• Even if the calculator is operating normally, replace the battery at least once a year.
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.
• Do not use an oxyride battery or any other type of nickel-based primary battery with
this product. Incompatibility between such batteries and product specifications can
result in shorter battery life and product malfunction.
• 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.
• 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.

Number of Input Characters (Bytes)
A
As you input a mathematical expression, it is stored in memory called an “input area,”
which has a capacity of 127 bytes. This means you can input up to 127 bytes for a single
mathematical expression.
When linear display is selected as the display format, each function normally uses one or
two bytes of memory. With the natural display format, each function use four or more bytes
of memory. For more information, see “Inputting Calculation Expressions Using Natural
Display” on page 17.
Normally, the cursor that indicates the current input location on the display is either a
fl ashing vertical bar ( ) or horizontal bar ( ). When the remaining capacity of the input area
|
is 10 bytes or less, the cursor changes to a flashing box ( ).
k
If this happens, stop input of the current expression at some suitable location and calculate
its result.
Using Natural Display
k
While natural display is selected as the display format (page 11), you can input fractions
and some scientific functions just as they are written.
Natural Display Basics
A
The table below lists the types of scientific functions that you can input using natural display
format.
• The *1 column shows the number of bytes of memory used up by each scientific function.
See “Number of Input Characters (Bytes)” (page 16) for more information.
• For information about the *2 column, see “Using Values and Expressions as Arguments”

display screens (31 dots × 2). Further input will become impossible if the height of the
calculation you are inputting exceeds the allowable limit.
• Nesting of functions and parentheses is allowed. Further input will become impossible if
you nest too many functions and/or parentheses. If this happens, divide the calculation
into multiple parts and calculate each part separately.

Using Values and Expressions as Arguments
A
When inputting with natural display, in certain cases you can use a value or an expression
that is enclosed in parentheses that you have already input as the argument of a scientific
function (such as
), the numerator of a fraction, etc. For the sake of explanation here,
'
a natural display function that supports the use of previously input values or parenthetical
expressions is called an “insertable natural display function”.
Example: To insert the natural display function
into the parenthetical expression in the
'
following calculation: 1 + (2 + 3) + 4
(Move the cursor immediately to the left of
the parenthetical expression.)

!
Note
• Not all natural display functions are insertable. Only the scientific functions for which
“Yes” appears in the column of the table under “Scientific Functions that Support Natural
Display” (page 16) are insertable.
• The cursor can be immediately to the left of a parenthetical expression, a numeric value,
or a fraction. Inserting an insertable function will make the parenthetical expression, value,
or fraction the argument of the inserted function.
• If the cursor is located immediately to the left of a scientific function, the entire function
becomes the argument of the inserted function.

Editing a Calculation
k
Insert Mode and Overwrite Mode
A
The calculator has two input modes. The insert mode inserts your input at the cursor
location, shifting anything to the right of the cursor to make room. The overwrite mode
replaces the key operation at the cursor location with your input.
Only the insert mode is available when natural display is selected as the display format.You
cannot change to the overwrite mode. When linear display is selected as the display format,
you can choose either the insert mode or overwrite mode for input.

Calculator Memory Operations
Your calculator includes the types of memory described below, which you can use for
storage and recall of values.
Memory Name
Description
Answer Memory contains the result of the last calculation you
performed.
Answer Memory
Independent memory comes in handy when adding or subtracting
multiple calculation results.
Independent Memory
Variables
The letters A through Z can be assigned different values
individually and used in calculations. Note that variable M is also
used for storing independent memory values.
You can create extra variables when you need storage for more
values than provided by the 26 letters from A through Z.You can
reserve up to 2372 extra variables, which are named Z[1], Z[2],
etc.
Extra Variables
The following literal variables are used by the calculator’s built-in
formulas or user formulas.
• Lower-cast alphabetic characters: a through z
• Greek characters: α through ω, Α through Ω
• Subscripted alphabetic and Greek characters: A1, a0, ωt, ∆x, etc.
For details about built-in formulas and formula variables, see

Using Answer Memory (Ans)
k
The result of any new calculation you perform on the calculator is stored automatically in
Answer Memory (Ans).
Automatic Insertion of Ans in Consecutive Calculations
A
If you start a new calculation while the result of a previous calculation is still on the display,
the calculator will insert Ans into the applicable location of the new calculation automatically.
Example 1: To divide the result of 3 × 4 by 30
b

Pressing
inputs Ans automatically.
/
Example 2: To determine the square root of the result of 32 + 42
b

!E
Note
• As in the above examples, the calculator automatically inserts Ans as the argument of
any calculation operator or scientific function you input while a calculation result is on the
display.
• In the case of a function with a parenthetical argument (page 15), Ans automatically
becomes the argument only in the case that you input the function alone and then
press
. Note, however, that with natural display Ans may not become the argument
E
automatically when using a function with a parenthetical argument.
• Basically, Ans is inserted automatically only when the result of the previous calculation is
still on the display, immediately after you executed the calculation that produced it. If you
want to insert Ans after clearing the display by pressing
, press

Reserving Variable Memory
If you find that the calculator’s default variables (A through Z) are not enough for your
purposes, you can reserve variable memory and create “extra variables” for storage of
value.
Extra variables work like array variables of an array named “Z” when assigning or recalling
their values. An extra variable name consists of the letter “Z” followed by a value in brackets,
like Z[5].
User Memory Area
k
Your calculator has a 28500-byte user memory area that you can use to reserve variable
memory and add extra variables.
Important!
• You can perform the procedure to reserve variable memory in the COMP Mode or in a
COMP Mode program. All of the sample operations in this section are performed in the
COMP Mode (
N1
).
• The 28500-byte user memory is used for storage of extra variables and programs. This
means that increasing the number of extra variables reduces the amount of memory
available for storing programs. So also, storing programs in memory reduces the amount
of memory available for storing extra variables.

the extra variables.

(Z)
oS5
([)
Si 10S6
(])
E
Note
Reserving variable memory uses up a basic 26 bytes, plus 12 bytes for each of the extra
variables that you add. Note that storing a complex number of an extra variable uses up 22
bytes. Adding 10 extra variables as shown above, for example, uses up 26 + (12 × 10) = 146
bytes of the user memory area. Since user memory has a total capacity of 28500 bytes, the
limit on the number of extra variables you can add is 2372 (assuming you do not have any
complex numbers assigned to the extra variables).
Using Extra Variables
k
After creating extra variables, you can assign values to them and insert them into
calculations just as you do with the default valuables (from A through Z). Just remember that
extra variable names consist of the letter “Z” followed by a value in brackets, like Z[5].
Note
• The closing bracket ( ] ) of the extra variable name can be omitted.
• In place of a value inside the brackets of an extra variable name, you can use a calculation
expression or a default array name (A to Z).
• Note that the value in the brackets of an extra variable name must be in the range of
1 and the number of extra variables that have been added. Trying to use a value that
exceeds the number of extra variables will cause an error.
Assigning a Value or Calculation Result to an Extra Variable
A
You can assign a value to an extra variable using the following command syntax: {value or
expression} Z[{extra variable value}]
.

• For periodic functions, and for positive and negative f(x) values due to the region of
integration being used
Divide the integration into parts for each period, or between positive and negative
parts, obtain integration values for each, and then add the values.

Matrix calculations are performed by first storing the matrices in one of six matrix memory
areas named Mat A through Mat F, and then using the matrix area variables to perform the

Matrix calculation results are displayed on a Mat Ans screen.
About the Mat Ans Screen
k
Any calculation result that is a matrix is stored in Matrix Answer memory named “Mat Ans”.
You can use the Mat Ans screen to view the matrix that is currently stored in Mat Ans.
• Each of cells on the Mat Ans screen shows up to six digits of the value currently stored in
the cell.
• To check the value stored in a cell, use the cursor keys to move the highlighting to the cell.
This will cause the full value contained to appear in the value display area at the bottom of
the screen.
• If a cell contains a fraction or sexagesimal value, the applicable cell on the Mat Ans
screen will show the decimal format equivalent. When you move the highlighting to the
cell, the value will appear in the applicable fraction or sexagesimal format in the value
display area.
• Though the Mat Ans screen looks very similar to the matrix editor screen, you cannot edit
a matrix on the Mat Ans screen.
• Pressing

Matrix Calculations” (page 62).
Inputting and Editing Matrix Data
k
You can input data for up to six matrices, named Mat A through Mat F, and then use the
matrix names as variables in calculations. There are two methods you can use to input data
into a matrix: using the matrix editor screen and using the value assignment command ( ).

The calculator’s initial default setting is FreqOff.You can select the input method you want to
use with the setup screen statistical frequency setting (page 13).
The STAT editor screens include a FREQ column when statistical frequency is turned on
(FreqOn). There is no FREQ column when statistical frequency is turned off (FreqOff).

Inputting Sample Data

The following example shows how to input the following sample data in the SD Mode.
Class Value (X)
Frequency (FREQ)
24.5
25.5
26.5
4
6
2
Enter the SD Mode:
(SD)
N3
Input the class values in the X column:
24.5E25.5E26.5E
The initial default for all frequencies is 1.
Move the cursor to the top cell of the FREQ column:
ce
Input the frequency values in the FREQ column:
4E6E2E
The only difference when inputting sample data in the REG Mode is that the STAT editor
screen has three columns named X, Y, and FREQ.
Note
• In the SD Mode, one set of sample data consists of an X value and FREQ value, while
one set of REG Mode sample data consists of an X value, Y value, and FREQ value.
Whenever you start input of a sample data set by inputting a value for any one of its
columns on the STAT editor screen, the remaining column(s) in the same sample data set
change(s) to their initial defaults (X = 0, Y = 0, FREQ = 1).
• Inputting a calculation expression into a cell and pressing

E
• In both the SD Mode and REG Mode, you can input up to 199 STAT editor lines of sample
data.
• Sample data you input is retained in memory until you delete it or reset the calculator.
Changing to another calculation mode, changing the statistical frequency setting, or
turning off the calculator does not affect sample data.

E-73
• Even though Y-data is not used and there is no indication of Y-data on the screen in the
SD Mode, the calculator still maintains a Y-value (always zero) internally for each X-data.
Because of this, if you perform a statistical calculation operation that involves Y-data (such
as Σy) after inputting single-variable data in the SD Mode, the calculator will produce a
result without displaying an error.
Editing Sample Data
A
You can use the procedures in this section to perform the following STAT editor screen
editing operations: replace cell contents, insert a line, insert a cell, delete a cell, and delete
all STAT editor screen data.

CALC
CALC makes it easy to solve an expression that contains variables. After you input the
expression, simply enter values for the variables to calculate the result.You can change the
values of the variables as many times as you like.
CALC can be used only in the COMP Mode (
N1
).
Using CALC
k
Inputting an expression that contains variables and pressing the
key displays a “value
s
assignment screen”, which you can use to assign values to each variable. After inputting the
values, press to execute the calculation.
E
Performing Calculation with CALC
A
Important!
• In the CALC mode, a calculation that contains variables can use variables A through Z
only. Extra variables (Z[1], Z[2], etc.) cannot be used as variables. If you try to use an
extra variable in a calculation in the CALC mode, it will be treated as a constant using the
current value assigned to it.

Performing Calculation with a User Formula
A
Since user formulas are saved as programs, they are executed using the same procedures
as those for program execution. For details about the procedure, see “Running a Program
from the Prog List or Fmla List Screen” (page 109).
Operation (assignment of values to variables) after executing a user formula is the same as
those for the built-in formulas.
Program Mode (PROG)
You can use the PROG Mode (
N5
) to create and store programs for calculations you
need to perform on a regular basis.You can assign a name to a program when you store it,
which simplifies recall, editing, deletion, and other file management operations.

Program Mode Overview
k
Specifying a Program Run Mode
A
Whenever you create a new program, you need to specify its “run mode”, which is the
calculator mode where the program will run. There are three run modes: COMP, BASE-N,
and Formula.
When your program contains this:
Select this run mode:
Calculations performed in the COMP Mode (including
matrix, complex number, and statistical calculations)
COMP
Calculations performed in the BASE-N Mode
Built-in formula type calculations
BASE-N
Formula
The run mode of each program is indicated on file list screens (page 111). There are two
types of file list screens, a “Prog List” screen that shows programs whose run mode is
COMP or BASE-N, and the “Fmla List” screen that shows programs whose run mode is
Formula.
Prog List screen
Fmla List screen
File name
Run modes (No indicator: COMP, BN: BASE-N, FM: Formula)
The examples use COMP or BASE-N as the run mode. For information about programs (user
formulas) that use Formula as the run mode, see “User Formulas” (page 102).
Program Memory
A
Your calculator has 28500 bytes of program memory.
Important!
The 28500-byte user memory is used for storage of extra variables and programs. This
means that increasing the number of extra variables reduces the amount of memory
available for storing programs. So also, storing programs in memory reduces the amount of
memory available for storing extra variables.

Control Structure Commands: If Statements
A
The If statement is used to control program execution branching according to whether the
expression following If (which is the branching condition) is true or false.
If Statement Precautions
• An If statement must always be accompanied by a Then statement. Using an If without a
corresponding Then will result in a Syntax ERROR.
• An expression, Return, or Stop command can be used for the <expression*> following
Then and Else.
If ~ Then (~ Else) ~ IfEnd
Syntax
If <conditional expression> : Then <expression*> : Else <expression*> :
IfEnd : <statement> : ...
Function
• The statements following Then are executed up to Else, and then the
statements following IfEnd are executed when the conditional statement
following If is true. The statements following Else and then the statements
following IfEnd are executed when the conditional statement following If is
false.
• “Else<expression>” may be omitted.
• Always include the “IfEnd”. Omitting it will not cause an error, but certain
program contents can cause unexpected execution results by everything
after the If statement.
Example 1
Example 2
? → A : If A < 10 : Then 10A
Else 9A
IfEnd : Ans×1.05
^
^
? → A : If A > 0 : Then A×10 → A : IfEnd : Ans×1.05
Control Structure Commands: For Statements
A
The For statement repeats execution of the statements between For and Next as long as
the value assigned to the control variable is within the specified range.
For Statement Precautions
A For statement must always be accompanied by a Next statement. Using a For without a
corresponding Next will result in a Syntax ERROR.
For ~ To ~ Next
(COMP)
Syntax
For <expression (start value)> → <variable (control variable)> To <expression
(end value)> : <statement> : ... <statement> : Next : ...
Function
Execution of the statements from For to Next repeats as the control variable
is incremented by 1 with each execution, starting from the starting value.
When the value of the control value reaches the ending value, execution
jumps to the statement following Next. Program execution stops if there is no
statement following Next.
Example
For 1 → A To 10 : A2 → B : B
Next

For ~ To ~ Step ~ Next
(COMP)
Syntax
For <expression (start value)> → <variable (control variable) >
To <expression (end value)> Step <expression (step value)> : <statement> :
... <statement> : Next : ...
Function
Execution of the statements from For to Next repeats as the control variable
is incremented by the step amount with each execution, starting from the
starting value. Except for that, this command is the same as For~To~Next.
Example
For 1 → A To 10 Step 0.5 : A2 → B : B
Next
^
Control Structure Commands:While Statements
A
While ~ WhileEnd
(COMP)
Syntax
Function
While <conditional statement> : <statement> : ... <statement> : WhileEnd : ...
The statements from While to WhileEnd are repeated while the conditional
expression following While is true (non-zero). When the conditional
expression following While becomes false (0), the statement following
WhileEnd is executed.
Example
Note
? → A : While A < 10 : A2
A + 1 → A : WhileEnd : A ÷ 2
^
• If the condition of the While statement is false the first time this command
is executed, execution jumps directly to the statement following WhileEnd
without executing the statements from While to WhileEnd even once.
• To input the WhileEnd command, select “W·End” on the function menu.
Do ~ LpWhile
(COMP)
Syntax Do : <statement> : ... <statement> : LpWhile <conditional statement>
Function
The statements from Do to LpWhile are repeated while the conditional
expression following LpWhile is true (non-zero). Since the condition is
assessed following execution of LpWhile, the statements from Do to LpWhile
are executed at least once.
Example
Note
Do : ? → A : A × 2 → B : B
LpWhile B > 10
^
To input the LpWhile command, select “Lp·W” on the function menu.

E-117
Function
Executes another separate program (subroutine) from the current program
(main routine).
Subroutines
Main Routine
Level 1
Level 2
Level 3
Level 4
• A subroutine can be called up as many times as you like from the main
routine. A subroutine can be called up from any number of main routines.
• Execution of the Prog "file name" command jumps to the subroutine and
runs it from the beginning. When the end of the subroutine is reached,
processing jumps back to the main routine and continues from the
statement following the Prog "file name" command.
• You can use the Prog command inside of a subroutine to cause process
to jump to another subroutine. This is called “nesting”.You can nest
subroutines up to 10 levels. Attempting to nest more than 10 levels causes
an error (Ne ERROR).
• Note that a Goto ~ Lbl jump within a subroutine can be performed only
within the same subroutine.
• An error (Go ERROR) will occur if the program specified by the Prog "file
name" command cannot be found for some reason.
Important!
• A program that uses Formula as the run mode cannot be used as a
subroutine.
• The main routine and the subroutine must be the same run mode. This
means, for example, that a subroutine that is a program whose run mode
is BASE-N cannot be called by a main routine that is a program whose run
mode is COMP.
Example
Note
Ans → A : Prog "SUB1" : Prog "SUB2"
For information about using the Prog command outside of the PROG Mode,
see “Using the Prog Command to Run a Program” (page 110).
Program Control Commands
A
Break
(COMP)
Syntax
... : Break : ...
Function
This command forces a break in a For, While, or Do loop, and jumps to the
next command. Normally, this command is used inside of a Then statement
in order to apply a Break condition.
Example
While A > 0 : If A > 2 : Then Break : IfEnd : WhileEnd : A

Note
•
If a calculation contains a negative value, you may need to enclose the negative value in
parentheses. If you want to square the value –2, for example, you need to input: (–2)2. This is
because x2 is a function preceded by a value (Priority 2, above), whose priority is greater than
the negative sign, which is a prefix symbol (Priority 4).
–22 = –4
-2wE
(–2)2 = 4
(-2)wE

•
Multiplication and division, and multiplication where the sign is omitted are the same priority
(Priority 7), so these operations are performed from left to right when both types are mixed in the
same calculation. Enclosing an operation in parentheses causes it to be performed first, so the
use of parentheses can result in different calculation results.

result in accumulation of errors that occur within each individual calculation.
Errors are cumulative and tend to be large in the vicinity of a function’s singular point and
inflection point.

Normally when you replace the calculator’s battery, it stores its current memory contents in
fl ash memory and restores them after battery replacement is complete. If you continue to use
the calculator without replacing the battery after the above message appears, the calculator will
eventually lose its ability to store data to flash memory. When this happens, the calculator will not
be able to restore memory contents after battery replacement.
Power Requirements
Your calculator runs on a single AAA-size alkaline battery (LR03).
Using the wrong type of battery can result in greatly reduced battery life and calculator
malfunction.
Replacing the Battery
A
The Low Battery message will appear when battery power goes low. When this happens,
stop using the calculator, turn it off, and replace its battery.You should also regularly replace
the battery at least once a year, even if the calculator is operating normally.
Note
Your calculator uses flash memory to store data, so memory data is not lost when you
remove the battery.
1. Press
(OFF) to turn off the calculator.
1o
• Be sure to turn off the calculator before replacing the battery. Replacing the battery with
power on will cause data in memory to be deleted.
• Close the calculator cover before replacing the battery. This will help prevent turning on
calculator power accidentally.
2. On the back of the calculator, loosen the screw that
secures the battery cover in place.
• The screw is designed so it can be loosened, without
being removed from the cover. Loosen the screw as much
as it can be loosened.
3. Slide the battery cover in the direction indicated by the
arrow to remove it.
4. Remove the old battery.
5. Referring to the illustration inside the battery compartment,
load a new battery so its positive
