Basic Operations
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.
2nd Functions

Results
The calculator can display up to 10 digits plus a minus
sign (-9,999,999,999 through 9,999,999,999) and a
2-digit exponent. Results with more than 10 digits
display in scientific notation.
