Sample OperationsSample operations in this manual are indicated by a icon. Unlessspecifically stated, all sample operations assume that the calculator isin its initial default setup. Use the procedure under “3. Initializing theCalculator” to return the calculator to its initial default setup.3. Initializing the CalculatorPerform the following procedure when you want to initialize thecalculator and return the calculation mode and setup to their initialdefault settings. Note that this operation also clears all data currentlyin calculator memory.fx-82MS/85MS/300MS/350MS: p!,(CLR)3(All)=fx-82SX PLUS/220 PLUS: pr3(All)=4. Safety PrecautionsBattery• Keep batteries out of the reach of small children.• Use only the type of battery specified for this calculator in thismanual.5. Handling Precautions• Dim figures on the display of the calculator indicate that batterypower is low. Continued use of the calculator when the batteryis low can result in improper operation. Replace the batteryas soon as possible when display figures becomes dim. Evenif the calculator is operating normally, replace the battery atleast once every two years (fx-82MS/82SX PLUS/220 PLUS), orthree years (fx-85MS/300MS/350MS). A dead battery can leak,causing damage to and malfunction of the calculator. Neverleave a dead battery in the calculator.• The battery that comes with the calculator discharges slightlyduring shipment and storage. Because of this, it may requirereplacement sooner than the normal expected battery life.• Do not use an oxyride battery* or any other type of nickel-basedprimary battery with this product. Incompatibility betweensuch batteries and product specifications can result in shorterbattery life and product malfunction.• Avoid use and storage of the calculator in areas subjectedto temperature extremes, and large amounts of humidity anddust.• Do not subject the calculator to excessive impact, pressure,or bending.RJA521989-001V01 SA0912-A Printed in Chinafx-82MSfx-82SX PLUSfx-85MSfx-220 PLUSfx-300MSfx-350MSUser’s GuideCASIO Worldwide Education Websitehttp://edu.casio.comCASIO EDUCATIONAL FORUMhttp://edu.casio.com/forum/E • Never try to take the calculator apart.• Use a soft, dry cloth to clean the exterior of the calculator.• Whenever discarding the calculator or batteries, be sure todo so in accordance with the laws and regulations in yourparticular area.* Company and product names used in this manual may be registeredtrademarks or trademarks of their respective owners.6.

Turning Power On and OffPress O to turn on the calculator.Press 1A(OFF) to turn off the calculator.Auto Power OffYour calculator will turn off automatically if you do not perform anyoperation for about 10 minutes.8. Adjusting Display Contrast1. Press the , key a number of times untilyou reach the setup screen shown to theright.2. Press c.3. Use d and e to adjust contrast.4. After the setting is the way you want, press A.Important: If adjusting display contrast does not improve displayreadability, it probably means that battery power is low. Replacethe battery.9.

Configuring the Calculator SetupPressing the , key more than once displays additional setupscreens. Underlined ( ___ ) settings are initial defaults.1Deg 2Rad 3Gra Specifies degrees,radians or grads as the angle unit for valueinput and calculation result display.Note: In this manual, the v symbol next to a sample operationindicates degrees.1Fix 2Sci 3Norm Specifies thenumber of digits for display of a calculationresult.Fix: The value you specify (from 0 to 9) controls the number of decimalplaces for displayed calculation results. Calculation results arerounded off to the specified digit before being displayed.Example: 100 ÷ 7 = 14.286 (Fix 3)Sci: The value you specify (from 1 to 10) controls the number ofsignificant digits for displayed calculation results. Calculation resultsare rounded off to the specified digit before being displayed.Example: 1 ÷ 7 = 1.4286 × 10–1(Sci 5)Norm: Selecting one of the two available settings ( Norm 1 , Norm2) determines the range in which results will be displayed in non-exponential format. Outside the specified range, results are displayedusing exponential format.Norm 1: 10–2 | x |, | x | 1010Norm 2: 10–9 | x |, | x | 1010Example: 1 ÷ 200 = 5 × 10–3(Norm 1); 0.005 (Norm 2)bed1ab/c 2 d/c Specifies either mixed fraction (ab/c) or improperfraction (d/c) for display of fractions in calculation results.1Dot 2 Comma Specifies whether to display a dot or acomma for the calculation result decimal point. A dot is alwaysdisplayed during input.Initializing Calculator SettingsPerform the following procedure to initialize the calculator, whichreturns the calculation mode to COMP and returns all other settings,including setup menu settings, to their initial defaults.fx-82MS/85MS/300MS/350MS: p1,(CLR)c(Mode)=fx-82SX PLUS/220 PLUS: prc(Mode)=12.
