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 2 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.

• Keep batteries out of the reach of small children. If swallowed, consult with 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 dipped in 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. 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 burning them.

• When the “Low battery!” message appears on the display, replace the main power supply batteries

as soon as possible.

• 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 P

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.

xix

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.

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.

In no event shall CASIO Computer Co., Ltd. be liable to anyone for special, collateral, incidental, or consequential damages in connection with or arising out of the purchase or use of these materials. Moreover, CASIO Computer Co., Ltd. shall not be liable for any claim of any kind whatsoever against the use of these materials by any other party.

• The contents of this user’s guide are subject to change without notice.

• No part of this user’s guide may be reproduced in any form without the express written consent of the manufacturer.

• The options described in Chapter 22 of this user’s guide may not be available in certain geographic areas. For full details on availability in your area, contact your nearest CASIO dealer or distributor.
