Calculator not responding
If the calculator does not respond, you should rst try to reset it. This is much like restarting a PC. It cancels
certain operations, restores certain conditions, and clears temporary memory locations. However, it does not
clear stored data (variables, apps, programs, etc.).
To reset
Turn the calculator over and insert a paper clip into the Reset hole just above the battery compartment cover.
The calculator will reboot and return to Home view.
