l Low battery power can cause memory contents to become corrupted
or lost completely. Always keep written records of all important data.
l Avoid use and storage 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 become exposed to very high temperatures.
Heat can cause discoloration or deformation of the calculator’s case,
and damage to internal circuitry.
l Avoid use and storage 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 elements can damage internal circuitry.
l Never drop the calculator or otherwise subject it to strong impact.
l 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.
l Never try to take the calculator apart.
l Never press the keys on the calculator with a ballpoint pen or
another pointed object.
l Use a soft, dry cloth to clean the exterior of the unit. If the calculator
becomes very dirty, wipe it off with a cloth moistened in a weak
solution of water and a mild neutral household detergent. Wring out
all excess moisture before wiping the calculator. Never use thinner,
benzine or other volatile agents to clean the calculator. Doing so can
remove printed markings and damage the case.
