Power Supply The type of battery you should use depends on the model number of your calculator. fx-115MS The TWO WAY POWER system actually has two power supplies: a solar cell and a G13 Type (LR44) button battery. Normally, calculators equipped with a solar cell alone can operate only when relatively bright light is present. The TWO WAY POWER system, however, lets you continue to use the calculator as long as there is enough light to read the display. •Replacing the Battery Either of the followi
