The Radio Shack EC-453 8-Digit LCD Dual-Powered Calculator is a full-
featured calculator that can operate from two different power sources, so
you can use it almost anywhere.  Your calculator's built-in solar panel
provides power when you expose the calculator to light.  When there is not
enough light to power your calculator through the solar panel, the supplied
internal back-up battery automatically provides power.
