Loading Program Library Programs
This calculator comes with a built-in Program Library that provides you with a collection of application programs. Unlike programs you input yourself, you must use the procedure described below to load Program Library programs into memory before you can run them. The Program Library is divided into sub-libraries. You cannot edit or reference the contents of a Program Library program.
To load the program FACT (JAPAN sub-library)
1. On the icon menu, select
2. Use the function keys to execute the LOAD command.

6(g)5(LOAD)

3. Use the and cursor keys and sub-library and then the program.

w to select first the

cc.) JAPAN w (cc.) FACT w
(The message Load Complete! appears for about one second. After that, the display returns to normal.)
You can also jump to a specific location in the sub-library by inputting a letter. Inputting the letter F ( ), for example, causes the highlighting to jump to the first program name in the sub-library that starts with F. The message Memory Full! appears for about one second when there is not enough memory to store the program. Delete data you no longer need and try again.
The screen shown to the right appears when a program with the same name as the one you are trying to load already exists in memory. Perform one of the following key operations when this happens.

YES NO AC

1. Replaces the existing program with the one you are loading. 6. Skips the program with the same name and continues with the load

operation.

A. Aborts the load operation.

4. Press

A to return to the Program List screen.
Now you can run the program using the same procedures that you use to run your own programs.

Important!

Executing some programs change the setting of your calculator. Be sure to check your calculator settings before executing a new program. Access the Web site at the following URL for detailed descriptions of each program does and how to use them: http://world.casio.com/edu_e/

Appendix A Resetting the Calculator
Warning! The procedure described here clears all memory contents. Never perform this operation unless you want to totally clear the memory of the calculator. If you need the data currently stored in memory, be sure to write it down somewhere before performing the RESET operation.

uTo reset the calculator

1. Highlight the MEM icon on the main menu and then press w, or press t.
2. Use c to move the highlighting down to Reset and then press w.
3. Press 1 (YES) to reset the calculator or 6 (NO) to abort the operation without resetting anything.
4. Press m. P.11 If the display appears to dark or dim after you reset the calculator, adjust the contrast.
Resetting the Calculator 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. This should make the RESET screen appear on the display. Perform the procedure to complete the RESET operation.

Appendix A

P button
Pressing the P button while an internal calculation is being performed will cause all data in memory to be deleted.

Appendix B

Power Supply
This calculator is powered by four AAA-size (LR03 (AM4) or R03 (UM-4)) batteries. In addition, it uses a single CR2032 lithium battery as a back up power supply for the memory. If the following message appears on the display, immediately turn off the calculator and replace batteries.
If you try to continue using the calculator, it will automatically turn off in order to protect memory contents. You will not be able to turn power back on until you replace batteries. Be sure to replace the main batteries at least once every two years, no matter how much you use the calculator during that time. The batteries that come with this calculator discharge slightly during shipment and storage. Because of this, they may require replacement sooner than the normal expected battery life. Warning! All memory contents will be deleted if you remove both the main power supply and the memory back up batteries at the same time. If you ever remove both batteries, correctly reload them and then perform the reset operation.

k Replacing Batteries

Precautions: Incorrectly using batteries can cause them to burst or leak, possibly damaging the interior of the calculator. Note the following precautions: Be sure that the positive (+) and negative () poles of each battery are facing in the proper directions. Never mix batteries of different types. Never mix old batteries and new ones. Never leave dead batteries in the battery compartment. Remove the batteries if you do not plan to use the calculator for long periods. Never try to recharge the batteries supplied with the calculator. Do not expose batteries to direct heat, let them become shorted, or try to take them apart.
(Should a battery leak, clean out the battery compartment of the calculator immediately, taking care to avoid letting the battery fluid come into direct contact with your skin.) Keep batteries out of the reach of small children. If swallowed, consult with a physician immediately.
uTo replace the main power supply batteries
* Never remove the main power supply and the memory back up batteries from the calculator at the same time. * Never turn on the calculator while the main power supply batteries are removed or not loaded correctly. Doing so can cause memory data to be deleted and malfunction of the calculator. If mishandling of batteries causes such problems, correctly load batteries and then perform the RESET operation to resume normal operation. * Be sure to replace all four batteries with new ones. 1. Press !O to turn off the calculator. Warning! * Be sure to turn the calculator off before replacing batteries. Replacing batteries with power on will cause data in memory to be deleted. 2. Making sure that you do not accidently press the o key, attach the case to the calculator and then turn it over.
3. Remove the back cover from the calculator by pulling with your finger at the point marked 1. 4. Remove the four old batteries. 5. Load a new set of four batteries, making sure that their positive (+) and negative () ends are facing in the proper directions. 6. Replace the back cover. 7. Turn the calculator front side up and remove its case. Next, press o to turn on power.

BACK UP

Power Supply Power supplied by memory back up battery while the main power supply batteries are removed for replacement retains memory contents. Do not leave the calculator without main power supply batteries loaded for long periods. Doing so can cause deletion of data stored in memory. If the figures on the display appear too light and hard to see after you turn on power, adjust the contrast.

uTo replace the memory back up battery
* Before replacing the memory back up battery, turn on the calculator and check to see if the Low battery! message appears on the display. If it does, replace the main power supply batteries before replacing the back up power supply battery. * Never remove the main power supply and the memory back up batteries from the calculator at the same time. * Be sure to replace the back up power supply battery at least once 2 years, regardless of how much you use the calculator during that time. Failure to do so can cause data in memory to be deleted. 1. Press !O to turn off the calculator. Warning! * Be sure to turn the calculator off before replacing batteries. Replacing batteries with power on will cause data in memory to be deleted. 2. Making sure that you do not accidently press the o key, attach the case to the calculator and then turn it over.
3. Remove the back cover from the calculator by pulling with your finger at the point marked 1. 4. Remove screw i on the back of the calculator, and remove the back up battery compartment cover. 5. Insert a thin, pointed non-metal object (such as a toothpick) into the hole maked j and remove the old battery.
Power Supply 6. Wipe off the surfaces of a new battery with a soft, dry cloth. Load it into the calculator so that its positive (+) side is facing up.
7. Install the memory protection battery cover onto the calculator and secure it in place with the screw. Next, replace the back cover. 8. Turn the calculator front side up and remove its case. Next, press o to turn on power.
k About the Auto Power Off Function
Calculator power turns off automatically if you do not perform any key operation for about 6 minutes. To restore power, press o.

* For a single calculation, calculation error is 1 at the 10th digit. (In the case of exponential display, calculation error is 1 at the last significant digit.) Errors are cumulative in the case of consecutive calculations, which can also cause them to become large. (This is also true of internal consecutive calculations that are performed in the case of ^(xy), x y, x!, 3 x, nPr, nCr, etc.) In the vicinity of a functions singular point and point of inflection, errors are cumulative and may become large.
