Welcome to the world of graphing calculators.

Quick-Start is not a complete tutorial, but it takes you through many of the most common

functions, from turning the power on, to specifying colors, and on to graphing complex

equations. When you’re done, you’ll have mastered the basic operation of this calculator and

will be ready to proceed with the rest of this user’s guide to learn the entire spectrum of

functions available.

Each step of the examples in Quick-Start is shown graphically to help you follow along

quickly and easily. When you need to enter the number 57, for example, we’ve indicated it

as follows:

Press

Whenever necessary, we’ve included samples of what your screen should look like.

If you find that your screen doesn’t match the sample, you can restart from the beginning

by pressing the “All Clear” button

TURNING POWER ON AND OFF

To turn power on, press o.

To turn power off, press !

OFF

Note that the calculator automatically turns power off if you do not perform any operation

for about six minutes (about 60 minutes when a calculation is stopped by an output

command (^)).

USING MODES

This calculator makes it easy to perform a wide range of calculations by simply selecting

the appropriate mode. Before getting into actual calculations and operation examples, let’s

take a look at how to navigate around the modes.

To s el ect the RUN Mode

1. Press m to display the Main Menu.

* The above shows the CFX-9850

(9950)G(B) PLUS screen.

Quick-Start

2. Use defc to highlight RUN and then

press w.

This is the initial screen of the RUN mode, where you

can perform manual calculations, and run programs.

BASIC CALCULATIONS

With manual calculations, you input formulas from left to right, just as they are written on

paper. With formulas that include mixed arithmetic operators and parentheses, the calcula-

tor automatically applies true algebraic logic to calculate the result.

Example:

15 × 3 + 61

1. Press o to clear the calculator.

2. Pressbf*d+gbw.

Parentheses Calculations

Example:

15 × (3 + 61)

1. Press

again. As you do, a box appears on the display. Move

the pointer so the box encloses the area you want to

enlarge.

4. Press

w, and the enlarged area appears in the

inactive (right side) screen.

DYNAMIC GRAPH

Dynamic Graph lets you see how the shape of a graph is affected as the value assigned

to one of the coefficients of its function changes.

Example:

To learn all about the many powerful features of this calculator, read on and explore!

•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.

Handling Precautions

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 calcula-

tions, 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.
