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 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.
Insufficient MEM Error
Cause: 
 An attempt to generate a number table in the 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 “f(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 fulfilled.
Action: Differential or integration calculation: Try increasing the 
tol
 value. 
Note that this also decreases solution precision.
