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 kand negative lends are facing correctly when you load 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.
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.

Inputting Expressions and
Values
kInputting a Calculation Expression
Using Standard Format
Your calculator lets you input calculation expressions just 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 (() character. Next, you need to input the argument and the closing parenthesis ()).
sin(, cos(, tan(, sin–1(, cos–1( , tan–1(, sinh(, cosh(, tanh(, sinh–1(, cosh–1(, tanh–1(, log(, ln(, e^(, 10^(, ^(, '(, 3'(, x'(, Abs(, Pol(, Rec(, Rnd(
Example: sin 30 = z
1. t
2.“sin(” (fc), then E.
3.30)E
•Some commonly used functions can also be input using a direct key operation.
Example: sin 30 =
1.11(sin)
2.30)E
E-23
A Omitting the Multiplication Sign
You can omit the multiplication sign (×) in any of the following cases.
•Before an open parentheses ((): 2 × (5 + 4), etc.
•Before a function with parenthesis: 2 × sin(30), 2 × '(3), etc.
•Before a variable name, constant, or random number: 20 × A, 2 × π, etc.
A Final Closed Parenthesis
You can omit one or more closed parentheses that come at the end of a calculation, immediately before the Ekey 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 ekey 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 (I) or horizontal ( ) flashing line on the display screen. When there are 10 or fewer bytes of input remaining in the current expression, the cursor changes shape to I to let you know. If the I cursor appears, terminate the expression at a convenient point and calculate the result.
kCorrecting 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 (I) when the insert 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).
AChanging the Character or Function You Just Input
Example: To correct the expression 369 × 13 so it becomes 369 × 12
369*13
Y

A Deleting a Character or Function
Example: To correct the expression 369 × × 12 so it becomes 369 × 12
Insert Mode:

Overwrite Mode:
369**12

A Correcting a Calculation
Example: To correct cos(60) so it becomes sin(60)
Insert Mode:
12(cos)60)
dddY
11(sin)
Overwrite Mode: 12(cos)60)
dddd
11(sin)
E-26
A Inserting input into a Calculation
Always use the insert mode for this operation. Use dor eto move the cursor to the location where you want to insert new input, and then input what you want.
kDisplaying the Location of an Error
If an error message (like “Math ERROR” or “Syntax ERROR”) appears when you press E, press dor 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 eor d.
This is causing the error.
d1
E
You can also exit the error screen by pressing A, which clears the calculation.

Basic Calculations
This section explains how to perform arithmetic and percent calculations.
All calculations in this section are performed in the COMP Mode (g).
kArithmetic 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)
