EL-500M_ENGLISHINTRODUCTIONThank you for purchasing the SHARP Fraction/ScientificCalculator Model EL-500W. This calculator will help youunderstand mathematical concepts behind fraction calcula-tion, such as simplification and reduction.After reading this manual, store it in a convenient locationfor future reference.Operational NotesDo not carry the calculator around in your back pocket, asit may break when you sit down. The display is made ofglass and is particularly fragile.Keep the calculator away from extreme heat such as on acar dashboard or near a heater, and avoid exposing it toexcessively humid or dusty environments.Since this product is not waterproof, do not use it or storeit 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 wetcloth.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 toupgrading without prior notice.SHARP will not be liable nor responsible for any inciden-tal or consequential economic or property damage causedby misuse and/or malfunctions of this product and itsperipherals, unless such liability is acknowledged by law.Press the RESET switch (on the back) only in the follow-ing cases. Note that pressing the RESET switch erasesall data stored in memory.Before using for the first timeAfter replacing the batteriesTo clear all memory contentsIf an abnormal condition occurs and all keys are inop-erative.If service should be required for the calculator, use only aSHARP servicing dealer, SHARP approved service facility,or SHARP repair service where available.Hard CaseDISPLAY(All symbols will not be displayed simultaneously, as shownabove.)

off.
When executing mode selection, last answer memory willbe cleared.Scientific NotationPeople who need to deal with very large and very small num-bers often use a special format called exponential or scientificnotation.A number expressed in scientific notation has two parts. Thefirst part consists of a regular decimal number between 1 and10. The second part represents how large or small the num-ber is in powers of 10.While a calculation result is displayed in the floating pointsystem, press to display the result in the scientific
notation system. Pressing once again will bring
back the floating point system.To enter a number in scientific notation, press E.(1.2 × 10

BATTERY REPLACEMENTNotes on Battery ReplacementImproper handling of batteries can cause electrolyte leakageor 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 inthe calculator.The factory-installed batteries may be exhausted beforethey reach the service life stated in the specifications.When to Replace the BatteriesIf the display has poor contrast or nothing appears on thedisplay even when N is pressed, it is time to replace thebatteries.CautionFluid from a leaking battery accidentally entering an eyecould result in serious injury. Should this occur, wash withclean water and immediately consult a doctor.Should fluid from a leaking battery come into contact withyour skin or clothes, immediately wash with clean water.If the product is not to be used for some time, to avoiddamage to the unit from leaking batteries, remove them andstore in a safe 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.Replacement Procedure
1. Turn the power off by pressing @F.
2. Loosen both screws and remove the bat-tery cover.3. Replace the old batteries with new, withthe positive (+) sides facing up.4. Replace the battery cover and screws.5. Press the RESET switch on the back.Make sure that the display appearsas shown. Otherwise, remove thebatteries, reinstall, and check the dis-play again.Automatic Power Off FunctionThis calculator will turn its power off automatically if no key ispressed for about 10 minutes.SPECIFICATIONSCalculations: General arithmetic operations (add,subtract, multiply, divide, operationswith constants, memory operations,fraction operations, functionoperations, statistical operations,etc.)Internal calculations: Mantissas of up to 12 digitsPending operations: 16 calculations 8 numeric values(4 numeric values in STAT mode)Power source: 3V (DC):Alkaline batteries(LR44 or equivalent) × 2Power consumption: 0.0006 WOperating time: Approx. 2000 hours, whencontinuously displaying 55555. at25°C.
