Handling Precautions
Be sure to press the
calculator before using it for the first time.
Even if the calculator is operating normally, replace
the battery at least once every three years. Dead
batteries can leak, causing damage to and malfunction
of the calculator. Never leave the 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 in areas subject 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 become exposed to very high temperature.
Heat can cause discoloration or deformation of the
calculator's case, and damage to internal circuitry.
Avoid use and storage in areas subject 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
elements can damage internal circuitry.
