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.
• 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 All 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 manual and ensure that the
problem is not due to insufficient battery power, programming or operational errors.
xvii
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.

k About the Display Screen
This calculator uses two types of display: a text display and a graphic display. The
text display can show 21 columns and eight lines of characters, with the bottom line
used for the function key menu, while the graph display uses an area that measures
127 (W) × 63 (H) dots.

k About Menu Item Types
This calculator uses certain conventions to indicate the type of result you can expect
when you press a function key.
• Next Menu
Example:
Selecting
displays a menu of hyperbolic functions.
• Command Input
Example:
Selecting
inputs the sinh command.
• Direct Command Execution
Example:

k Exponential Display
The calculator normally displays values up to 10 digits long. Values that exceed this
limit are automatically converted to and displayed in exponential format. You can
specify one of two different ranges for automatic changeover to exponential display.
Norm 1 ........... 10–2 (0.01) > |x|, |x| > 1010
Norm 2 ........... 10–9 (0.000000001) > |x|, |x| > 1010
uTo change the exponential display range
1. Press !Z to display the Set Up Screen.
2. Use f and c to move the highlighting to “Display”.
3. Press 3 (Norm).
The exponential display range switches between Norm 1 and Norm 2 each time you
perform the above operation. There is no display indicator to show you which expo-
nential display range is currently in effect, but you can always check it by seeing
what results the following calculation produces.
Ab/caaw
(Norm 1)
(Norm 2)
All of the examples in this manual show calculation results using Norm 1.
uHow to interpret exponential format
1.2E+12 indicates that the result is equivalent to 1.2 × 1012. This means that you
should move the decimal point in 1.2 twelve places to the right, because the expo-
nent is positive. This results in the value 1,200,000,000,000.
1.2E–03 indicates that the result is equivalent to 1.2 × 10–3. This means that you
should move the decimal point in 1.2 three places to the left, because the exponent
is negative. This results in the value 0.0012.

k Special Display Formats
This calculator uses special display formats to indicate fractions, hexadecimal val-
ues, and sexagesimal values.

..... Indicates: 12° 34’ 56.78"
• In addition to the above, this calculator also uses other indicators or symbols,
which are described in each applicable section of this manual as they come up.
k Calculation Execution Screen
Whenever the calculator is busy drawing a graph or executing a long, complex cal-
culation or program, a black box (k) flashes in the upper right corner of the display.
This black box tells you that the calculator is performing an internal operation.
