H andling Precautions
•Your calculator is made up of precision components. Never try to take it apart.
•Avoid dropping your calculator and subjecting it to other strong impacts.
•Do not store the calculator or leave it in areas exposed to high temperatures
or humidity, or large amounts of dust. When exposed to low temperatures, the
calculator may require more time to display results and may even fail to oper-
ate. Correct operation will resume once the calculator is brought back to normal
temperature.
•The display will go blank and keys will not operate during calculations. When
you are operating the keyboard, be sure to watch the display to make sure that
all your key operations are being performed correctly.
•Replace batteries once every 5 years regardless of how much the calculator is
used during that period. Never leave dead batteries in the battery compartment.
They can leak and damage the unit.
•Avoid using volatile liquids such as thinner or benzine to clean the unit. Wipe
it with a soft, dry cloth, or with a cloth that has been dipped in a solution of water
and a neutral detergent and wrung out.
•In no event will the manufacturer and its suppliers be liable to you or any other
person for any damages, expenses, lost profits, lost savings or any other damages
arising out of loss of data and/or formulas arising out of malfunction, repairs,
or battery replacement. The user should prepare physical records of data to
protect against such data loss.
•Never dispose of batteries, the liquid crystal panel, or other components by burn
ing them.
•Be sure that the power is off when replacing batteries.
•If the calculator is exposed to a strong electrostatic charge, its memory contents
may be damaged or the keys may stop working. In such a case, perform the
Reset operation to clear the memory and restore normal key operation.
•Note that strong vibration or impact during program execution can cause exe
cution to stop or can damage the calculator’s memory contents.
•Before assuming malfunction of the unit, be sure to carefully reread this manual
and ensure that the problem is not due to insufficient battery power, program
ming or operational errors.
