this is not part of the actual key operation you
perform.

• The cursor key is marked with four
arrows, indicating direction, as shown
in the illustration nearby. In this User’s
Guide, cursor key operation is
indicated as f, c, d, and e.

Safety Precautions

Be sure to read the following safety precautions before
using this calculator. Keep this manual handy for later
reference.

Caution

This symbol is used to indicate information that can
result in personal injury or material damage if ignored.

Battery

• After removing the battery from the calculator, put it
in a safe place where it will not get into the hands of
small children and accidentally swallowed.

• Keep batteries out of the reach of small children. If
accidentally swallowed, consult with a physician
immediately.

• Never charge the battery, try to take the battery apart,
or allow the battery to become shorted. Never expose
the battery to direct heat or dispose of it by
incineration.

• Improperly using a battery can cause it to leak and
damage nearby items, and can create the risk of fire
and personal injury.

• Always make sure that the battery’s positive

negative
it into the calculator.

• Remove the battery if you do not plan to use the

calculator for a long time.

• Use only the type of battery specified for this

calculator in this manual.

ends are facing correctly when you load

l

k

and

Disposing of the Calculator

• Never dispose of the calculator by burning it. Doing
so can cause certain components to suddenly burst,
creating the risk of fire and personal injury.

E-4

Handling Precautions

• Be sure to press the O key before using the

calculator for the first time.

• Even if the calculator is operating normally, replace
the battery at least once every three years (FC-200V)
or two years (FC-100V).

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 this unit discharges
slightly during shipment and storage. Because of
this, it may require replacement sooner than the
normal expected battery life.

• Low battery power can cause memory contents to
become corrupted or lost completely. Always keep
written records of all important data.

•Avoid use and storage of the calculator in areas
subjected to temperature 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
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 of the calculator in areas
subjected to large amounts of humidity and dust.

Take care never to leave the calculator where it might be
splashed by water or exposed to large amounts of
humidity or dust. Such conditions can damage internal
circuitry.

• 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 trousers
or other tight-fitting clothing where it might be subjected
to twisting or bending.

• Never try to take the calculator apart.

E-5

• Never press the keys of the calculator with a ballpoint
pen or other pointed object.

• Use a soft, dry cloth to clean the exterior of the
calculator.

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 liquid before
wiping the calculator. Never use thinner, benzene or other
volatile agents to clean the calculator. Doing so can
remove printed markings and can damage the case.

Before Using the Calculator

k 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 below.

k Turning Power On and Off

• Press O to turn on the calculator.

• Press 1A(OFF) to turn off the calculator.

k Adjusting Display Contrast

as they are written. Then simply press the E key to
execute it. The calculator automatically judges the
calculation priority sequence for addition, subtraction,
multiplication, and division, functions, and parentheses.

Example: 2 (5 + 4) – 2 × (–3) =

2(5+4)-

2*y3E

A Inputting a Function with Parenthesis

When you input any of the functions shown below, it is
automatically input with the open parenthesis (
Next, you need to input the argument and the closing
parenthesis (

You can omit one or more closed parentheses that come
at the end of a calculation, immediately before the E key
is pressed. For details, see “Omitting a Final Closed
Parenthesis” on page E-29.

A Displaying a Long Expression

The display can show up to 14 characters at a time.
Inputting the 15th character causes the expression to shift
to the left. At this time, the ] indicator appears to the left
of the expression, indicating that it runs off the left side of
the screen.

Input expression: 1111 + 2222 + 3333 + 444

Displayed portion:

Cursor

• When the ] indicator is displayed, you can scroll left
and view the hidden part by pressing the d key. This
will cause the ' indicator to appear to the right of the
expression. At this time, you can use the e key to scroll
back.

A Number of Input Characters (Bytes)

•You can input up to 99 bytes of data for a single
expression. Basically, each key operation uses up one
byte. A function that requires two key operations to input
(like 11(sin)) also uses only one byte.

E-24

• Normally the input cursor appears as a straight vertical
(

) or horizontal ( ) flashing line on the display screen.

I

When there are 10 or fewer bytes of input remaining in
the current expression, the cursor changes shape to
to let you know. If the I cursor appears, terminate the
expression at a convenient point and calculate the result.

• Each expression in calculation history memory (page
E-33) can contain up to 76 bytes of data. Up to 89 bytes
of data can be assigned to each custom shortcut key
(page E-94).

k Correcting an Expression

This section explains how to correct an expression as you
are inputting it. The procedure you should use depends
on whether you have insert or overwrite selected as the
input mode.

A About the Insert and Overwrite Input Modes

With the insert mode, the displayed characters shift to the
left to make room when you input a new character. With
the overwrite mode, any new character you input replaces
the character at the current cursor position.

• The cursor is a vertical flashing line (
mode is selected. The cursor is a horizontal flashing line
(

) when the overwrite mode is selected.

• The initial default is the insert mode. You can switch
between the insert mode and the overwrite mode by
pressing 1Y(INS).

A Inserting input into a Calculation

Always use the insert mode for this operation. Use d or
e to move the cursor to the location where you want to

insert new input, and then input what you want.

k Displaying the Location of an Error

If an error message (like “Math ERROR” or “Syntax
ERROR”) appears when you press E, press d or e.
This will display the part of the calculation where the error
occurred, with the cursor positioned at the error location.
You can then make necessary corrections.

Example: When you input 14 ÷ 0 × 2 = by mistake instead

of 14 ÷ 10 × 2 =

Insert Mode:

14/0*2E

Press e or d.

This is causing the error.

You can also exit the error screen by pressing A, which

Basic Calculations

This section explains how to perform arithmetic and percent
calculations.

All calculations in this section are performed in the
COMP Mode (g).

k Arithmetic Calculations

Use the +, -, *, and / keys to perform arithmetic
calculations.

Example: 7 × 8 – 4 × 5 = 36

7*8-4*5E

• The calculator automatically judges the calculation priority
sequence. For more information, see “Calculation Priority
Sequence” on page E-134.

A Number of Decimal Places and Number of

Significant Digits

You can specify a fixed number of decimal places and
significant digits for the calculation result.

Example: 1 ÷ 6 =

Initial default setting (Norm1)

FIX

3 decimal places (Fix3)

SCI

3 significant digits (Sci3)
