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
ѿ(1҂10

kPower Supply
•fx-82SOLAR/fx-260SOLAR
This calculator is powered by a solar cell that converts avail-
able light into electrical power.
Solar Cell Precautions
•The 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.
