In the case of condition e, you could also press k. This clears the intermediate result just prior to the overflow, so you can continue with the calculation from that point.

No error occurs when the result is within the range of (11099)to (11099). Instead, the display shows all zeros.

kPower Supply

fx-82SOLAR/fx-260SOLAR

This calculator is powered by a solar cell that converts available light into electrical power.

Solar Cell PrecautionsThe solar cell requires at least 50 lux of light to provide power.

If available light is too low, the display may become dim, calculation functions may become impossible, or the con- tents of the independent memory may be lost. If this happens, move to an area with more light.

fx-85B/fx-280

This calculator is powered by the CASIO TWO- WAY POWER system, which makes it possible for the calculator to operate even in total darkness.

The calculator retains memory contents no matter what the lighting conditions.

The TWO-WAY POWER system uses two power sources: a solar cell and a single G13 Type (SR44 or LR44) battery.

Weak battery power is indicated when memory contents spontaneously clear, or when the display darkens under poor light and cannot be restored by pressing 5.
