Technical Information
Errors
The calculator will display an error message whenever an error occurs for any reason during a calculation.
Press 
or 
to return to the calculation screen. The cursor will be positioned at the location where the error occurred, ready for input. Make the necessary corrections to the calculation and execute it again.
Press 
to return to the calculation screen. Note that this also clears the calculation that contained the error.
Error Messages
Math ERROR
Cause:
The intermediate or final result of the calculation you are performing exceeds the allowable calculation range.
Your input exceeds the allowable input range.
The calculation you are performing contains an illegal mathematical operation (such as division by zero).
Action:
Check the input values and reduce the number of digits.
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.
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.
Arg ERROR
Cause:
Improper use of an argument.
Action:
Make necessary corrections.
Dim ERROR (MAT and VCT 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.
Can't solve Error (SOLVE feature only)
Cause:
The calculator could not obtain a solution.
Action:
Check for errors in the equation that you input.
Input a value for the solution variable that is close to the expected solution and try again.
