). Instead, the display shows all

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.
