k Power Requirements and Battery

Replacement

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.
