FC-200V
Your calculator uses a TWO WAY POWER system that
combines a solar cell with button battery LR44 ҂ 1.
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.
A Replacing the Battery
The battery needs to be replaced after a specific number
of years. Also, replace the battery immediately after display
figures become dim.
A low battery is indicated by a dim display, even if contrast
is adjusted, or by failure of figures to appear on the display
immediately after you turn on the calculator. If this happens,
replace the battery with a new one.
Important!
• Removing the battery will cause all of the calculator’s
memory contents to be deleted.
1. Press 1A(OFF) to turn off
the calculator.
2. On the back of the calculator,
remove the screws and the
cover.
3. Remove the battery, and then
load a new battery with its plus
(+) and minus (–) ends facing
correctly.
4. Replace the cover.
