To ensure trouble-free operation, please observe the following
points:
1. Do not carry the calculator in the back pocket of slacks or
trousers.
2. Do not subject the calculator to extreme temperatures.
3. Do not drop it or apply excessive force.
4. Clean only with a soft, dry cloth.

[Data Correction]
Correction prior to pressing k:
Physical constants can be recalled in the normal mode (when not
set to binary, octal, or hexadecimal), 3-VLE mode, or statistics
mode.
Delete incorrect data with ª.
Differential/Integral Functions
(5)
Correction after pressing k:
Differential and integral calculations are only available in the nor-
mal mode. For calculation conditions such as the x value in differ-
ential calculation or the initial point in integral calculation, only
numerical values can be entered and equations such as 22 cannot
be specified. It is possible to reuse the same equation over and
over again and to recalculate by only changing the conditions
without re-entering the equation.
The inputted statistical data can be traced back by pressing
[. Display the data to correct, press @J to delete,
then input the correct value.
Note: Physical constants and metric conversions are based either
on the 1986 values released by the Committee on Data for
Science and Technology (CODATA) of ICSU (International
Council of Scientific Unions) or on ISO specifications.

In this calculator, all calculation results are internally obtained in
scientific notation with up to 12 digits for the mantissa. However,
since calculation results are displayed in the form designated by
the display notation and the number of decimal places indicated,
the internal calculation result may differ from that shown in the
display. By using the modify function, the internal value is con-
verted to match that of the display, so that the displayed value can
be used without change in subsequent operations.

Performing Calculations
[When performing integral calculations]
Integral calculations, depending on the
integrands and subintervals included, require
longer calculation time. During calculation,
“Calculating!” will be displayed. To cancel cal-
culation, press ª. In addition, please note
that there will be greater integral errors when
there are large fluctuations in the integral val-
ues during minute shifting of the integral range
and for periodic functions, etc., where positive
and negative integral values exist depending
on the interval.
For the former case, divide integral intervals
as small as possible. For the latter case,
separate the positive and negative values.
Following these tips will allow results of cal-
culations with greater accuracy and will also
shorten the calculation time.
An error will occur if an operation exceeds the calculation ranges,
or if a mathematically illegal operation is attempted. When an error
occurs, pressing < (or >) automatically moves the cursor
back to the place in the equation where the error occurred. Edit the
equation or press ª to clear the equation.
