APD™ (Automatic Power Down™) turns off the
TI-30Xa automatically if no key is pressed for about
5 minutes, but does not clear display, settings,
pending operations, or memory.
Note:

To turn on the TI-30Xa Solar, expose the solar
panel to light and press . Note: Always press
to clear the calculator because memory and
