What does the “E” on my display mean?

The “E” stands for “Error”. This problem can usually be resolved by resetting your calculator. Visit our Product Manuals page and locate your model number. Click on Product Manuals or Quick Start Guide for instructions on how to reset your calculator.

The “Error” can also be caused by Memory Overload. If you are using the Grand Total or Sigma function, be sure to periodically clear Grand Total and Sigma by pressing GT or Sigma Total twice.
