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.
