Safety Precautions
Be sure to read the following safety precautions before
using this calculator. Keep this manual handy for later ref-
erence.
Caution
This symbol is used to indicate information that can
result in personal injury or material damage if ignored.
Batteries
•After removing the batteries from the calculator, put
them in a safe place where there is no danger of
them getting into the hands of small children and
accidently swallowed.
•Keep batteries out of the reach of small children. If
accidently swallowed, consult with a physician im-
mediately.
•Never charge batteries, try to take batteries apart, or
allow batteries to become shorted. Never expose bat-
teries to direct heat or dispose of them by incinera-
tion.
•Misuse of batteries can cause them to leak acid that
can cause damage to nearby items and creates the
possibility of fire and personal injury.
•Always make sure that a battery’s positive kand
negative lsides are facing correctly when you
load it into the calculator.
•Remove the batteries if you do not plan to use the
calculator for a long time.
•Use only the type of batteries specified for this cal-
culator in this manual.
Disposing of the Calculator
•Never dispose of the calculator by burning it. Doing
so can cause certain components to suddenly burst,
creating the danger of fire and personal injury.
E-2
•The displays and illustrations (such as key markings)
shown in this User’s Guide are for illustrative pur-
poses 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 con-
sequential damages in connection with or arising out
of the purchase or use of these materials. Moreover,
CASIO Computer Co., Ltd. shall not be liable for any

Handling Precautions
•Be sure to press the P button on the back of the cal-
culator (step 6on page 29) before using it for the
first time (fx-350TL).
•Be sure to press the 5key before using the calcu-
lator for the first time (fx-85W/fx-85WA/fx-300W).
•Even if the calculator is operating normally, replace
the battery at least once every three years.
Dead battery can leak, causing damage to and malfunc-
tion of the calculator. Never leave the dead battery in 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 battery power can cause memory contents to
become corrupted or lost completely. Always keep
written records of all important data.
E-3
•Avoid use and storage in areas subjected to tempera-
ture extremes.
Very low temperatures can cause slow display response,
total failure of the display, and shortening of battery life.
Also avoid leaving the calculator in direct sunlight, near
a window, near a heater or anywhere else it might be-
come exposed to very high temperatures. Heat can cause
discoloration or deformation of the calculator’s case, and
damage to internal circuitry.
•Avoid use and storage in areas subjected to large
amounts of humidity and dust.
Ta k e care never to leave the calculator where it might be
splashed by water or exposed to large amounts of hu-
midity or dust. Such elements can damage internal cir-
cuitry.
•Never drop the calculator or otherwise subject it to
strong impact.
•Never twist or bend the calculator.
Avoid carrying the calculator in the pocket of your trou-
sers or other tight-fitting clothing where it might be sub-
jected to twisting or bending.
•Never try to take the calculator apart.
•Never press the keys of the calculator with a ball-point
pen or other pointed object.
•Use a soft, dry cloth to clean the exterior of the unit.
If the calculator becomes very dirty, wipe it off with a
cloth moistened in a weak solution of water and a mild
neutral household detergent. Wring out all excess mois-
ture before wiping the calculator. Never use thinner, ben-
zine or other volatile agents to clean the calculator. Do-
ing so can remove printed markings and damage the
case.
