The calculator will display an error message whenever an error occurs for
any reason during a calculation. There are two ways to exit an error message
display: Pressing d or e to display the location of the error, or pressing
A to clear the message and calculation.
Displaying the Location of an Error
While an error message is displayed, press d or e 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.
When you input 14 ÷ 0 × 2 = by mistake instead of 14 ÷ 10 × 2 =
Clearing the Error Message
While an error message is displayed, press A to return to the calculation
screen. Note that this also clears the calculation that contained the 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 (particularly when using functions). • The calculation you are
performing contains an illegal mathematical operation (such as division
