Precautions when Using this Product

A progress bar and/or a busy indicator appear on the display whenever the calculator is performing a calculation, writing to memory (including Flash memory), or reading from memory (including Flash memory).

Busy indicator

Progress bar

Never press the P button or remove the batteries from the calculator when the progress bar or busy indicator is on the display. Doing so can cause memory contents to be lost and can cause malfunction of the calculator.

This calculator is equipped with Flash memory for data storage. It is recommended that you always backup your data to Flash memory. For details about the backup procedure, see “12-7 MEMORY Mode” in the User’s Guide.

You can also transfer data to a computer using the Program-Link software (FA-124) that comes bundled with the calculator. The Program-Link software can also be used to backup data to a computer.

u fx-9860G SD only

If the message “No Card” appears even though an SD card is loaded in the SD card slot, it means that the calculator is not recognizing the card for some reason. Try removing the card and then loading it again. If this does not work, contact the developer of the SD card. Note that some SD cards may not be compatible with this calculator.

Precautions when Connecting to a Computer

A special USB driver must be installed on your computer in order to connect to the calculator. The driver is installed along with the Program-Link software (FA-124) that comes bundled with the calculator. Be sure to install the Program-Link software (FA-124) on your computer before trying to connect the calculator. Attempting to connect the calculator to a computer that does not have the Program-Link software installed can cause malfunction. For information about how to install the Program-Link software, see the User’s Guide on the bundled CD-ROM.

20050401

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.

•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 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.

•Battery life can be reduced dramatically by certain operations and by the use of certain types of

SD cards.

20050401

Be sure to keep physical records of all important data!

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.

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.
