FC-200V
Your calculator uses a TWO WAY POWER system that
combines a solar cell with G13 type button battery (LR44).
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
Dim display figures when available lighting is dim or failure
of anything to appear on the display immediately when
you turn on the calculator indicates that button battery
power is low. Note that you will not be able to use the
calculator if its button battery is dead. When any of these
symptoms occur, replace the button battery.
Even if the calculator is operating normally, replace the
battery at least once every three years.
Important!
• Removing the button battery from the calculator causes
independent memory contents and values assigned to
variables to be cleared.
1. Press 1A(OFF) to turn off
the calculator.
• To ensure that you do not
accidentally turn on power
while replacing the battery,
slide the hard case onto the
front of the calculator.
2. On the back of the calculator,
remove the screw and the
battery cover.
3. Remove the old battery.
