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
a
is the same for a
b
,
◊
, n!, e
, ln, etc., where continuous calculations are performed internally).
b
x
•
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.
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)
cause syntax error.

When a numerator or a denominator is negative, the calculation will cause error.

•
Percentage display: Fixed decimal (2 digits decimal)
•
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.
•
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.
