notation. The display mode can be changed according tothe purpose
of the calculation.

displays the result again in theloating point system.
Pressing@iand any value between 0 and 9 speci-ies the number of
decimal places in the calculation result.
To clear the setting of decimal places, press@i..
SCIENTIFIC CALCULATIONS
Calculate in the normal mode. In each example, pressto clear the
display.
Arithmetic Operations The closing parenthesis)just
before=or;
may be omitted. When entering only a decimal place, it is not
necessary to
press0before..
Random NumbersA pseudo-random number with three significant
digits can begenerated by pressing@`. Random number gen-eration is
not possible when binary/octal/hexadecimal sys-tem mode is set.
Angular Unit ConversionsEach time@gare pressed, the angular unit
changesin sequence.
Memory CalculationsThis calculator has one independent memory
(M). It is avail-able in the normal mode and binary, octal,
hexadecimalsystem mode.
The independent memory is indicated by the three
keys:O,R,;.Before starting a calculation, clear the memory by
press-ingandO.
A value can be added to or subtracted from an existingmemory
value. When subtracting a number from thememory, pressand;.
The contents of the memory are retained even when thecalculator
is turned off. A value stored in memory will thusremain until it is
changed or until the batteries run out.
Chain CalculationsThis calculator allows the previous
calculation result to be
used in the following calculation.The previous calculation
result will not be recalled after en-tering multiple
instructions.
Time, Decimal and Sexagesimal CalculationsThis calculator
performs decimal-to-sexagesimal conversionand
sexagesimal-to-decimal conversion. In addition, the fourbasic
arithmetic operations and memory calculations can becarried out
using the sexagesimal system.Notation for sexagesimal is as
follows:
123.404080degree second
minute
Note: When the calculation or conversion result is con-verted, a
residual may occur.
Constant Calculations In the constant calculations, the addend
becomes a con-
stant. Subtraction and division are performed in the samemanner.
For multiplication, the multiplicand becomes aconstant.
Functions Refer to the calculation examples of each function.
For most calculations using functions, enter numerical
values before pressing the function key.

STATISTICAL CALCULATIONS
Press@to select statistics mode.The following statistics can be
obtained:
x Mean of samples (xdata)
sx Sample standard deviation (xdata)
x Population standard deviation (xdata)
n Number of samples
x Sum of samples (xdata)
x2 Sum of squares of samples (xdata)
Data Entry and CorrectionEntered data are kept in memory
until@orFare pressed. Before entering new data, clear the
memorycontents.

samedata)
[Data Correction]Correction prior to pressingk:
Delete incorrect data with.Correction after pressingk:Reenter
the data to be corrected and press@J. The number displayed after
pressingkor@J
during data entry or correction is the number of samples(n).
Statistical Calculation FormulasIn the statistical calculation
formulas, an error will occur when: the absolute value of the
intermediate result or calculation
result is equal to or greater than 1 10100. the denominator is
zero. an attempt is made to take the square root of a negative
number.
INARY, OCTAL, DECIMAL, AND
EXADECIMAL OPERATIONS (N-BASE)is calculator can perform the four
basic arithmetic opera-ns, calculations with parentheses and memory
calcula-ns using binary, octal, decimal, and hexadecimal num-rs.hen
performing calculations in each system, first set thelculator in
the desired mode before entering numbers.can also perform
conversions between numbers expressedbinary, octal, decimal and
hexadecimal systems.
onversion to each system is performed by the followingys:
: Converts to the binary system. BINappears.
: Converts to the octal system. OCTappears.
: Converts to the hexadecimal system. HEXappears.
: Converts to the decimal system. BIN, OCT,
and HEXdisappear from the display.
onversion is performed on the displayed value when theseys are
pressed.
ote: In this calculator, the hexadecimal numbers A F are
entered by pressingE,,,,I,
andl, and displayed as follows:A , B , C , D , E , F
the binary, octal, and hexadecimal systems, fractionalrts cannot
be entered. When a decimal number having actional part is converted
into a binary, octal, or hexadeci-
al number, the fractional part will be truncated. Likewise,hen
the result of a binary, octal, or hexadecimal calculationcludes a
fractional part, the fractional part will be trun-ted. In the
binary, octal, and hexadecimal systems, nega-e numbers are
displayed as a complement.

COMPLEX NUMBER CALCULATIONS
carry out addition, subtraction, multiplication, and divisioning
complex numbers, press@to select the com-
ex number mode.A complex number is represented in the a + bi
format. Thea is the real part while the bi is the imaginary
part.When inputting the real part, after inputting the
numberpressa. When inputting the imaginary part, after in-putting
the number pressb. To obtain the result press=.Immediately after
completing calculation, you can recall
the value of the real part witha, and the value of theimaginary
part withb.If the complex numbers are represented as polar
coordi-nates, press@} after they are input withaandb.
ERROR AND CALCULATION RANGES
ErrorsAn error will occur if an operation exceeds the
calculationranges, or if a mathematically illegal operation is
attempted.In the case of an error, the display will show E.An error
can be cleared by pressing.
Calculation Ranges Within the ranges specified, this calculator
is accurate to
1 of the least significant digit of the mantissa. However,
acalculation error increases in continuous calculations dueto
accumulation of each calculation error. (This is thesame for yx, x,
ex, ln, etc., where continuous calculationsare performed
internally.)Additionally, a calculation error will accumulate
andbecome larger in the vicinity of inflection points andsingular
points of functions.
Calculation ranges10-99~ 9.9999999991099and 0.
If the absolute value of an entry or a final or
intermediateresult of a calculation is less than 1099, the value is
consid-ered to be 0 in calculations and in the display.

ATTERY REPLACEMENT
tes on Battery Replacementproper handling of batteries can cause
electrolyte leakageexplosion. Be sure to observe the following
handling rules:Replace both batteries at the same time.Do not mix
new and old batteries.Make sure the new batteries are the correct
type.When installing, orient each battery properly as indicated
inhe calculator.Batteries are factory-installed before shipment,
and may be
exhausted before they reach the service life stated in
thespecifications.
hen to Replace the Batterieshe display has poor contrast, the
batteries require replace-nt.
utionFluid from a leaking battery accidentally entering an eye
couldesult in serious injury. Should this occur, wash with
clean
water and immediately consult a doctor.Should fluid from a
leaking battery come in contact with yourskin or clothes,
immediately wash with clean water.f the product is not to be used
for some time, to avoid damage
o the unit from leaking batteries, remove them and store in
asafe place.Do not leave exhausted batteries inside the product.Do
not fit partially used batteries, and be sure not to mixbatteries
of different types.Keep batteries out of the reach of
children.Exhausted batteries left in the calculator may leak
anddamage the calculator.Explosion risk may be caused by incorrect
handling.Do not throw batteries into a fire as they may
explode.
placement ProcedureTurn the power off by pressingF.Loosen both
screws and remove the battery cover. (Fig. 1)
Fig. 1 Fig. 2
Remove the used batteries then replace with two freshbatteries

cover and screws.Press.Make sure that the display appears as shown
below. If the
display does not appear as shown, reinstall the batteriesand
check the display once again.
tomatic Power Off Functions calculator will turn itself off to
save battery power if no
y is pressed for approximately 8 minutes.
