This equipment has been tested and found to comply with the limits for a Class B digital
device in accordance with the specifications in Part 15 of FCC rules. See instructions if
interference to radio or television reception is suspected.
Radio and television interference
The equipment described in this manual generates, uses, and can radiate radiofrequency energy. If it is not installed and used properly—that is, in strict accordance
with Apple’s instructions—it may cause interference with radio and television reception.
This equipment has been tested and found to comply with the limits for a Class B digital
device in accordance with the specifications in Part 15 of FCC rules. These specifications
are designed to provide reasonable protection against such interference in a residential
installation. However, there is no guarantee that interference will not occur in a
particular installation.
You can determine whether your computer system is causing interference by turning it
off. If the interference stops, it was probably caused by the computer or one of the
peripheral devices.
If your computer system does cause interference to radio or television reception, try to
correct the interference by using one or more of the following measures:
m Turn the television or radio antenna until the interference stops.
m Move the computer to one side or the other of the television or radio.
m Move the computer farther away from the television or radio.
S Important: Changes or modifications to this product not authorized by Apple
Computer, Inc., could void the FCC Certification and negate your authority to
operate the product.
This product was tested for FCC compliance under conditions that included the use
of shielded cables and connectors between system components. It is important that
you use shielded cables and connectors to reduce the possibility of causing
interference to radios, television sets, and other electronic devices. For Apple
peripheral devices, you can obtain the proper shielded cables from your Appleauthorized dealer. For non-Apple peripheral devices, contact the manufacturer or
dealer for assistance.
DOC Class B Compliance This digital apparatus does not exceed the Class B limits for
radio noise emissions from digital apparatus set out in the radio interference regulations
of the Canadian Department of Communications.
Observation des normes—Classe B Le présent appareil numérique n’émet pas de
bruits radioélectriques dépassant les limites applicables aux appareils numériques de la
Classe B prescrites dans les règlements sur le brouillage radioélectrique édictés par le

Preface
How to Use This Book
This book has several parts.
Certain kinds of information are not included in this book.
n Information about modems. If your computer has a built-in
modem, or if you purchase one later, you receive a separate
modem manual with instructions for its use.
n Chapter 1 explains how to set up your computer and learn
how to use it.
n Chapters 2–4 are a tutorial designed for people who have not
used a Macintosh computer before. If you are new to the
Macintosh, you should read this section of the book before
you start your own work.
n Chapters 5–14 contain reference information that will help
you as you become more proficient with your computer.
You can turn to these chapters for information about a
particular topic.
Most of the equipment designed specifically for use with your
PowerBook Duo—the Duo Dock, the Duo Floppy Adapter,
the Duo MiniDock, the external floppy disk drive, the external
battery recharger—is documented in these reference chapters.
n At the back of the book you’ll find a troubleshooting section
and an index.
n Information about application programs. Your best source of
information about a particular program is the set of books and
disks that came with that program.
n Technical specifications for your PowerBook Duo model.
These are on a separate sheet in the box with your computer.
(The illustrations contained in this book are of several PowerBook
Duo models, so the pictures may not exactly match your
PowerBook.)
Turn to Chapter 1 to set up your new PowerBook Duo computer.
Welcome to PowerBook Duo.

Chapter 1
Setting Up Your
P owerBook Duo
In this chapter
n Setting up your computer
n Learning how to use your computer
n Turning the computer on and off
n Important care and safety instructions
n Being comfortable while you work
n New Macintosh users: If you have never used a Macintosh
computer before, read this entire chapter. It explains how to
set up your computer, learn to use it, and turn it on and off.
n New PowerBook users:If you have used other Macintosh
computers but are new to the PowerBook, follow the setup
instructions that begin on the next page and then go to the
section “Turning the PowerBook On and Off.”
n Experienced PowerBook users:Skim this chapter for
information that applies to your computer.
S Important: No matter what your level of experience, please
read the safety information in this chapter before beginning
your own work. This information can help protect you and
your computer from possible harm.
S

Setting up the computer
2. Plug the power adapter cable into the power adapter
port on the back panel of the computer.
Step 1: Plug in the power adapter
Plugging in the power adapter recharges the computer’s battery
while you work. You should plug it in now in case the battery has
drained during shipping and storage.
s Warning: Use only the power adapter that came with your
PowerBook computer. Adapters for other electronic devices
(including other portable computers) may look similar, but
they may damage your computer.
Your computer’s power adapter comes with a detachable power
cord.
1. Plug one end of the power cord into the power adapter,
and the other end into a three-hole grounded outlet or
power strip.
s Warning: Your PowerBook is equipped with a three-wire
grounding plug—a plug that has a third (grounding) pin. This
plug is a safety feature, and is meant to fit only a grounded AC
outlet. If you are unable to insert the plug into an outlet,
contact a licensed electrician to replace the outlet with a
properly grounded outlet.
s
s
You can keep extra cable out of the way by winding it around
the clips that open out from the power adapter.
Depending on where you purchased your computer, you may also
have received a wall mount plug. You can use this plug instead of
the power cord to plug the power adapter directly into an
electrical outlet.
2 Chapter 1: Setting Up Your PowerBook Duo
Step 2: Open the display
n Slide the latch to the right and lift up the display.
Position the display at a comfortable viewing angle. You can
adjust the angle of the display at any time.

Chapter 1: Setting Up Your PowerBook Duo 3
Step 3: Turn on the computer
n Tu rn on the computer by pressing the Power On key
above the keyboard.
Power On key
You hear a tone when you turn on the computer. It takes the
computer a moment to start up.
When you see the Macintosh desktop on your screen, the
computer is ready to use.
4 Chapter 1: Setting Up Your PowerBook Duo
Trouble?
n Nothing happened when you pressed the Power On key.
n The computer made a sound, but you can’t see anything on
the screen.
Adjust the brightness and contrast controls until an image
appears and the screen is easy to read. (Some models do not
have control buttons to manually adjust the contrast. In these
cases, just the brightness controls appear.)
Contrast
Brightness
Make sure the power adapter is firmly connected to both
the computer and a power source. If the power adapter is
plugged into a power strip, make sure the power strip is
plugged in and turned on. Then try pressing the Power On
key again.
If you still get no results, press the power button on the back
of the computer.
Power button
If neither the Power On key nor the power button turns the
computer on, the service and support information in the
reference section of this book explains how to get help.
Chapter 1: Setting Up Your PowerBook Duo 5
n You see a blinking question mark icon on the screen.
This icon means that you need to install system software on
the computer’s hard disk. System software includes the
programs the computer uses to start itself up. You received a
set of system software disks in the box with your computer.
For instructions, see the chapter on installing system software
in the reference section of this book.
What to do next
n If you have never used a Macintosh computer before,
continue with the next section, “Learning the Basics.”
n If you have never used a PowerBook computer before,
continue with the section “Turning the PowerBook On and
Off.” This section contains information about power states
that can help you use your computer efficiently.
n If you are an experienced PowerBook user, you are ready to
start your own work.
6 Chapter 1: Setting Up Your PowerBook Duo
Learning the basics
Before you begin
The PowerBook comes with a tour and a tutorial to help you start
using your computer as quickly as possible.
n The Macintosh Basics tour teaches the most basic skills you
need to master before you can use your computer.
n The tutorial section of this book (Chapters 2–4) reviews the
basic skills taught in the tour, and teaches a few additional
skills you’ll find helpful as you become more proficient.
Take the Macintosh Basicstour first.
Make sure your computer is turned on. If the screen is dark, try
the following steps in order until you see the Macintosh desktop
on your screen.
1. Adjust the screen brightness and contrast controls.
If you see the Macintosh desktop, skip to “Starting the Tour.”
2. Press any key on the keyboard (except Caps Lock).
Pressing a key wakes the computer if it was in sleep (a powerconserving state described later in this chapter). If you see the
Macintosh desktop, skip to “Starting the Tour.”
3. Press the Power On key above the keyboard.
Pressing the Power On key turns the computer on if it was off.
Continue with “Starting the Tour.”
Chapter 1: Setting Up Your PowerBook Duo 7
Starting the tour
1. Roll the trackball to move the arrow pointer around on
the screen.
Place the index finger of your dominant hand on the trackball
and the thumb of the same hand on the lower trackball
button. Don’t press either button yet.
Watch the arrow on the screen while you roll the trackball,
and notice that the arrow moves in the same direction that
you roll the trackball.
You may need to roll the trackball around for a few seconds to
“break in” the mechanism so it works smoothly.
8 Chapter 1: Setting Up Your PowerBook Duo
2. Roll the trackball to move the arrow over the picture
labeled “Macintosh HD.”
3. Being careful not to roll the trackball, press the
trackball button twice in quick succession.
v Different name? The picture on your screen may be labeled
“PowerBook HD” instead of “Macintosh HD.” The different
name is not important; you can still follow directions in this
manual by replacing references to “Macintosh HD” with
“PowerBook HD.” v
Make sure the tip of the arrow is over the picture, not over
the words “Macintosh HD.”
Now your screen should look like the picture following
step4. If it doesn’t, try steps 2 and 3 again, paying special
attention to the following:
n Make sure the tip of the arrow is touching the picture, not
the words beneath it.
n Be sure to press the trackball button twice.
n Try pressing twice more quickly and be careful not to roll
the trackball while you press.
continues .
Chapter 1: Setting Up Your PowerBook Duo 9
4. Roll the trackball to move the arrow over the picture of
the folder labeled “Macintosh Basics.”
5. Being careful not to roll the trackball, press the
trackball button twice in quick succession.
Make sure the tip of the arrow is over the picture, not over
the words “Macintosh Basics.”
The items in the illustration below may not exactly match
those on your screen. The only item you need right now is the
Macintosh Basics folder.
Now your screen should look like the following illustration:
6. Roll the trackball to move the arrow over the picture of
the man labeled “Macintosh Basics.”
Make sure the tip of the arrow is over the picture of the man,
not over the words “Macintosh Basics.”
10 Chapter 1: Setting Up Your PowerBook Duo
7. Press the trackball button twice in quick succession.
Now your screen should look like the following picture:
If you don’t see this screen, try again, paying special attention
to the following:
n Make sure the tip of the arrow is touching the picture, not
the words beneath it.
8. Follow the instructions on the screen and work through
the tour.
When you finish the tour, continue with “Turning the PowerBook
On and Off” and read the rest of this chapter for information that
can help you use your computer safely and efficiently. Then turn
to Chapter 2 and begin the tutorial.
n Be sure to press the trackball button twice.
n Try pressing twice more quickly and be careful not to roll
the trackball while you press.

To turn the PowerBook off
Your PowerBook can be in one of three power states: off, sleep, or
on.
Off
When the PowerBook is off, the computer is not using any power
or doing any work. The terms shut down and offboth refer to this
state.
Turn the computer off to
n insert it into a PowerBook Duo Dock or Duo Dock II
n connect it to a desktop Macintosh as a SCSI disk
n conserve power when you won’t be using it for several hours
n If the computer is on, choose the Shut Down command from
the Special menu. (The Macintosh Basics tour teaches how to
choose a menu command.)
n If the computer is in sleep, wake it by pressing any key on the
keyboard (except Caps Lock), and then choose Shut Down.
n If a problem with the computer prevents you from choosing
Shut Down, press the power button on the back panel of the
computer. This turns off the power; it is not a graceful exit,
because you will lose any work you did not save. Use the
power button only in an emergency.

Automatic sleep
If you don’t use the computer for several minutes, it goes to sleep
automatically. This conserves battery power. You will notice that if
you spend several minutes reading without using the computer,
or if you take a break, the screen may be dark when you’re ready
to resume working.
To wake the computer, press any key on the keyboard (except
Caps Lock). The desktop reappears looking just the way it did
before the computer went to sleep.
