kPower Requirements and BatteryReplacementFC-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.

AReplacing 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.
