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.  
• Replace the main batteries once every one year 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.  
• Do not use an oxyride battery* or any other type of nickel-based primary battery with this product.  
Incompatibility between such batteries and product specifications can result in shorter battery life  
and product malfunction.  
• Keep batteries out of the reach of small children. If swallowed, consult a physician immediately.  
• 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 moistened with a solution of water and a neutral detergent and  
wrung out.  
• Always be gentle when wiping dust off the display to avoid scratching it.  
• 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. It is up to you to  
prepare physical records of data to protect against such data loss.  
• 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 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.  
• 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.  
• Using the calculator near a television or radio can cause interference with TV or radio reception.  
• Before assuming malfunction of the unit, be sure to carefully reread this User’s Guide and ensure  
that the problem is not due to insufficient battery power, programming or operational errors.  
* Company and product names used in this manual may be registered trademarks or trademarks of  
their respective owners.  
E-2  
Be sure to keep physical records of all important data!  
The large memory capacity of the unit makes it possible to store large amounts of data.  
You should note, however, that low battery power or incorrect replacement of the batteries that  
power the unit can cause the data stored in memory to be corrupted or even lost entirely. Stored  
data can also be affected by strong electrostatic charge or strong impact. It is up to you to keep  
back up copies of data to protect against its loss.  
Since this calculator employs unused memory as a work area when performing its internal  
calculations, an error may occur when there is not enough memory available to perform  
calculations. To avoid such problems, it is a good idea to leave 1 or 2 kbytes of memory free  
(unused) at all times.
