Handling Precautions
• Your calculator is made up of precision components. Never
try to take it apart.
• Avoid dropping your calculator and otherwise subjecting it
to strong impact.
• Do not store the calculator or leave it in areas exposed to
high temperature or humidity, or large amounts of dust.
When exposed to low temperatures, the calculator may
require more time to display results and may even fail to
operate. Correct operation will resume once the calculator
is brought back to normal temperature.
• The display will go blank and keys will not operate during
calculations. When you are operating the keyboard, be sure
to watch the display to make sure that all your key operations are being performed correctly.
• Never leave the dead battery (fx-85B/fx-280) in the battery
compartment. It can leak and damage the unit.
• Avoid using volatile liquids such as thinner or benzine to
clean the unit. Wipe it with a soft cloth, or with a cloth that
has been dipped in a solution of water and a neutral detergent and wring out.
• In no event will the manufacturer and its suppliers be liable
to you or any other person for any damages, expenses,
lost profits, lost savings, or any other damages arising out
of malfunction, repairs, or battery replacement (fx-85B/fx280), or insufficient light. The user should prepare physical
records of data to protect against such data loss.
• Never dispose of battery (fx-85B/fx-280), the liquid crystal
panel, or other components by burning them.
• Before assuming malfunction of the unit, be sure to care—2—
fully reread this manual and ensure that the problem is not
due to low battery power (fx-85B/fx-280) or operational
error.
• The contents of this manual are subject to change without
notice.
• No part of this manual may be reproduced in any form
without the express written consent of the manufacturer.
• Keep this manual on hand for future reference.

kExponential Display Formats
This calculator can display up to 10 digits. Larger values are
automatically displayed using exponential notation. In the
case of decimal value, you can select between two formats
that determine at what point exponential notation is used.
• NORM 1
With NORM 1, exponential notation is automatically used
for integer values with more than 10 digits and decimal values
with more than two decimal places.
• NORM 2
With NORM 2, exponential notation is automatically used
for integer values with more than 10 digits and decimal values
with more than nine decimal places.
— 24 —
To switch between NORM 1 and NORM 2
Press F 9. There is no indication on the display of which
format is currently in effect, but you can determine the setting
by performing the following calculation.
1 \ 200 =
5. –03
0.005
NORM 1 format
NORM 2 format
• All of the examples in this manual show calculation results
using the NORM 1 format.
kWhen you have a problem...
If calculation results are not what you expect or if an error
occurs, perform the following steps.
1. F 0 (COMP mode)
2. F 4 (DEG mode)
3. F 9 (NORM mode)
4. Check the formula you are working with to confirm it is
correct.
5. Enter the correct modes to perform the calculation and
try again.
kMaking Corrections During Calculations
• If you make a mistake when inputting a value (but did not
yet press an operator key), use Q to backspace and delete
input digits one-by-one. Or you can press k to clear the
input entirely and start again.
— 25 —
• In a series of calculations, press k while an intermediate
result is displayed to clear only the last calculation performed.
• To change the operator key (+ , ,, -, \, w , As ,
etc.) you just pressed, simply press the correct operator
key. In this case, the operator of the last key you press is
used, but the operation retains the order of precedence of
the operation for the first key you pressed.
kOverflow or Error Check
The following conditions make further calculation impossible.
a. When a result (whether intermediate or final) or a
t o t a l a c c u mu l a t e d i n m e m o r y i s g r e a t e r t h a n
±9.999999999 1099. (“–E–” indicator appears on the
display.)
b. When function calculations are performed using a value
that exceeds the input range. (“–E–” indicator appears
on the display.)
c. When an illogical operation (such as an attempt to calculate o and σ n while n 0) is performed during statistical
calculations. (“–E–” indicator appears on the display.)
d. When an illegal mathematical operation (such as division
by zero) is performed. (“–E–” indicator appears on display.)
e. The total number of nested parentheses levels exceeds
six, or when more than 18 pairs of parentheses are used.
(“– 1–” indicator appears on the display.)
• To clear any of the above conditions, press t and perform the calculation from the beginning.
— 26 —
• In the case of condition e, you could also press k . This
clears the intermediate result just prior to the overflow, so
you can continue with the calculation from that point.
• No error occurs when the result is within the range of
(11099)to (11099 ). Instead, the display shows all
zeros.
kPower Supply
• fx-82SOLAR/fx-260SOLAR
This calculator is powered by a solar cell that converts available light into electrical power.
Solar Cell Precautions
• The solar cell requires at least 50 lux of light to provide
power.
• If available light is too low, the display may become dim,
calculation functions may become impossible, or the contents of the independent memory may be lost. If this
happens, move to an area with more light.
• fx-85B/fx-280
This calculator is powered by the CASIO TWO- WAY POWER
system, which makes it possible for the calculator to operate
even in total darkness.
• The calculator retains memory contents no matter what
the lighting conditions.
• The TWO-WAY POWER system uses two power sources:
a solar cell and a single G13 Type (SR44 or LR44) battery.
• Weak battery power is indicated when memory contents
spontaneously clear, or when the display darkens under

Important!
Incorrect use of batteries can cause them to burst or leak,
possibly damaging the calculator.
• Be sure to replace the battery at least once every three
years, regardless of how much the calculator is used. Old
batteries may leak, causing serious damage to the interior
of the calculator.
• The battery that comes with the calculator when you purchase it is for testing only. It may not provide full service
life.
• Low bettery power can cause memory contents to become
corrupted or lost completely. Always keep written records
of all important data.
• Always be sure to load the battery with its positive ()
side facing up (so you can see it).
• Never try to charge batteries, take them apart, or allow
them to become shorted. Keep batteries away from direct
flame and heat.
• Keep batteries out of the reach of small children. If
swallowed, consult with your physician immediately.
To replace the battery
1. Remove the screws that hold the
back cover in place, and then remove the cover.
2. Remove the old battery.
3. Install a new battery, making sure
that the positive () side is facing
up (so you can see it).
4. Replace the back cover and
secure it in place with the screws.

kOrder of Operations and Levels
Operations are performed in the following order of precedence.
1. Functions
2. xy, x 1/y, R →P, P →R, nPr, nCr
3. ,
4. ,
• Operations with the same precedence are performed from
left to right, with operations enclosed in parentheses performed first. If parentheses are nested, the operations enclosed in the innermost set of parentheses are performed
first.
• Registers L1 through L6 store operations. There are six registers, so calculations up to six levels can be stored.
• Each level can contain up to three open parentheses, so
parentheses can be nested up to 18 times.
• Example: The following operation uses 4 levels and 5
nested parentheses.
2-O OO3 +4 -OO5 +4
