Handling Precautions
• Your ClassPad is made of precision components. Never try to take it apart.
• Avoid dropping your ClassPad and subjecting it to strong impact.
• Do not store the ClassPad or leave it in areas exposed to high temperatures or humidity, or
large amounts of dust. When exposed to low temperatures, the ClassPad may require more
time to display results and may even fail to operate. Correct operation will resume once the
ClassPad is brought back to normal temperature.
• Replace the batteries once every one year regardless of how much the ClassPad is used during
that period. Never leave dead batteries in the battery compartment. They can leak and damage
the ClassPad.
• 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.
• Keep batteries out of the reach of small children. If swallowed, consult a physician immediately.
• Avoid using volatile liquids such as thinners or benzine to clean the ClassPad. Wipe it with a
soft, dry cloth, or with a cloth that has been moistened with a solution of water and a neutral
detergent and wrung out.
• Always be gentle when wiping dust off the display to avoid scratching it.
• In no event will the manufacturer and its suppliers be liable to you or any other person for any
damages, expenses, lost profits, lost savings or any other damages caused by loss of data
and/or formulas arising out of malfunction, repairs, or battery replacement. It is up to you to
prepare physical records of data to protect against such data loss.
• Never dispose of batteries, the liquid crystal panel, or other components by burning them.
• When the “Batteries are extremely low!” message appears on the display, replace the batteries
as soon as possible.
• Be sure to turn off the ClassPad before replacing the batteries.
• If the ClassPad is exposed to a strong electrostatic charge, its memory contents may be
damaged or the keys may stop working. In such a case, perform the reset operation to clear the
memory and restore normal key operation.
• If the ClassPad stops operating correctly for some reason, use the stylus to press the P button
on the back of the ClassPad. Note, however, that this clears all the data in ClassPad memory.
• Note that strong vibration or impact during program execution can cause execution to stop or
can damage the ClassPad’s memory contents.
• Using the ClassPad near a television or radio can cause interference with TV or radio reception.
• Before assuming malfunction of the ClassPad, be sure to carefully reread this user’s guide to
ensure that the problem is not due to insufficient battery power, programming, or operational
errors.
• Make sure nothing gets between the front cover and the touch screen. Besides creating the
risk of scratching the touch screen, an object coming into contact with the screen can cause the
power to turn on and run down the batteries.
• Always attach the front cover to the ClassPad whenever you are not using it. Otherwise,
accidental operation of the touch screen or the 0key can cause the power to turn on and
run down the batteries.

Be sure to keep physical records of all important data!
Low battery power or incorrect replacement of the batteries that power the ClassPad can cause
the data stored in memory to be corrupted or even lost entirely. Stored data can also be affected
by strong electrostatic charge or strong impact. It is up to you to keep back up copies of data to
protect against its loss.
Backing Up Data
Your ClassPad comes bundled with a special USB cable and FA-CP1 software, which you can
use to backup data to a computer running Windows® 98 SE, Windows® Me, Windows® XP,
Windows® 2000, or Windows Vista®.
• The FA-CP1 software is on the CD-ROM.

General Guide
Using the Stylus
Most value and formula input, command executions, and other operations can be performed
using the stylus.
Things you can do with the stylus
I
• This is equivalent to clicking with a mouse.
• To perform a tap operation, tap lightly with the
stylus on the ClassPad’s touch screen.
• Tapping is used to display a menu, execute an
on-screen button operation, make a window
active, etc.
Tap
• This is equivalent to dragging with a mouse.
• To perform a drag operation, hold the tip of the
stylus on the touch screen as you move the
stylus to another location.
• Dragging is used to change the setting of a
slider or some other on-screen controller, to
move a formula, etc.
Drag
Important!
• Be sure that you do not misplace or lose the stylus. Keep the stylus in the holder on the
right side of the ClassPad whenever you are not using it.
• Do not allow the tip of the stylus to become damaged. Using a stylus with a damaged tip to
perform touch screen operations can damage the touch screen.
• Use only the stylus that comes with your ClassPad or some other similar instrument to
perform touch screen operations. Never use a pen, pencil or other writing instrument, which
can damage the touch screen.

Turning Power On and Off
1-2 Turning Power On and Off
Turning Power On
You can turn on the ClassPad either by pressing the 0key or by tapping the touch
screen with the stylus.
• Turning on the ClassPad (while it is in the sleep state) displays the window that was on the
display when you last turned it off. See “Resume Function” below.
• Note that you need to perform a few initial setup operations when you turn on the ClassPad
the first time after purchasing it. For details, see “Getting Ready” at the beginning of this
user’s guide (page 1).
Turning Power Off
To turn off the ClassPad, hold down the 0key for about two seconds, or until the ending
screen appears. For details about the ending screen, see “16-11 Specifying the Ending
Screen Image”.
Important!
The ClassPad also has an Auto Power Off feature. This feature automatically turns the
ClassPad off when it is idle for a specified amount of time. For details, see “Auto Power Off”
on page 16-6-1.
Though the screen of your ClassPad goes blank when you turn it off, it continues to perform
certain internal processes for a short while. Because of this, you should always wait for a
minute or so after turning off the ClassPad before turning it back on again.
Resume Function
Any time the ClassPad powers down (because you turn off power or because of Auto Power
Off), the Resume function automatically backs up its current operational status and any data
in RAM, and the ClassPad enters a “sleep state”. If you turn ClassPad power back on while
it is in the sleep state, the Resume function restores the backed up operational status and
RAM data.
20060301
1-2-2
Turning Power On and Off
Limiting the Duration of the Sleep State
You can use the [Power Save Mode] setting (page 16-6-1) to limit the duration of the sleep
state that is entered by the Resume function. If you have “1 day” specified for [Power Save
Mode], for example, the ClassPad remains in the sleep state for one day after power is turned
off. After that, the ClassPad powers down completely, which deletes all data that was backed
up by the Resume function.
The following describes the difference between powering up from the sleep state and
powering up after the ClassPad powers down completely.
Powering Up from the Sleep State
I
Power comes on immediately, with all data backed up by the Resume function restored.
Powering Up after Complete Power Down
I
1. Press the 0key or tap the ClassPad screen.
• This causes the ClassPad to perform it startup routine, which takes a little time to
complete.
2. The application menu will appear after you finish the touch panel alignment procedure.

Advanced Soft Keyboard Operations
As explained in “Using the Soft Keyboard” on page 1-6-1, there are four soft keyboard types:
the math (mth) keyboard, the alphabet (abc) keyboard, the catalog (cat) keyboard, and the
2D math (2D) keyboard. This section provides more detailed information about soft keyboard
operations and the various key sets available with each soft keyboard.
• All of the explanations in this section start from the initial key set of each keyboard.
Using the Math (mth) Keyboard
I
The math (mth) keyboard is for inputting calculation expressions and numeric expressions. In
addition to the initial math (mth) key set, you can also select from among four other key sets
named

Input
To input a series of multiple characters
S
A series of multiple characters (like “list1”) can be used for variable names, program
commands, comment text, etc. Always use the alphabet (abc) keyboard when you want to
input a series of characters.
Example:
ꢃ?@AU
You can also use the alphabet (abc) keyboard to input single-character variable names.
To do so, simply input a single character, or follow a single character with a mathematical
operator.
Example: ꢖ ꢁ
ꢃ?
@
AU
Tip
• A single-character variable you input using the alphabet (abc) keyboard is identical to a single-
character variable you input using the math (mth) keyboard.
Using the Catalog (cat) Keyboard
I
The “Form” menu of the catalog keyboard lets you select one of the following five categories:
[Func] (built-in functions on pages 2-4-2 and 2-8-1), [Cmd] (built-in commands and operators
on pages 1-7-4 and 12-6-1), [Sys] (system variables on page -7-1), [User] (user-defined
A
functions on page 12-5-1), and [All] (all commands, functions, etc.). After selecting a
category, you can choose the item you want from the alphabetized list that appears on the
catalog (cat) keyboard.
Tip
• Note that user-defined variables and user-defined programs cannot be input using the catalog (cat)
keyboard. Use the Variable Manager (page 1-8-1) instead.
• A user-defined function must be stored in the “library” folder to appear in the catalog (cat)
keyboard list when the [User] category is selected.

Variables and Folders
1-7 Variables and Folders
Your ClassPad lets you register text strings as variables. You can then use a variable to
store a value, expression, string, list, matrix, etc. A variable can be recalled by a calculation
to access its contents.
Variables are stored in folders. In addition to the default folders that are provided
automatically, you can also create your own user folders. You can create user folders as
required to group variables by type or any other criteria.
Folder Types
Your ClassPad stores variables in one of four types of folders described below.
Folder Type
Description
“system” Folder
This is one of the ClassPad’s reserved folders, which is provided by
default. It is used for storage of system variables, which are pre-
defined variables used by ClassPad applications and other system
operations.
Some examples of system variables are “list1” through “list6”, View
Window parameters “xmin” and “xmax”, etc. A system variable can be
accessed by any application simply by specifying the applicable
variable name.
“library” Folder
“main” Folder
User Folder
Also a ClassPad reserved folder, the “library” folder can be used for
storing user-created variables. Variables stored in the “library” folder
can be accessed without specifying a path, regardless of the current
folder setting (see next page).
The “main” folder is also a ClassPad reserved folder, and acts as the
default current folder. While the “main” folder is the current folder, all
variables created by ClassPad application operations are stored here
when you do not specify a path for variable storage.
This is a folder created and named by you. You can make a user
folder the current folder, move variables to a user folder, etc. You can
also delete and rename a user folder as required. You can have up to
87 user folders in ClassPad memory at one time.
Tip
• You cannot put a folder inside of another folder.
• You can view the contents of a folder using the Variable Manager (page 1-8-1). Note, however,
that you cannot open the “system” folder for viewing.
• The “system” folder contents are listed within the
selected for “Form”.
page of the keyboard when “Sys” is
ꢄ
20060301
1-7-2
Variables and Folders
Current Folder
I
The current folder is the folder where the variables created by applications (excluding
eActivity) are stored and from which such variables can be accessed. The initial default
current folder is the “main” folder.
You can also select a user folder you created as the current folder. For more information
about how to do this, see “Specifying the Current Folder” on page 1-8-3.
Variable Types
ClassPad variables can be broadly grouped into three types: general variables, system
variables, and local variables.
Variable Type
Description
General Variables A general variable is one you create using any name you want.
Unless you specify otherwise when you are creating it, a general
variable is stored in the current folder. You can use the same name
for multiple variables, as long as each of them is stored in a different
folder. General variables can be deleted, renamed, etc.
System Variables System variables are pre-defined reserved variables used by
ClassPad applications and other system operations. They are stored
in the “system” folder. System variables can be accessed without
specifying the folder name, and can even be accessed from another
folder. Since system variable names are reserved words, they cannot
be renamed. Whether you are allowed to delete or change the
contents of a system variable depends on each variable.
• For the names of and detailed information about system variables,
see the “System Variable Table” on page ꢀ-7-1.
Local Variables
A local variable is a variable that is temporarily created by a defining
function, program, or other operation for a particular purpose. A local
variable is deleted automatically when execution of the program or
user-defined function that created it is complete. You can create a
local variable by including the “Local” command in a program. Any
variable specified as the argument of a program or a user-defined
function is automatically treated as a local variable.
20060301
1-7-3
Variables and Folders
Variable Data Types
I
ClassPad variables support a number of data types. The type of data assigned to a variable
is indicated by a data type name. Data type names are shown on the Variable Manager
variable list, and on the Select Data dialog box that appears when you are specifying a
variable in any ClassPad application. The following table lists all of the variable data type
names and explains the meaning of each.

• For more information, see “Saving Graph Editor Data to Graph
Memory” on page 3-3-14.
Geometry application data

Data other than that described above
* Protected variable types
Some data types are protected. A variable whose data type is protected cannot be
overwritten with another variable, which protects variable contents from being inadvertently
altered. Data types whose names are marked with an asterisk in the above table are
protected.
Tip
• Note that whether or not a data type is protected is determined by the system. You cannot
change the protection status of a data type.
• Even when a variable is a protected data type, you can rename, delete, or move it. To disable
these operations, you need to lock the variable. For more information, see “Locking a Variable or
Folder” on page 1-7-10.

Tip
• You can use the Variable Manager to view the contents of a folder you create. For more
information, see “1-8 Using the Variable Manager”.
• For information about commands you can use to perform folder operations, see “12-6 Program
Command Reference”.
Folder Name Rules
I
The following are the rules that apply to folder names.
• Folder names can be up to 8 bytes long.
• The following characters are allowed in a folder name.
Upper-case and lower-case unaccented characters (character codes 65 to 90, 97 to 122)
Upper-case and lower-case accented characters (character codes 257 to 416, 513 to 672)
Subscript characters (character codes 480 to 491, 496 to 512, 737 to 746, 752 to 766)
Numbers (character codes 48 to 57)
Underscore (character code 95)
• Folder names are case-sensitive.
For example, each of the following is treated as a different folder name: abc, Abc, aBc,
ABC.
• A reserved word (system variable names, built-in function names, command names, etc.)
cannot be used as a folder name.
• A number, subscript characters or the underscore (_) cannot be used as the first character
of a folder name.
Creating and Using Variables
This section explains how to create a new variable (general variable), and provides a simple
sample calculation that illustrates how to use a variable.
Variable Name Rules
I
The rules for naming variables are identical to those that cover folder names. For more
information, see “Folder Name Rules” above.
20060301

Variables and Folders
Single-character Variable Precautions
I
Your ClassPad supports the use of single-character variables, which are variables whose
names consist of a single character like “ ” or “ ”. Some ClassPad keys (7, 8, '
a
x
keypad keys, math (mth) soft keyboard
,
,
,
keys,
key set keys, etc.) are
7 8 9 :
5
dedicated single-character variable name input keys. You cannot use such a key to input a
variable name that has more than one character.
For example, pressing the keypad keys 7and 8in succession is interpreted by the
ClassPad as the multiplication expression “x y”, and not as the characters “xy”. In order to
s
input a variable name made up of two or more characters, use the alphabet (abc) keyboard.
For more information, see “Using Single-character Variables” on page 1-6-12.
Creating a New Variable
I
The most common way to create a new variable is assigning a value or expression to the
applicable variable name. Use the variable assignment key ( ) to assign data to a variable.
6
Assign key
This key is included on the math
(mth) and 2D soft keyboards.
The following is an example of assignment to a variable while “main” is specified as the
current folder.
Example: To create a new variable named “eq1” and assign the expression 2x + 1 to it
The following assumes that there are no variables named “eq1” or “x” currently in
the “main” folder.
ClassPad Operation
S
(1) On the application menu, tap ꢉto start the Main application.
(2) Press .to display the soft keyboard, and then perform the following key operation.
ꢂA7ꢎ@6ꢃCO@U
• This creates a variable named “eq1” in the current folder (the “main” folder in this
example), and assigns the expression 2x + 1 to it.
20060301
1-7-7
Variables and Folders
Tip
• As shown in the above example, assigning something to a variable with a name that does not
yet exist in the current folder causes a new variable with that name to be created. If a variable
with the specified name already exists in the current folder, the contents of the existing variable
are replaced with the newly assigned data, unless the existing variable is protected. For more
information about protected variables, see “Protected variable types” on page 1-7-3.
• To store the newly created variable in a folder other than the current folder, specify the variable
name as follows: <folder name>\<variable name>.
• You can use the Variable Manager to view the contents of a variable you create. For more
information, see “1-8 Using the Variable Manager”.
Variable Usage Example
I
The following example uses the variable we created in the example under “Creating a New
Variable” on page 1-7-6.
Example: To copy the variable “eq1” and then paste it into the following two equations:
eq1 + x – 2 and eq1
2
s
ClassPad Operation
S
(1) First, check the current contents of variable “eq1”.
ꢃCO@U
(2) Copy the variable by dragging the stylus across “eq1” and then tapping
[Copy].
, or tap [Edit]
&
• Copy and paste comes in handy when you need to input the same variable into
multiple expressions. You can also drag “eq1” to another line.
(3) Perform the key operation below to input and execute the first expression:
eq1 + x – 2.
(or [Edit] [Paste])
'
ꢂꢎ7ꢏAU
(4) Perform the key operation below to replace the current contents of “eq1” with the list
{1, 2, 3}.

Variables and Folders
“library” Folder Variables
I
Variables in the “library” folder can be accessed without specifying a path name, regardless
of the current folder.
Example: To create and access two variables, one located in the “library” folder and one
located in another folder
ClassPad Operation
S
(1) With “main” specified as the current folder (the default), perform the following operation
to create a variable named “eq1” and assign the indicated list data to it.
{1, 2, 3}
eq1
U
2
(2) Keeping “main” specified as the current folder, perform the following operation to create
a variable named “eq2” in the “library” folder, and assign the indicated list data to it.
{4, 5, 6}
library \ eq2
2
U
Specifies the “library” folder.
(3) Check the contents of the two variables.
eq1
U
eq2
U
Since variable “eq2” is stored in the
“library” folder, you do not need to
indicate a path to access it.
(4) Change the current folder specification to “Test”.
• Use the Basic Format dialog box (page 1-9-4) or the Variable Manager (page 1-8-1)
to change the current folder specification.
(5) Perform the following operations to view the contents of variables “eq1” and “eq2”.
eq1
U
Since this key operation does not access the
“main” folder, the variable name (“eq1”) is
displayed without showing the variable contents.
main\eq1
U
Specifying the path to the “main” folder
where “eq1” is located displays the
contents of the variable.
20060301
1-7-9
Variables and Folders
eq2
U
Since variable “eq2” is stored in the
“library” folder, you do not need to
indicate a path to access it.
Tip
• Specifying a variable name that exists in both the current folder and the “library” folder causes
the variable in the current folder to be accessed. For details about the variable access priority
sequence and how to access variables in particular folders, see “Rules Governing Variable
Access” on page 1-7-11.
• You can use the Variable Manager (page 1-8-1) to move existing variables from the “main” folder
or a user folder to the “library” folder, or from the “library” folder to other folders.
Using Stat Editor to Create a LIST Variable
I
Stat Editor makes creation of LIST variables (variables that contain list data) quick and easy.
This capability really comes in handy when you need to perform a calculation (statistical
calculations, etc.) that involves a large number of LIST variables.
Stat Editor appears as the initial screen when you start up the Statistics application. You can
also access the Stat Editor window from the Main, Graph & Table, and eActivity applications.
ꢀ
ꢁ
Input a variable name like “list_t” into the title cell at the top of the list on the Stat Editor
ꢀ
ꢁ
window ( ), and then input values into the list ( ). This creates a LIST variable with the
ꢁ
name list_t that is assigned the contents of the list of data ( ). The above example creates a
LIST variable named “list_t” and assigns it the list data “{12, 24, 36}”.
Tip
• For details about using Stat Editor, see “7-2 Using Stat Editor”.

Assigning Values and Other Data to a System Variable
As its name suggests, a system variable is a variable that is created and used by the system
(page 1-7-5). Some system variables allow you to assign values and other data to them,
while some system variables do not. For more information about which variables allow you to
control their contents, see the “System Variable Table” on page -7-1.
A
Locking a Variable or Folder
Locking a variable or folder protects against inadvertently deleting it or changing its contents.
You can unlock a locked variable or folder to re-enable deletion and data assignment.
• Locking a variable disables the following operations on it: delete, overwrite, rename, and
move (to another folder).
• Locking a folder makes it impossible to delete or rename the folder.
Tip
• In terms of ClassPad variables, “lock” is completely different from “protect”. For more information
about “protect”, see “Variable Data Types” on page 1-7-3.
You can lock and unlock a variable or folder using either the Variable Manager or commands.
To lock or unlock a variable or folder using the Variable Manager
S
In the Variable Manager, select the folder or variable you want to lock or unlock and then
tap [Edit] - [Lock] or [Edit] - [Unlock]. For more information, see “1-8 Using the Variable
Manager”.
To lock or unlock a variable or folder using commands
S
In the Main application or in a program, execute one of the commands described below.
Use this command syntax:
Lock <variable name>
To do this:
Lock a variable
Unlock a variable
Lock a folder
Unlock <variable name>
LockFolder <folder name>
UnlockFolder <folder name>
Unlock a folder
For information about commands, see “12-6 Program Command Reference”.

Variables and Folders
Rules Governing Variable Access
Normally, you access a variable by specifying its variable name. The rules in this section
apply when you need to reference a variable that is not located in the current folder or to
access a variable that has the same name as one or more variables located in other folders.
Variable Search Priority Sequence
I
Specifying a variable name to access a variable, searches variables in the following
sequence.
(1) Local Variables
(2) Current Folder Variables
(3) “library” Folder Variables
• Multiple variables with the same name can exist simultaneously as a local variable, as
a variable in the current folder, and as a variable in the “library” folder. In this case, the
ClassPad searches folders according to the sequence shown above and accesses the first
instance of the variable that it finds. If you want to access such a variable when it occurs
lower in the above priority sequence, you need to specify the folder name along with the
variable name as shown in “Specifying a Variable in a Particular Folder” below.
• If a variable you specify cannot be found, it is treated as an “undefined variable”.
• Note that the “system” folder is not included in the above variable search. When accessing
a variable in the system folder, you need to specify the variable name only, without
specifying the folder name.
Tip
• Local variables exist only as long as the program or user-defined function for which it was created
in being executed.
• When a variable search is required during a subroutine called by a program or user-defined
function, the local variable search range includes only the local variables of the subroutine
currently being executed.
• For information about programs and user-defined functions, see Chapter 12.
• Only local variables and current folder variables are searched in the case of an operation that
stores variable data or a command that performs an operation on a variable (like “DelVar”).
Normally, “library” folder variables are not searched. If you want to include “library” folders in the
search, you need to specify the “library” folder as the variable location as explained below.
Specifying a Variable in a Particular Folder
I
You can access a variable located inside the “main” folder, “library” folder, or a particular
user folder by specifying the folder name along with the variable name. Use the following
syntax when specifying a folder name:
<folder name>\<variable name>
Example: To specify variable “abc” located in the “main” folder
main\abc

Variable Manager Folder Operations
This section describes the various folder operations you can perform using the Variable
Manager.
Specifying the Current Folder
I
The “current folder” is the folder where the variables created by applications (excluding
eActivity) are stored and from which such variables can be accessed. The initial default
current folder is the “main” folder.
You can also select a folder you created yourself as the current folder.
ClassPad Operation
S\
(1) Start up the Variable Manager and display the folder list.
Current folder
(2) Tap the [Current] down arrow button. On the list that appears, select the folder that
you want to specify as the current folder.
(3) Tap [Close] to close the folder list.
Creating a New Folder
I
You can use the following procedure to create up to 87 folders, as you need them.
ClassPad Operation
S\
(1) Start up the Variable Manager, which causes the folder list to appear.
(2) On the folder list, tap [Edit] and then [Create Folder].
• This displays a dialog box for inputting a folder name.
(3) Enter the folder name, and then tap [OK].
• This creates the new folder and returns to the folder list.
Normally, a folder name can contain up to eight bytes. If your folder name includes 2-byte
characters, you may not be able to input eight characters for the folder name. For details
about folder names, see page 1-7-5.
•
Tip
• An error message appears and your folder is not created if there is already a folder with the same
name you input. Tap [OK] to close the error message dialog box, and then specify a different
name for the folder you are creating.
