BATTERY REPLACEMENT
Notes on Battery Replacement
Improper handling of batteries can cause electrolyte leakage
or explosion. 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 correctly as indicated in
the calculator.
• The factory-installed batteries may be exhausted before
they reach the service life stated in the specifications.
When to Replace the Batteries
If the display has poor contrast or nothing appears on the
display even when N is pressed, it is time to replace the
batteries.
Cautions
• 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
batteries of different types.
• Keep batteries out of the reach of children.
• Exhausted batteries left in the calculator may leak and
damage the calculator.
• Explosion risk may be caused by incorrect handling.
• Do not throw batteries into a fire as they may explode.

Chain Calculations
• This calculator allows the previous calculation result to be
used in the following calculation.
• The previous calculation result will not be recalled after
entering multiple instructions.
• In the case of utilizing postfix functions (¿ , sin, etc.), you
can perform a chain calculation even when the previous
calculation result is cleared by the use of the N or @
c keys.
Calculating the Highest Common Factor
(H.C.F.) or Lowest Common Multiple (L.C.M.)
To calculate the H.C.F. or the L.C.M., the procedures are as
follows:
What is the H.C.F. N 24 24_
of 24 and 36? @‹ 36 24HCF36_
= 12.
What is the L.C.M. N 15 15_
of 15 and 9? @ˆ 9 15LCM9_
= 45.
• “Highest Common Factor” is synonymous with “Greatest
Common Factor”, “Lowest Common Multiple” is with “Least
Common Multiple”.
Calculating quotient and remainder
“: Calculates the quotient and remainder.
• Pressing “ cannot be followed by pressing a key for
another operation such as (+, –, Ч, ч), otherwise an error
will result.
• The calculator can display a quotient or remainder up to 5
digits in length, including the “–” sign. If numbers longer
than 5 digits are entered, normal division is performed.
23 ÷ 5 N 23 @“ 5 23‘5_
(R: Remainder) = 4. R 3.
9.5 ÷ 4 9.5 @“ 4 9.5‘4_
= 2. R 1.5
–32 ÷ (–5) – 32 @“– 5 –32‘–5_
= 6. R –2.
FRACTION CALCULATIONS
Entering Fractions
• To enter fractions, use the following keys:
Ø : Places the symbol “ /” between the numerator
and the denominator.
∞ : Separates the integer (whole number) part from
the fractional part of a mixed number.
Calculating with Fractions
Fractions can be incorporated into an arithmetic calculation.
The “SIMP” symbol will appear with a calculation result if the
answer can be further simplified. Refer to the following sec-
tion of this manual for details.
* If = is pressed instead of a number entry, the lowest
common denominator will automatically be displayed.

Calculation Ranges
• Within the ranges specified below, this calculator is
accurate to ±1 of the least significant digit of the
mantissa. However, a calculation error increases in con-
tinuous calculations due to accumulation of each cal-
culation error. (This is the same for y
x , x ¿ ¿ ¿ ¿ ¿ y , etc. where
continuous calculations are performed internally.)
Additionally, a calculation error will accumulate and
become larger in the vicinity of inflection points and
singular points of functions.
• Calculation range: ±10 -99 ~ ±9.999999999 ×10 99 and 0.
If the absolute value of an entry or a final or intermediate
result of a calculation is less than 10
–99 , the value is consid-
ered to be 0 in calculations and in the display.

Error Codes and Error Types
Syntax error (Error 1):
•
An attempt was made to perform an invalid operation.
Ex. 2 +- 5 =
Calculation error (Error 2):
•
The absolute value of an intermediate or final calculation result
equals or exceeds 10

• An attempt was made to divide by 0.
• The calculation ranges were exceeded while performing calcu-
lations.
Depth error (Error 3):

buffers* for numeric values and 16 buffers for calculation in-
structions).
* 4 buffers in STAT mode.
Equation too long (Error 4):
•

[Automatic Simplification]
* If you do not know a common factor, press =. The
greatest common factor “6” will be displayed.
[Manual Simplification]
* “2” is entered as a factor, and “SIMP” will be displayed
to indicate further simplification of the fraction is possible.
If the entered value is not a common factor, the cursor will
be set under the value. Press d to clear the value, then
enter a correct common factor. Press N to return to the
“FACTOR?” display.

How to Simplify a Fraction
Reducing to its simplest form
If the result of pressing = is displayed with the “SIMP”
symbol, the calculation can be reduced further. Use the ª
key to set the factor of the fraction to simplify, either automati-
cally or manually.
Memory Calculations
This calculator has two memory allocations: independent
memory (M), and last answer memory (ANS). You will find
them especially useful when combinations of calculations be-
come complicated, or when applying the answer of previous
calculation to another operations.
• Press NO to clear the independent memory (“M”
symbol will disappear).
• After pressing R to recall a value stored in the memory,
the value as displayed will be used in the calculation.
Independent memory (M)
O : Stores the result in the memory.
R : Recalls the value stored in the memory.
@; : Adds the result to the value in the memory.
Last answer memory (ANS)
When = is pressed, the calculation result will automati-
cally be stored in the last answer memory.
@? : Recalls the value stored in the last answer
memory.

If the entered value is not a common denominator, the
cursor will be set under the value. Press d to clear the
value, then enter a correct common denominator. Press
N to return to the “DENOM.?” display.
Now that you have learned how to reduce a fraction to its

ERROR AND CALCULATION RANGES
Errors
An error will occur if an operation exceeds the calculation
ranges, or if a mathematically illegal operation is attempted. If
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 N to clear the
equation.

INTRODUCTION
Thank you for purchasing the SHARP Scientific Calculator
Model EL-530V. This calculator will help you understand math-
ematical concepts behind fraction calculation, such as simpli-
fication and reduction.
After reading this manual, store it in a convenient location for
future reference.
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. Rain-
drops, water spray, juice, coffee, steam, perspiration, etc.
will also cause malfunction.
• Clean with a soft, dry cloth. Do not use solvents or wet
cloth.
• Do not drop it or apply excessive force.
• Never dispose of batteries in a fire.
• Keep batteries out of the reach of children.
• This product, including accessories, may change due to
upgrading without prior notice.
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 periph-
erals, 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 batteries
• To clear all memory contents
• If an abnormal condition occurs and all keys are
inoperative.
If service should be required on this calculator, use only a
SHARP servicing dealer, SHARP approved service facility, or
SHARP repair service where available.
Hard Case
• All symbols will not be displayed simultaneously, as shown
above.
• Certain inactive symbols may appear visible when viewed
from a far off angle.

played. Press </> to see the remaining (hid-
den) section.
2ndF : Appears when @ is pressed, indicating that the
functions shown in orange are enabled.
