INTRODUCTION
Thank you for purchasing the SHARP Scientific Calculator Model
EL-509W/531W/531WG/531WH.
About the calculation examples (including some formulas and
tables), refer to the reverse side of this English manual. Refer to
the number on the right of each title on the manual for use.
After reading this manual, store it in a convenient location for
future reference.
Note: Some of the models described in this manual may not be
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 exces-
sively 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.
• 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 up-
grading without prior 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 batteries
• To clear all memory contents
• When an abnormal condition occurs and all keys are inop-
erative.
If service should be required on this calculator, use only a SHARP
servicing dealer, SHARP approved service facility, or SHARP
repair service where available.

BEFORE USING THE CALCULATOR
Key Notation Used in this Manual
In this manual, key operations are described as follows:
@e
To specify e x :
I
To specify ln :
Kü
To specify F :
Functions that are printed in orange above the key require @ to
be pressed first before the key. When you specify the memory,
press K first. Numbers for input value are not shown as keys,
but as ordinary numbers.
Power On and Off
Press ª to turn the calculator on, and @F to turn it off.
Clearing the Entry and Memories
Clearing methods are described in the table as follows:

[About the Memory clear key]
Press @∏ to display the menu.
• To clear all variables (M, A-F, X, Y, ANS, STAT VAR), press
00 or 0®.
• To RESET the calculator, press 10 or 1®.
The RESET operation will erase all data stored in memory, and
restore the calculator's default setting.
Entering and Correcting the Equation
[Cursor keys]
• Press < or > to move the cursor. You can also return to
the equation after getting an answer by pressing > (<).
See the next section for using the [ and ] keys.
• In the SET UP menu and other locations, use the < or >
key to move the flashing cursor, then press ® (= key).
If you need to scroll up/down the view, use the [ or ]
key.
[Insert mode and Overwrite mode in the Equation display]
• This calculator has two editing modes: insert mode (default), and
overwrite mode. Pressing @' switches between the two
modes. A triangular cursor indicates that an entry will be inserted
at the cursor, while the rectangular cursor indicates to overwrite
preexisting data as you make entries.
• To insert a number in the insert mode, move the cursor to the
place immediately after where you wish to insert, then make a
desired entry. In the overwrite mode, data under the cursor will
be overwritten by the number you enter.
• This mode setting will be retained until the next RESET operation
is executed.
