Important

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:

mTurn the television or radio antenna until the interference stops.

mMove the computer to one side or the other of the television or radio.

mMove the computer farther away from the television or radio.

mPlug the computer into an outlet that is on a different circuit from the

television or radio. (That is, make certain the computer and the television or radio are on circuits controlled by different circuit breakers or fuses.)

If necessary, consult your Apple-authorized service provider or Apple. See the service and support information that came with your Apple product. Or, consult an experienced radio/television technician for additional suggestions. You may find helpful the following booklet, prepared by the Federal Communications Commission: Interference Handbook (stock number 004-000-00493-1). This booklet is available from the U.S. Government Printing Office, Washington, DC 20402.

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. S

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 Ministère des Communications du Canada.

Preface

How to Use This Book

This book has several parts.

nChapter 1 explains how to set up your computer and learn how to use it.

nChapters 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.

nChapters 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.

nAt the back of the book you’ll find a troubleshooting section and an index.

Certain kinds of information are not included in this book.

nInformation 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.

nInformation about application programs. Your best source of information about a particular program is the set of books and disks that came with that program.

nTechnical 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.

PowerBook Duo

In this chapter

nSetting up your computer

nLearning how to use your computer

nTurning the computer on and off

nImportant care and safety instructions

nBeing comfortable while you work

nNew 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.

nNew 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.”

nExperienced PowerBook users: Skim this chapter for information that applies to your computer.

SImportant: 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

1

Setting up 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.

sWarning: 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. s

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.

sWarning: 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

2.Plug the power adapter cable into the power adapter port on the back panel of the computer.

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	Position the display at a comfortable viewing angle. You can
	adjust the angle of the display at any time.

n Slide the latch to the right and lift up the display.

Chapter 1: Setting Up Your PowerBook Duo 3

Step 3: Turn on the computer	When you see the Macintosh desktop on your screen, the
	computer is ready to use.

nTurn 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.

4 Chapter 1: Setting Up Your PowerBook Duo

Trouble?

nThe 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

nNothing happened when you pressed the Power On key.

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

nIf you have never used a Macintosh computer before, continue with the next section, “Learning the Basics.”

nIf 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.

nIf 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

The PowerBook comes with a tour and a tutorial to help you start using your computer as quickly as possible.

nThe Macintosh Basics tour teaches the most basic skills you need to master before you can use your computer.

nThe 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 Basics tour first.

Before you begin

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.”

vDifferent 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.”

3.Being careful not to roll the trackball, press the trackball button twice in quick succession.

Now your screen should look like the picture following step 4. If it doesn’t, try steps 2 and 3 again, paying special attention to the following:

nMake sure the tip of the arrow is touching the picture, not the words beneath it.

nBe sure to press the trackball button twice.

nTry 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.”

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.

5.Being careful not to roll the trackball, press the trackball button twice in quick succession.

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:

nMake sure the tip of the arrow is touching the picture, not the words beneath it.

nBe sure to press the trackball button twice.

nTry pressing twice more quickly and be careful not to roll the trackball while you press.

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.

Chapter 1: Setting Up Your PowerBook Duo 11

Turning the PowerBook on and off

nIf the computer is in sleep, wake it by pressing any key on the keyboard (except Caps Lock), and then choose Shut Down.

nIf 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.
