Question about Casio ClassPad 300 Calculator
Check the batteries. At the bottom right of the screen, above the H-Copy and ESC pictograms there is a battery gauge that shows you how much energy is left (approximately).
Regardless of what the guage shows, you might want to change the batteries.
Check the power saving mode. If the Auto power Off is set to a short time span (1min) the calculator will turn off after 1 minute of inactivity.
