    Be sure to keep all user documentation handy for future reference.
    2. Sample Operations
    Sample operations in this manual are indicated by a icon. Unless
    specifically stated, all sample operations assume that the calculator is
    in its initial default setup. Use the procedure under “3. Initializing the
    Calculator” to return the calculator to its initial default setup.
    3. Initializing the Calculator
    Perform the following procedure when you want to initialize the
    calculator and return the calculation mode and setup to their initial
    default settings. Note that this operation also clears all data currently
    in calculator memory.

    4. Safety Precautions
    Battery
    • Keep batteries out of the reach of small children.
    Use only the type of battery specified for this calculator in this
    manual.
    5. Handling Precautions
    Dim figures on the display of the calculator indicate that battery
    power is low. Continued use of the calculator when the battery
    is low can result in improper operation. Replace the battery
    as soon as possible when display figures becomes dim. Even
    if the calculator is operating normally, replace the battery at
    least once every two years (fx-82MS/82SX PLUS/220 PLUS), or
    three years (fx-85MS/300MS/350MS). A dead battery can leak,
    causing damage to and malfunction of the calculator. Never
    leave a dead battery in the calculator.
    The battery that comes with the calculator discharges slightly
    during shipment and storage. Because of this, it may require
    replacement sooner than the normal expected battery life.
    Do not use an oxyride battery* or any other type of nickel-based
    primary battery with this product. Incompatibility between
    such batteries and product specifications can result in shorter
    battery life and product malfunction.
    Avoid use and storage of the calculator in areas subjected
    to temperature extremes, and large amounts of humidity and
    dust.
    Do not subject the calculator to excessive impact, pressure,
    or bending.

    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 to
    do so in accordance with the laws and regulations in your
    particular area.

    6. Removing the Hard Case
    Before using the calculator, slide
    its hard case downwards to
    remove it, and then affix the hard
    case to the back of the calculator
    as shown in the illustration
    nearby.
    7. Turning Power On and Off
    Press O to turn on the calculator.
    Press 1A(OFF) to turn off the calculator.
    Auto Power Off
    Your calculator will turn off automatically if you do not perform any
    operation for about 10 minutes.
    8. Adjusting Display Contrast
    1. Press the , key a number of times until
    you reach the setup screen shown to the
    right.
    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 display
    readability, it probably means that battery power is low. Replace
    the battery.
    9. Reading the Display
    The display of the calculator shows expressions you input, calculation
    results, and various indicators.

    Standard deviation
    N2(SD)
    Regression calculations (fx-82MS/85MS/
    300MS/350MS only)
    N3(REG)
    Note: • The initial default calculation mode is the COMP Mode.
    • Mode indicators appear in the upper part of the display. Be sure to
    check the current calculation mode (COMP, SD, REG) and angle unit
    setting (Deg, Rad, Gra) before beginning a calculation.
    11. Configuring the Calculator Setup
    Pressing the , key more than once displays additional setup
    screens. Underlined ( ___ ) settings are initial defaults.
    1Deg 2Rad 3Gra Specifies degrees,
    radians or grads as the angle unit for value
    input and calculation result display.
    Note: In this manual, the v symbol next to a sample operation
    indicates degrees.
    1Fix 2Sci 3Norm Specifies the
    number of digits for display of a calculation
    result.
    Fix: The value you specify (from 0 to 9) controls the number of decimal
    places for displayed calculation results. Calculation results are
    rounded 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 of
    significant digits for displayed calculation results. Calculation results
    are 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 , Norm
    2) determines the range in which results will be displayed in non-
    exponential format. Outside the specified range, results are displayed
    using exponential format.

    comma for the calculation result decimal point. A dot is always
    displayed during input.
    Initializing Calculator Settings
    Perform the following procedure to initialize the calculator, which
    returns the calculation mode to COMP and returns all other settings,
    including setup menu settings, to their initial defaults.

    4 × sin30 × (30 + 10 × 3) = 120 v
    4 *s 30 *( 30 + 10 * 3 )=
    Note: • The memory area used for calculation input can hold 79
    “steps”. One step is taken up each time you press a number key
    or arithmetic operator key ( +, -, *, /). A ! or a (fx-
    82MS/85MS/300MS/350MS only) key operation does not take up a
    step, so inputting !W(
    3
    '), for example, takes up only one step.
    • Whenever you input the 73rd step of any calculation, the cursor
    changes from “_” to “ k” to let you know memory is running low.
    Calculation Priority Sequence
    When the priority of two expressions is the same, the calculation is
    performed from left to right.

    Calculation History (Not included on the fx-82SX PLUS)
    In the COMP Mode, the calculator remembers up to approximately
    150 bytes of data for the newest calculation. You can scroll through
    calculation history contents using f and c.
    1 + 1 = 2 1 + 1 = 2.
    2 + 2 = 4 2 + 2 = 4.
    3 + 3 = 6 3 + 3 = 6.
    (Scrolls back.) f 4.
    (Scrolls back again.) f 2.
    Note: Calculation history data is all cleared whenever you press O,
    when you change to a different calculation mode, or whenever you
    initialize modes and settings.
    Replay (Not included on the fx-82SX PLUS)
    While a calculation result is on the display, you can press d or e
    to edit the expression you used for the previous calculation.
    4 × 3 + 2.5 = 14.5 4 * 3 + 2.5 = 14.5
    4 × 3 − 7.1 = 4.9
    (Continuing) dYYYY- 7.1 = 4.9
    Answer Memory (Ans)
    The last calculation result obtained is stored in Ans (answer) memory.
    Ans memory contents are updated whenever a new calculation
    result is displayed.
    To divide the result of 3 × 4 by 30
    3 * 4 = 12.
    (Continuing) / 30 =
    123 + 456 = 579 123 + 456 = 579.
    789 – 579 = 210 (Continuing) 789 -G= 210.
    Variables (A, B, C, D, E, F, X, Y)
    (fx-82MS/85MS/300MS/350MS only)
    Your calculator has eight preset variables named A, B, C, D, E, F,
    X, and Y.
