After using function mode. Now I can't switch back to COMP mode.
The shift & mode button is not working.
After waiting for 20 minutes in the table display, I opened the calculator & rested the battery. Now I escaped the table mode. Now returned to which mode, I am unsure.s
Only D & Math is displayed on top of the display.
I can do basic math operations but still can not access the mode or shift button
After auto turning off, the problem remains
