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.

(Manually specify 6, the Great-

est Common Factor of 12 and 6, to simplify the fraction.)
Do not leave exhausted batteries inside the product.
Do not fit partially used batteries, and be sure not to mix different batteries types.

Notes: • If the wrong number is specified for a common factor,
an error will occur.
•
• Calculation may take considerable amount of time if
the factor is set to a large digit integer (6-digit or more, for example).
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.)
[
2→a b/c] Converts an improper fraction to a mixed number.
The calculation error increases in continuous calculations due to accumulation of each calculation error (that

a
is the same for ab,◊b, n!, ex, ln, etc., where continuous calculations are performed internally).
<Example>
Calculation errors will accumulate and become larger into the vicinity of inflection points and singular points
of functions. (For example, calculation of sinh x or tanh x at 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.

COMMUNICATION PORT
Data can be displayed in two modes:
•
Value display: 7 digits
•
Communication port*
Percentage display: Fixed decimal (2 digits decimal)
•
Communication between EL-9450 and EL-9400 is not possible.
Use CE-LK1P and PC to transfer the data from the EL9400.
Pie graphs are drawn in the same order as on the specifying list.
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.

NEW FEATURES
The values are stored in variables A to H.

•
As all the displayed values are rounded off in the percentage display mode, the total percentage may not be 100.
