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.
.
The calculation
you are performing has caused the capacity of the matrix or vector 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.
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.
Action:
.
Check .lor errors in the equation that you input.
.
Input a value
for the solution variable that is close to the expected solution and try again.
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.
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.
Note that this also decreases solution precision.

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. Check the calculation expression to make sure that itdoes not contain any
errors.
2. Make sure that you are using the correct mOde for the type of calculation
you are trying to perform.
3.11the 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 the battery will cause all of the calculator's memory
contents to be deleted.
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
minus H ends are facing correctiy.
3. Replace the cover.
4.lnmalize the calculator.
