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
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.

• 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

Indicators
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.

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.

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 “

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

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 =

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
