available in some countries.
Operational Notes
• Do not carry the calculator around in your back pocket, as it may
break when you sit down. The display is made of glass and is
particularly fragile.
• Keep the calculator away from extreme heat such as on a car
dashboard or near a heater, and avoid exposing it to excessively
humid or dusty environments.
• Since this product is not waterproof, do not use it or store it where
fluids, for example water, can splash onto it. Raindrops, water spray,
juice, coffee, steam, perspiration, etc. will also cause malfunction.
• Clean with a soft, dry cloth. Do not use solvents or a wet cloth. Avoid
using a rough cloth or anything else that may cause scratches.
• Do not drop it or apply excessive force.
• Never dispose of batteries in a fire.
• Keep batteries out of the reach of children.
• For the sake of your health, try not to use this product for long
periods of time. If you need to use the product for an extended
period, be sure to allow your eyes, hands, arms, and body adequate
rest periods (about 10–15 minutes every hour).
If you experience any pain or fatigue while using this product,
discontinue use immediately. If the discomfort continues, please
consult a doctor.
• This product, including accessories, may change due to upgrading
without prior notice.
NOTICE
• SHARP strongly recommends that separate permanent written
records be kept of all important data. Data may be lost or
altered in virtually any electronic memory product under certain
circumstances. Therefore, SHARP assumes no responsibility for
data lost or otherwise rendered unusable whether as a result of
improper use, repairs, defects, battery replacement, use after the
specified battery life has expired, or any other cause.
• SHARP will not be liable nor responsible for any incidental or
consequential economic or property damage caused by misuse
and/or malfunctions of this product and its peripherals, unless
such liability is acknowledged by law.
♦ Press the RESET switch (on the back), with the tip of a ball-point
pen or similar object, only in the following cases. Do not use an
object with a breakable or sharp tip. Note that pressing the RESET
switch erases all data stored in memory.
• When using for the first time
• After replacing the battery
• To clear all memory contents
• When an abnormal condition occurs and all keys are inoperative
♦ If service should be required on this calculator, have the calculator
serviced in the region (country) where you purchased it.

integral values 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 you to obtain results from calculations
with greater accuracy and will also shorten the calculation time.

Chain Calculations
The previous calculation result can be used in the subsequent
calculation. However, it cannot be recalled after entering multiple
instructions or when the calculation result is in matrix/vector format.
Fraction Calculations
Arithmetic operations and memory calculations can be performed using
fractions. In NORMAL mode, conversion between a decimal number and
a fraction can be performed by pressing U.
Notes:
• Improper/proper fractions will be converted to and displayed as decimal
numbers if the number of digits used in their expression is greater
than nine. In the case of mixed fractions, the maximum number of
displayable digits (including integers) is eight.
• To convert a sexagesimal value to a fraction, first convert it by pressing
@ :.

Binary, Pental, Octal, Decimal, and Hexadecimal
Operations (N-base)
Conversions can be performed between N-base numbers in NORMAL
mode. The four basic arithmetic operations, calculations with
parentheses, and memory calculations can also be performed, along with
the logical operations AND, OR, NOT, NEG, XOR, and XNOR on binary,
pental, octal, and hexadecimal numbers.
Note: The hexadecimal numbers A–F are entered by pressing m
B C D E
, A , l , i , and H
*
In the binary, pental, octal, and hexadecimal systems, fractional parts
cannot be entered. When a decimal number having a fractional part
is converted into a binary, pental, octal, or hexadecimal number, the
fractional part will be truncated. Likewise, when the result of a binary,
pental, octal, or hexadecimal calculation includes a fractional part,
the fractional part will be truncated. In the binary, pental, octal, and
hexadecimal systems, negative numbers are displayed as a complement.
Time, Decimal, and Sexagesimal Calculations
You can convert between decimal and sexagesimal numbers, and from
sexagesimal numbers to seconds or minutes. In addition, the four basic
arithmetic operations and memory calculations can be performed using
the sexagesimal system. Notation for sexagesimal is as follows:
Degree
Minute

pressed, the number of decimal places (TAB) can be set to any value
between 0 and 9.
• When @ J 1 1 (SCI) is pressed, the number of
significant digits can be set to any value between 0 and 9. Entering 0
will set a 10-digit display.

numbers if the number of digits used in
their expression is greater than nine. In the case of mixed fractions, the
maximum number of displayable digits (including integers) is eight.
• If the number of digits in the denominator of a fractional result that uses
p

Modify Function
Decimal calculation results are internally obtained in scientific notation,
19
with up to 14 digits in 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 (@ n),
the internal value is converted to match that of the display, so that the
displayed value can be used without change in subsequent operations.
• When using the WriteView editor, if the calculation result is displayed
using fractions or irrational numbers, press U to convert it to
decimal form first.
• The modify function can be used in NORMAL, STAT, MATRIX, or
VECTOR modes.

• A positive integer greater than 2 and no more than 10 digits can be
factored into primes.
• A number that cannot be factored into a prime number with 3 digits
or shorter is shown in parentheses.
• The calculation result of prime factorization is displayed according to
the editor setting (W-VIEW or LINE).
• The calculation result of prime factorization may extend off the
edges of the screen. You can see those parts by pressing l or
r. To jump to the left end or right end, press @ l or @
