Safety PrecautionsBe 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. Ifaccidently swallowed, consult with a physician im-

mediately.

Never charge batteries, try to take batteries apart, orallow 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 thatcan cause damage to nearby items and creates the

possibility of fire and personal injury.

Always make sure that a batterys positive kandnegative lsides are facing correctly when youload 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.

tion of the calculator. Never leave the dead battery in the

calculator.

The battery that comes with the calculator when youpurchase it is for testing only. It may not provide full

service life.

Low battery power can cause memory contents tobecome corrupted or lost completely. Always keep

written records of all important data.


5/36

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 calculators case, and

damage to internal circuitry.

Avoid use and storage in areas subjected to largeamounts of humidity and dust.

Take 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-pointpen 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.

k Input Capacity

The memory area used for calculation input can hold 79

steps. Whenever you input the 73rd step of any calcu-

lation, the cursor changes from _ to k to let you knowmemory is running low. If you still need to input more,

you should divide your calculation into two or more parts.

kMaking Corrections During Input

Useeandrto move the cursor to the location youwant.

Press[to delete the number or function at the current

cursor position.

PressAKto change to an insert cursort. Inputtingsomething while the insert cursor is on the display in-

serts the input at the insert cursor position. Presse,r,AK, or=returns to the normal cur-

sor from the insert cursor.

kReplay Function

Pressingrorerecalls the last calculation you per-formed. You can then make any changes you want in the

calculation and re-execute it.

Pressingtdoes not clear Replay memory, so you can

recall the last calculation even after you presst.

Replay memory is cleared whenever you start a new

calculation, change to another mode, or turn off power.

kError Locator

Pressing r or eafter an error occurs displays the

calculation with the cursor positioned at the location

where the error occurred.

kExponential Display Formats

This calculator can display up to 10 digits. Larger values

are automatically displayed using exponential notation. In

the case of decimal values, you can select between twoformats that determine at what point exponential notation

is used. Press FFFF31 (or 2) to selectNORM 1 or NORM 2 (fx-85W). For other models, press

FFF31(or2). NORM 1With 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 2With NORM 2, exponential notation is automatically used

for integer values with more than 10 digits and decimalvalues with more than nine decimal places.

All of the examples in this manual show calculation re-

sults using the NORM 1 format.

kAnswer Memory Whenever you press=after inputting values or an ex-

pression, the calculated result is automatically stored in

Answer Memory. You can recall Answer Memory con-

tents by pressingg.

Answer Memory can store up to 12 digits for the mantissa

and two digits for the exponent. Answer Memory contents are not changed if the opera-

tion performed by any of the above key operations re-

sults in an error.

Formula Memory (fx-85W)

Formula memory lets you input a single formula in

memory, and then input values for the formula's variablesto calculate results.

Memory can hold a single formula, up to 79 steps long.

This function can be used in the COMP mode only.

Note that the formula is actually stored in memory when

you press theCkey in the sequence below.

Example: To save the following formula, recall it, andthen use it to calculate a result: Y = X2+ 3X 12

Input the formula.

Formula memory is cleared whenever you start a new

calculation, change to another mode, or turn off power.

Base-n

Calculations(fx-85W)

In addition to decimal values, calculations can be per-

formed using binary, octal and hexadecimal values.

You can specify the default number system to be ap-

plied to all input and displayed values, and the number

system for individual values you input.

You cannot use scientific functions in binary, octal, deci-

mal, and hexadecimal calculations. You cannot input val-

ues that include decimal part and an exponent.

If you input a value that includes a decimal part, the unit

automatically cuts off the decimal part.

Negative binary, octal, and hexadecimal values are pro-

duced by taking the two's complement.

kPower SupplyThe type of battery you should use depends on the model

number of your calculator.

The TWO WAY POWER system actually has two power

supplies: a solar cell and a G13 Type (LR44) button bat-

tery. Normally, calculators equipped with a solar cell alone

can operate only when relatively bright light is present.

The TWO WAY POWER system, however, lets you con-tinue to use the calculator as long as there is enough light

to read the display.

Replacing the Battery

Either of the following symptoms indicates battery power

is low, and that the battery should be replaced. Display figures are dim and difficult to read in areas

where there is little light available.

Nothing appears on the display when you press the

5key.

To replace the battery1 Remove the six screws that

hold the back cover in placeand then remove the backcover.

2 Remove the old battery.

3 Wipe off the sides of new bat-tery with a dry, soft cloth. Loadit into the unit with the posi-tivekside facing up (so youcan see it).

4 Replace the back cover and

secure it in place with the sixscrews.

5 Press5to turn power on. Besure not to skip this step.
