Before Assuming Malfunction Of The Calculator - Casio fx-500ES User Manual

• 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).
• 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.
k Before assuming malfunction of the calculator...
Perform the following steps whenever an error occurs during a calculation or when
calculation results are not what you expected. If one 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 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 O 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 Settings" under "Calculation Modes and Calculator Setup".
(4) Initialize all modes and settings by performing the following operation:
19(CLR) 1(Setup) =(Yes).
