u Restart

Should the calculator start to act abnormally, you can restart it by pressing the RESTART 
button. Note, however, that you should only use the RESTART button only as a last resort. 
Normally, pressing the RESTART button reboots the calculator’s operating system, so 
programs, graph functions and other data in calculator memory is retained.

The calculator backs up user data (main memory) when you turn power off and loads the 
backed up data when you turn power back on.

 When you press the RESTART button, the calculator restarts and loads backed up data.
This means that if you press the RESTART button after you edit a program, graph function, or 
other data, any data that has not been backed up will be lost.

Pressing the RESTART button to restart the calculator will cause the Battery Settings screen 
to appear on the display. For details about the settings on this screen, see “Battery Settings” 
(page 12-6).
