
decimal calculation result to one of the forms described below.
Performing S-D transformation again converts back to the
original decimal value.
Note: When you transform from decimal form to standard
form, the calculator automatically decides the standard form
to use. You cannot specify the standard form.
Fraction: The current fraction format setting determines whether the
result is an improper fraction or mixed fraction.
π: The following are the π forms that are supported. This is true
only in the case of Math format. n π (n is an integer).
b
a
--- π or a --- π (depending on fraction format setting).
c

Transformation to a fractional π form is limited to inverse
trigonometric function result and values that are normally
expressed in radians.
After obtaining a calculation result in  form, you can convert
it to decimal form by pressing the  key. When the original
calculation result is in decimal form, it cannot be converted
into  form.

Supported Function Types
•
•
Except for the X variable, other variables (A, B, C, D, Y)
and independent memory (M) are all treated as values
(the current variable assigned to the variable or stored in
independent memory).
Only variable X can be used as the variable of a function.
71
•
•
The coordinate conversion (Pol, Rec) functions cannot be
used for a number table generation function.
Note that the number table generation operation causes
the contents of variable X to be changed.
Start, End, and Step Value Rules
•
•
Linear format is always used for value input.
You can specify either values or calculation expressions (which
must produce a numeric result) for Start, End, and Step.
• Specifying an end value that is less than the Start value
causes an error, so the number table is not generated.
• The specified Start, End, and Step values should produce
a maximum of 30 x-values for the number table being
generated. Executing a number generation table using a
Start, End, and Step value combination that produces
more than 30 x-value causes an error.
Note: Certain functions and Start, End, Step value
combinations can cause number generation to take a long time.
Number Table Screen
The number table screen shows x-values calculated using the
specified Start, End, as well as the values obtained when
each x-value is substituted in the function f(x).
• Note that you can use the number table screen for viewing
values only. Table contents cannot be edited.
• Pressing the  key returns to the function editor screen.
TABLE Mode Precautions
Note that changing the input/output format settings (Math format
or Linear format) on the calculator’s setup screen while in the
TABLE Mode clears the number table generation function.

Precision is basically the same as that described under
“Calculation Range and Precision,” above.
•
^ ( x ) , x y ,  , x!, nPr , nCr type functions require
consecutive internal calculation, which can cause
accumulation of errors that occur with each calculation.
Error is cumulative and tends to be large in the vicinity of a
function’s singular point and inflection point.

Error Messages
The calculator will display an error message when a result
exceeds the calculation range, when you attempt an illegal
input, or whenever any other similar problem occurs.
When an Error Message Appears
The following are general operations you can use when any
error message appears.
•
•
Pressing  or  displays to the calculation expression
editing screen you were using before the error message
appeared, with the cursor located at the position of error.
For more information see “Displaying the Location of an
Error.”
Pressing  clears the calculation expression you were
using before the error message appeared, You can then
re-input and re-execute the calculation, if you want. Note
that in this case, the original calculation will not be retained
in calculation history memory.
Math Error
Cause
•
•
•
The intermediate or final result of the calculation you are
performing exceeds the allowable calculations range.
Your input exceeds the allowable input range (particularly
when using functions).
The calculation you are performing contains an illegal
mathematical operation (such as division by zero).
84
Action
•
•
Check the input values, reduce the number of digits, and
try again.
When using independent memory or a variable as the
argument of a function, make sure that the memory or
variable value is within the allowable range for the
function.
Stack ERROR
Cause
•
The calculation you are performing has caused the
capacity of the numeric stack or the command stack to be
exceeded.
Action
•
•
Simplify the calculation expression so it does not exceed
the capacity of the stack.
Try splitting the calculation into two or more parts.
Syntax ERROR
Cause
•
There is a problem with the format of the calculation you
are performing.
Action
•
Make necessary corrections.
Insufficient MEM Error
Cause
•
There is not enough memory to perform your calculation.
Action
•
Narrow the table calculation range by changing the Start,
End, and Step values, and try again.
Before assuming malfunction of the
calculator
Perform the following steps whenever an error occurs during a
calculation or when calculation are not what you expected. If
one step does not correct the problem, move on to the next
step.
85
Note that you should make separate copies of important data
before performing these steps.
(1) Check that calculation expression to make sure that it
does not contain any errors.
(2) Make sure that you are using the correct mode for the type
of calculation you are trying to perform.
(3) If the above steps do not correct your problem, press the
 key. This will cause the calculator to perform a routine
that checks whether calculation functions are operating
correctly. If the calculator discovers any abnormality, it
automatically initializes the calculation mode and clears
memory contents. For details about initialized settings, see
“Initializing the Calculation Mode and Other Calculator Setup.”
(4) Initialize all modes and settings by performing the
following operations:
  (CLR)  (Setup)  (Yes).
