1. Important Information
• The displays and illustrations (such as key markings) shown in this User’s Guide are for illustrative purposes only, and may differ somewhat from the actual items they represent. • The contents of this manual are subject to change without notice. • In no event shall CASIO Computer Co., Ltd. be liable to anyone for special, collateral, incidental, or consequential damages in connection with or arising out of the purchase or use of this product and items that come with it. Moreover, CASIO Computer Co., Ltd. shall not be liable for any claim of any kind whatsoever by any other party arising out of the use of this product and the items that come with it. • 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

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. RJA521989-001V01 SA0912-A Printed in China

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. * Company and product names used in this manual may be registered trademarks or trademarks of their respective owners.
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.
Input expression

10. Specifying the Calculation Mode
When you want to perform this type of operation: Perform this key operation: General calculations N1(COMP) 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. Norm 1: 10

fraction (d/c) for display of fractions in calculation results.
1Dot 2 Comma Specifies whether to display a dot or a
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.

12. Inputting Expressions and Values
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. 1st Function with parentheses: Pol(

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.
To assign the result of 3 + 5 to variable A
3 + 5 1t(STO) y(A)
