Handling Precautions
•Your calculator is made up of precision components. Never try to take it apart.
•Avoid dropping your calculator and subjecting it to strong impact.
•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 operate. 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.

•Never dispose of batteries, the liquid crystal panel, or other components by burning them.
•Be sure that the power switch is set to OFF when replacing batteries.

•If the calculator stops operating correctly for some reason, use a thin, pointed object to press the RESTART button on the back of the calculator. Note, however, that this clears all the data in calculator memory.
•Note that strong vibration or impact during program execution can cause execution to stop or can damage the calculator’s memory contents.
