2.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.

•Your calculator supports use of both alkaline batteries and rechargeable nickel-metal hydride batteries. Note that the amount of operation between charges provided by nickel-metal hydride batteries is shorter than the life of alkaline batteries. Use only batteries that are specifically recommended for this calculator.

•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. Immediately remove nickel-metal hydride batteries from the calculator after their charge is used up. Leaving uncharged nickel-metal hydride batteries in the calculator can cause them to deteriorate.

•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.

•Avoid contact with water and other liquids.

Though your calculator is designed to be splash-resistant, note that splash-resistance is reduced if it is exposed to moisture, dirt, or dust while the battery compartment cover, USB port cap, SD card cap, or other opening is uncovered. Moisture getting into the calculator creates the risk of malfunction, fire, and electric shock.

1-3

•Do not swing the calculator around by its strap. Doing so creates the risk of calculator malfunction and personal injury.

•Avoid opening the battery compartment cover, USB port cap, and SD card cap in areas where moisture or salt wind is present, when your hands are wet, when wearing wet gloves, etc.

•Periodically check the battery compartment cover, USB port cap, SD card cap, and the areas around them for dirt, sand, and other foreign matter. If any of these areas are dirty, use a soft, clean, and dry cloth to wipe them. Note that even a minute particle of foreign matter (a single strand of hair, a single grain of sand, etc.) on a cover or cap contact surface creates the risk of moisture reaching the calculator interior.

•If the calculator is exposed to large amounts of rain or other water, wipe it dry. Make sure that all moisture is removed before using the calculator again.

•Do not use the calculator for long periods in the rain.

•When closing the battery compartment cover, USB port cap, or SD card cap, inspect its gasket for cracks, damage, looseness, or other irregularities, and make sure that the cover or cap closes securely.

•Take care to avoid dropping the calculator and do not leave it in an area that is outside the allowable operating temperature range. Such conditions can cause deterioration of splash and/or dust resistance.

•Calculator accessories and options are not splash or dust resistant.

•Subjecting the calculator to extreme shock may cause loss of splash and/or dust resistance.

•CASIO COMPUTER CO., LTD. shall held in no way liable for any malfunction of or damage to the calculator or SD card being used, or for any corruption or deletion of memory contents due to problems related to invasion of moisture that may occur due to misuse by you.

•CASIO COMPUTER CO., LTD. shall not be held responsible for any problems caused by exposure of this calculator to moisture.

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

Busy indicator

Progress bar

Never press the RESTART 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.

1-4

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.

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.

4.Splash Resistance, Dust Resistance, and Shock Resistance

kSplash Resistance and Dust Resistance

This calculator satisfies the requirements of the IP54* splash proof and dust proof protection levels defined by the International Electrotechnical Commission (IEC).

*IP stands for “ingress protection”. The “5” of the left digit means Class 5 (no ingress of dust that affect device operation) protection against solid objects. The “4” means Class 4 protection against liquids (no harmful effects from water sprayed from all directions).

kShock Resistance

This calculator has cleared independent testing by CASIO that was conducted based on the United States Defense Department MIL-STD-810G shock resistance performance test methods*. Test methods are those described below.

Local testing by natural dropping of the calculator to the floor (P tile on concrete) from a height of 122 cm on six faces. Test data represents actual cumulative values based on CASIO standards, and do not constitute any guarantee of non-destruction of or nondamage to the actual product exterior.

*Environmental laboratory test method (Method 516.6-Shock) of the United States Department of Defense MIL-STD-810G military standard, which requires passage by a total of at least five devices, which are drop tested from a height of 122 centimeters (4 feet) onto a plywood (lauan) drop zone, in groups of five, for a total of 26 drops (6 faces, 8 corners, 12 edges)

Important!

•Shock resistance testing assumes exposure to shock during normal everyday use. Subjecting the calculator to extreme shock may destroy it.

•Even if exposure to shock does not result in calculator operational performance, it can cause scratching of the calculator’s display or other damage.

•Splash resistance, dust resistance, and shock resistance testing of this calculator was performed using CASIO test methods. No guarantees are made concerning the ability of the calculator to be impervious to damage and/or malfunction.

Now enter the correct mode and perform your calculation again, monitoring the results on the display.

kRestart and Reset

uRestart

Should the calculator start to act abnormally, you can restart it by pressing the RESTART button. Note, however, that you should only use the RESTART button only as a last resort. Normally, pressing the RESTART button reboots the calculator’s operating system, so programs and other data in calculator memory is retained.

RESTART button

2-16

Important!

The calculator backs up user data (main memory) when you turn power off and loads the backed up data when you turn power back on.

When you press the RESTART button, the calculator restarts and loads backed up data. This means that if you press the RESTART button after you edit a program or other data, any data that has not been backed up will be lost.

uReset

Use reset when you want to delete all data currently in calculator memory and return all mode settings to their initial defaults.

Before performing the reset operation, first make a written copy of all important data. For details, see “Reset” (page 9-3).

kLow Battery Message

If the following message appears on the display, immediately turn off the calculator and replace batteries as instructed.

If you continue using the calculator without replacing batteries, power will automatically turn off to protect memory contents. Once this happens, you will not be able to turn power back on, and there is the danger that memory contents will be corrupted or lost entirely.

•You will not be able to perform data communications operations after the low battery message appears.
