Action:
• For Attempts, input an integer value that is within the allowable range.
• On the expression registration screen, input a value that is within
the allowable range. In the case of an invalid maximum-minimum
relationship for an entered inequality, edit the inequality to correct the
maximum-minimum relationship.
• On the View-Window screen, input values that are within the
allowable range.
Circular ERROR (f(x) and g(x) feature only)
Cause:
• Circular reference is occurring in a registered composite function
("Registering a Composite Function" (page 54)).
Action:
• Do not have g(x) input into f(x), and f(x) input into g(x) at the same
time.
Not Defined (f(x) and g(x) feature only)
Cause:
• You attempted to calculate f(x) or g(x) with f(x)/g(x) undefined.
Action:
•
Define f(x) or g(x) before calculating f(x)/g(x).
Before Assuming Malfunction of the
Calculator...
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 calculator app for the type of
calculation you are trying to perform.
• To check which calculator app you are currently using, press . This
highlights the icon of the calculator app currently in use.
3. If the above steps do not correct your problem, press the
key.

This causes the calculator to perform a routine that checks whether
calculation functions are operating correctly. If the calculator discovers
any abnormality, it automatically initializes the calculator app and
clears memory contents.
