If a calculation result satisfies the following conditions, pressing S will
display it as a recurring decimal value.
The total number of digits used in the mixed fraction (including integer,

The data size of value to be displayed as the recurring decimal must be no
larger than 99 bytes. Each value and the decimalpoint require one byte,
and each digij of the periodrequires one byte. The following, for example,
would require oltotal of Bbytes (4 bytesfor the values, 1 byte for the decimal
point, 3 bytes for the period): 0.123

Important: Depending on what you input for the initial value for X (solution
variable), SOLVE may not be able to obtain solutions. If this happens, try
changing the inijial value so they are closer to the solution. SOLVE may not
be able to determine the correct solution, even when one exists. SOLVE
uses Newton's law, so even if there are mulliple solutions, only one of them
wiil be returned. Due to limitations in Newton's law, solutions tend to be
difficult to obtain for equations like the following: y = sin(x), y = c, y = rx.
SOLVE uses Newton's Law to approximate the solution of equations. Note

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

performing.
Action: Make necessary corrections.
Argument ERROR
Cause: There is a problem with the argument of the calculation you are
performing.
Action: Make necessary corrections.

.
Dimension ERROR (MATRIX and VECTOR Modes only)
Cause: The matrix or vector you are trying to use in a calculation was input
without specifying its dimension. You are trying to perform a calculation with
matrices or vectors whose dimensions do not allow that type of calculation.
Action:
Specify the dimension of the matrix or vector and then perform
the calculation again. Check the dimensions specified for the matrices or
vectors to see if they are compatible with the calculation.

.
Variable ERROR (SOLVE feature only)
Cause:
You did not specify a solution variable, and there is no X variable
in the equation you input. The solution variable that you specified is not
included in the equation you input.
Action: The equation you input must include an X variable when you do
not specify the solution variable. Specify a variable that is included in the
equation you input as the solution variable.

.
Can't Solve Error (SOLVE feature only)
Cause: The calculator could not obtain a solution.

Insufficient MEM Enror
Cause: An attempt to generate a number table in th€ TABLE Mode whose
conditions cause it to exceed the maximum number of allowable rows. The
maximum number of rows is 30 when "f(x)" is selected for the setup menu
table setting and 20 when '1(x),g(x)" is selected.
Action: Narrow the table calculation range by changing the Start, End, and
Step values, and try again.

Perform the following steps whenever an error occurs during a calculation
or when calculation results are not what you expected. Ifone step does not
correct the problem, move on to the next step.
Note that you should make separate copies of important data before
performing these steps.
1. errors.
Check the calculation expression to make sure that itdoes not contain any
2. Make sure that you are using the correct mOde for the type of calculation
you are trying to perform.
3.11the above steps do not correct your problem, press the @ID key. This will
cause the calculator to perform a routine that checks whether calculation
functions are operating correctly. Ifthe calculator discovers any abnormality,
itautomatically initializes the calculation mode and clears memory contents.
For details about initialized settings. see 'Configuring the Calculator
Setup".
4. Initialize all mOdes and settings by performing the following operation:
I!!1IIID(CLR) (I)(Setup)@(Yes).
Re~Cin!Lthe Batt~ry
__
A low battery is indicated by a dim display, even if contrast is adjusted, or by
failure of figures to appear on the display immediately after you tum on the
calculator. If this happens, replace the battery with a new one.
Important:
Removing
contents to be
deleted. the battery will cause all of the calculator's memory
1.Press 1!!11@(OFF) to tum off the calculator.
" To ensure that you do not accidentally tum on power while replacing the
battery, slide the hard case onto the front of the calculator.
2. Remove the cover as shown in the illustration and
Screw
replace the battery, taking care that its plus (+) and

Time Out Error
Cause: The current differential or integration calculation ends without the
ending condition being fulfilled. The current distribution calculation ends
without the ending condition being fullilled.
Action: Differential or integration calculation: Try increasing the tol value.

.Frequently
Asked Questions
_ ___-==
. How can I perform inpu1 and display results the same way I did on a
model that does not have Natural Textbook Display?
Perform the following key operation: IIDI!!iiI(SETUP)IIJ(lineIO).
See
"Configuring the Calculator Setup" on page E-5 for more information.
. How can I change a fraction form result to decimal form?
How can I change a fraction form result produced by a division
operation to decimal form?
See "Toggling Calculation Results" on page E-14 for the procedure.
. What Is the difference between Ans memory, PreAns memory,
Independent memory, and variable memory?
Eachofthese types of memory acts like "containers"for temporary storage
of a single value.
Ans Memory: Stores the result of the last calculation performed. Use this
memory to carry the result of one calculation on to the next.
PreAns Memory: Stores the result of calculation before the last one.
PreAns memory can be used only in the COMP Mode.
Independent Memory: Use this memory to totalize the results of multiple
calculations.
Variables: This memory is helpful when you need to uses the same value
multiple times in one or more calculations.
. Whatis the keyoperationto take me from the STAT Mode or TABLE
Modeto a mode where I can perform arithmetic calculations?
Press I!i!!II) (COMP).
. HowcanIreturnthecalculator

Perform the fQllowing operation; I!!iJ(IJ(ClR)II)(Setup)@(Yes)
. WhenI execu1ea function calculation, why do I get a calculation result
that Is completely different from older CASIO calculator models?
Witha NaturalTextbook Display model, the argument of a function that
uses parentheses must be followed by a closing parenthesis. Failing to
press
alter the argumentto closethe parenthesesmay cause unwanted
values or expressions to be included as part of the argument.
