Auto Shut-Off and Auto Shutdown
The LCD display on your calculator is designed to shut off after 4 minutes
of non-use. If the display powers off, just press the O key to power it
back on. All values are maintained. Your most recent entry will be displayed
and you can scroll through or continue to enter values for the same
calculation you were working on before the display shut off. After 4 hours
of non-use, the calculator will shut down and all temporary settings and
values are cleared.
