Precautions for handling batteries
•Fluid from a leaking battery accidentally entering an eye could result in serious injury. Should this occur, wash
with clean water and immediately consult a doctor.
•Should fluid from a leaking battery come into contact with your skin or clothes, immediately wash with clean
water.
•If the product is not to be used for some time, to avoid damage to the unit from leaking batteries, remove them
and store in a safe place.
•Do not leave exhausted batteries inside the product.
•Do not fit partially used batteries, and be sure not to mix different batteries types.
Note of calculation accuracy
•In principle, the calculation error is ±1 of the last digit (in case of exponential display, the calculation error is
±1 of the last digit of the mantissa display.)
•The calculation error increases in continuous calculations due to accumulation of each calculation error (that
is the same for ab, a ◊b, n!,
e
x, ln, etc., where continuous calculations are performed internally).
•Calculation errors will accumulate and become larger into the vicinity of inflection points and singular points
of functions. (For example, calculation of sinh xor tanh xat x= 0).
INTRODUCTION
Congratulations on purchasing the EL-9450 Graphing Calculator. The basic functions of the EL-9450 are the
same as the EL-9400. See the enclosed EL-9400 operation manual for almost all the operations. This supple-
ment describes about the features added from the EL-9400, such as fraction calculations (Manual Calculations),
pie chart (Statistics), and int÷/remain functions (Manual Calculations). It also describes the feature updates, such
as capability of a self-made Slide Show, random function, commands for programming. Read both the EL-9400
Operation Manual (where EL-9400 and CE-LK1 should be read as EL-9450 and CE-LK1P respectively) and this
supplement before operation.
Please store both the manual and the supplement in a convenient location for your reference.

Integer part of the mixed number must be a natural number. A variable cannot be
used. Using parenthesis in an equation, such as (1+2) 2 3 or (5) 2 3, will
cause syntax error.
*
When a numerator or a denominator is negative, the calculation will cause error.
Automatic/Manual Simplification
In the mixed or fraction calculation, you can select the automatic (default) or manual simplification of
a fraction.
To set to the manual simplification:

•Pie graphs cannot be displayed simultaneously with other graphs and X/Y
axis, though lines or dots can be drawn. The coordinates of the free-moving
cursor depend on the Window settings.
•The values are stored in variables A to H.

1. Creating an Original Slide Show
The calculator provides a function which allows you to create your own slide show screens and
register them.
•The number of screens which you can store may vary depending on the amount of free memory. (It is
possible to register as many screens as the memory capacity allows. However, if you use up most of the
memory for the slide show, this may affect other calculations.)
•A title can be put on the original slide show. (Only one title can be put on the slide show.)
•The flowchart for creating your original slide show is shown below.
Enter the slide show creation mode. :
C ®
Put a title on the slide show. : Input a title. ®
Register screens. : After creating an original slide show, press Ï to store
the original slide show.
•The original slide show has no specific end mark. (When another slide show is created following the
original slide show, the previous data is cleared and updated by the new slide show.)
<Example>
Input “Y1 = 2X–5” and “Y2 = X2”, and then store the equations, graph screen, table screen, and
graph and table screen in sequential order. (Set to the X-Y coordinate system.)
1. Press
¬ .
2. Press
C ® .
Selects the original slide show (new slide show) creation mode.
3. lnput the title as “GRAPH”. (Up to 8 characters can be used for
the title.)
