• To cancel an incorrect entry, press the opposite operation key. This

Error and Overflow Conditions and Indicators
If you divide by zero or calculate a selling price using a margin of 100%, an
error occurs. The calculator prints ERROR
An overflow occurs if you calculate a result with too many digits for the
calculator to display or print. When this occurs, the calculator:
• Displays E and the first 12 digits of the result with a decimal point 11
places to the left of its correct position.
• Prints ERROR and the first 12 digits of the result with the decimal
shifted 11 places to the left of its correct position.
To clear an error or overflow,
unless the error or overflow occurred in a memory calculation.
