INTRODUCTION
Thank you for purchasing the SHARP Scientific Calculator Model EL-509WM/
509WS.
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.
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.
• 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.
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 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.
