Basic Operations
TI-30Xa (battery) ¦ ¦ ¦ | turns on theTI-30Xa. } turns off the TI-30Xa and clears display, settings, and pending operations, but not memory. 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: | after APD retrieves display, pending operations, settings, and memory. TI-30Xa Solar ¦ 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 display may contain incorrect numbers. To turn off the TI-30Xa Solar, cover the solar panel with the slide case.
