3/Power Supply

The Two-Way Power System of this calculator uses a solar cell, in addition to one
CR2032 button type battery. Unlike calculators equipped with a solar cell only, you
can use this calculator under virtually any lighting conditions, as long as there is
enough light for you to read the display.
k Battery Replacement
Do not try to replace the battery yourself. Have it replaced by an authorized
CASIO dealer or service center.
If the display becomes dim and difficult to read, or if nothing appears on the display
when you press q (especially when lighting is dim), you probably need to have the
battery replaced.
• A dead battery can leak and damage the calculator if left in the battery compartment
for long periods.
k Auto Power Off Function
This calculator is not equipped with an OFF switch. Instead, it switches power off
automatically about six minutes after the last key operation is performed. To restore
power, press q. Even if the Auto Power Off function operates, the contents of the
independent memory are not cleared.
