Handling Precautions

  Be sure to press the O   key before using the

calculator for the first time.

  Even if the calculator is operating normally, replace

the battery at least once every three years (FC 200V)

or two years (FC 100V).

A dead battery can leak, causing damage to and

malfunction of the calculator. Never leave a dead battery

in the calculator.

  The battery that comes with this unit discharges

slightly during shipment and storage. Because of

this, it may require replacement sooner than the

normal expected battery life.

  Low battery power can cause memory contents to

become corrupted or lost completely. Always keep

written records of all important data.

  Avoid use and storage of the calculator in areas

subjected to temperature extremes.

Very low temperatures can cause slow display response,

total failure of the display, and shortening of battery life.

Also avoid leaving the calculator in direct sunlight, near

a window, near a heater or anywhere else it might be

exposed to very high temperatures. Heat can cause

discoloration or deformation of the calculator's case, and

damage to internal circuitry.

  Avoid use and storage of the calculator in areas

subjected to large amounts of humidity and dust.

Take care never to leave the calculator where it might be

splashed by water or exposed to large amounts of

humidity or dust. Such conditions can damage internal

circuitry.

  Never drop the calculator or otherwise subject it to

strong impact.

  Never twist or bend the calculator.

Avoid carrying the calculator in the pocket of your trousers

or other tight fitting clothing where it might be subjected

to twisting or bending.

  Never try to take the calculator apart.
