ERRORS

There are several situations which will cause an overflow or an error condition. When

this occurs, “E” will be displayed. The contents of the memory at the time of the error are

retained.

If “0 • E” is displayed at the time of the error, “– – – – – – –” will be printed in red and C CE

must be used to clear the calculator.

Error conditions:

1.When the integer portion of an answer exceeds 12 digits.

2.When the integer portion of the contents of the memory exceeds 12 digits. (Ex. M 999999999999 M+ 1 M+ )

3.When any number is divided by zero. (Ex. 5 0 ).
