Radio and television interference

The equipment described in this manual generates, uses, and can radiate radio-frequency 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. m Plug 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 an 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 the following booklet helpful: Handbook (stock number 004-000-00493-1). This booklet, prepared by the Federal Communications Commission, is available from the U.S. Government Printing Office, Washington, DC 20402.

IMPORTANT

Follow the instructions in this

chapter to set up your computer

and learn the basics.

Getting Started

The illustration on the facing page shows all the equipment you will need to set up your computer and begin using it. Place your equipment on a sturdy, flat surface near a grounded wall outlet. Before following the setup instructions in this chapter, you may want to read “Arranging Your Office” in Appendix A (in the section on health-related information) for tips on adjusting your work furniture so that you’re comfortable when using the computer.

Plugging in the computer

Before you plug your Macintosh into a wall socket (and before you connect anything else to your Macintosh), carefully read all the setup instructions in this chapter. Then, begin by plugging in the computer according to the instructions that follow. The plug grounds the computer and protects it from electrical damage while you are setting up.

When you are ready to begin, follow these steps:

Power cord plug Power cord socket Standby power button

1Plug the socket end of the computer’s power cord into the recessed power cord socket

≤

(marked with the symbol

2Plug the other end of the power cord into a three-hole grounded outlet or power strip.

) on the back of the computer.

Choose a power outlet to which you have easy access.

WARNING

This equipment is intended to be electrically grounded.Your Macintosh is equipped with a three-wire grounding plug—a plug that has a third (grounding) pin. This plug will fit only a grounded AC outlet. This is a safety feature. If you are unable to insert the plug into the outlet, contact a licensed electrician to replace the outlet with a properly grounded outlet. Do not defeat the purpose of the grounding plug!

IMPORTANT

Be sure that at least one end of the power cord is within easy

reach so that you can unplug the computer when you need to.

If the computer starts up: If you hear a tone, the computer has started up and you need to turn it off before proceeding. Press the power button (also called the standby power button) located on the back of the computer to turn the computer off.

Chapter 1

Installing an expansion card

If you purchased any expansion cards separately from your Macintosh, install them now. (For instructions, see Appendix B, “Installing an Expansion Card,” as well as the documentation that came with the cards.) If you don’t have an expansion card, go on to the next section, “Connecting a Monitor.”

Connecting a monitor

You can connect many types of monitors to your Macintosh. To connect a monitor from a manufacturer other than Apple, refer to the instructions that came with the monitor.

Connecting the monitor power cord

Monitors have two cords to connect—a power cord and a monitor cable.

To connect the monitor power cord, follow these steps:

1Place the monitor where you will be using it.

You may place it on top of your computer. Keep these considerations in mind: m Allow a few inches for air circulation around the sides of the computer

and monitor.

m Make sure that the top of the screen is slightly below eye level when you’re

sitting at the keyboard.

m Position the monitor to minimize glare and reflections on the screen from

overhead lights and windows.

m Consult “Arranging Your Office” in Appendix A for suggestions on

locating your computer equipment.

2Connect the monitor power cord to the monitor.

Tips for using Macintosh Guide

Here are a few tips for using Macintosh Guide effectively: m Macintosh Guide is available only when you are in the Finder—the

desktop area where you can see the icons of disks, folders, and files. (Other programs may also have help available in the Guide menu, however.) If you don’t see Macintosh Guide in the Guide menu, pull down the Application menu (to the right of the Guide menu) and choose Finder.

m Follow the steps when you’re instructed to; don’t skip ahead or read

ahead. That way the computer can check to make sure you’ve done a step correctly.

m Unlike most windows, the Macintosh Guide window stays in front of

other windows on the screen so that your instructions are never covered. If you need to move the Guide window out of the way, drag it by the title bar at the top of the window.

You can also move the window out of the way by clicking the zoom box. Click the box once to shrink the window; click it a second time to expand the window to its original size.

m If you need more information about an instruction or a term, click the

button labeled “Huh?” to get further explanation. (The “Huh?” button is dimmed when no additional information is available.)

m If you want to return to the main Macintosh Guide window, click the

Topics button in the lower-left corner of the Guide window.

You can take advantage of your computer’s stereo sound output by attaching external powered (amplified) speakers.

1 Assemble the speakers and the cable you need.

You need a cable with stereo miniplugs at each end to connect one or both speakers to the computer. (Some speakers require a dual-plug adapter. Others, like those shown here, accept a single stereo miniplug and are joined by standard speaker wires.)

The following illustration shows the equipment configuration and the connections for a computer sound system.

2 Turn off the Macintosh.

3Plug a stereo miniplug into the sound output port on the Macintosh.

4Plug a stereo miniplug into the Audio In port on one of the speakers.

If the speakers take a dual-plug cable, connect both plugs to the speakers’ Audio In ports.

Chapter 3

5Connect the speakers together with speaker wires, if necessary.

6 Turn on the computer.

You hear the computer’s sound through the external speakers.

Note: To control the volume of your external speakers, use the volume buttons on the front of the computer. If you are playing an audio compact disc (CD), you may also need to adjust the volume control in the program you’ re using to play CDs. For more information on sound and playing audio CDs, see the “Sound” topic of Macintosh Guide, available in the Guide (h) menu.

Connecting Additional Equipment

Expanding memory

The random-access memory (RAM) in your computer can be expanded. Installing additional RAM adds more memory chips to your computer and expands its capabilities. The Technical Information booklet that came with your computer describes how much additional memory can be installed in your Macintosh.

WARNING

only an Apple-certified technician install additional RAM. Consult the service and support information that came with your computer for instructions on how to contact an Apple-authorized service provider or Apple for service. If you attempt to install additional RAM yourself, any damage you may cause to your equipment will not be covered by the limited warranty on your computer. See an Apple-authorized dealer or service provider for information about this or any other warranty question.

Installing internal drives

Your Macintosh can hold up to three internal storage devices, including a floppy disk drive, a CD-ROM (compact disc read-only memory) drive, and a hard disk drive (several capacities are available). These drives may already be installed. If you want to add or replace an internal drive, see your Appleauthorized dealer.

To avoid damage to your computer, Apple recommends that

with application programs and protect

the information on your disks.

Using Programs and Backing Up Disks

Your computer came installed with several ready-to-use application programs. You can open these programs by clicking their buttons in the Launcher.

The Apple Extras folder on your hard disk (or the contains other programs (some of which must be installed before they will work), including the following:

m AppleScript. You need AppleScript on your hard disk in order to use

Macintosh Guide. With AppleScript you can also automate tasks in the Finder and other scriptable programs (programs that support AppleScript). Instructions for using AppleScript are included in the AppleScript folder.

m QuickDraw GX gives your computer more powerful printing and font

capabilities. You’ll want to install QuickDraw GX if you purchased another program that requires it. If your computer has at least 8 megabytes of random-access memory (RAM), you can install QuickDraw GX by opening the QuickDraw GX folder and double-clicking the Installer icon.

m PowerTalk provides an open collaboration environment with a universal

mailbox and other electronic mail services. You’ll want to install PowerTalk if you purchased another program that requires it. If your computer has at least 8 megabytes of RAM, you can install PowerTalk by opening the PowerTalk folder and double-clicking the Installer icon.

Macintosh Performa CD)

m Apple Video Player lets you watch video or TV on your computer. With

Apple Video Player and a video input card, you can watch video on your computer. With Apple Video Player, a video input card, and a TV tuner card, you can watch video and TV. For instruction on using Apple Video Player, open Apple Video Player and then choose Apple Video Player Guide from the Guide (h) menu.

Installing application programs

Insert the floppy disk, metal end first, into the floppy disk drive of your computer.

You’ll probably want to buy and install additional application programs. See the manuals you receive with your programs for instructions on installing and using them.

In most cases, you’ll install an application program on your internal hard disk from floppy disks that contain the program. The following illustration shows how to insert a floppy disk in your computer’s floppy disk drive.

For instructions on how to eject floppy disks, see the “Disks” topic of Macintosh Guide, available in the Guide (h) menu.

Chapter 4

To use your programs most effectively, follow these guidelines: m Put only one copy of each program on your hard disk. Having more than

one copy can cause errors.

m Whenever you copy a program disk to your hard disk, be careful not to

copy a System Folder. Always check to see what you’ve copied, and drag any extra System Folders to the Trash.

m If you have problems using a program, read the manuals you received with

the program.

m If a program malfunctions consistently, try installing a fresh copy. If that

doesn’t help, find out from the software manufacturer whether your version of the program is compatible with the system software you’re using.

For instructions on how to put a program into the Launcher, see the “Launcher” index topic of Macintosh Guide, available in the Guide (h) menu.

Working with several programs at a time

You can open as many application programs and desk accessories as your computer’s memory allows.

All open programs are listed in the Application menu at the right end of the menu bar. The name of the active program (the one you’re using right now) has a checkmark next to it, and its icon appears in the menu bar.

The Finder icon

Commands to hide or display open windows

A checkmark

indicates the active

program.

Open programs

Finding out which programs are open

If you have several programs and windows open, you can find out which program is active and which other programs are open by pulling down the Application menu.

Switching programs

You can switch to another open program or desk accessory by choosing its name from the Application menu.

If a program’s icon is dimmed in the menu, that means its windows are hidden. Choosing the program from the Application menu displays its windows.

You can also switch to another program by clicking in a window that belongs to an open program, or by double-clicking a program icon (or the icon of a document that was created with the program).

Using Programs and Backing Up Disks

Hiding and showing windows on the desktop

You can hide all windows except those of the active program by choosing Hide Others from the Application menu.

The other programs remain open even though their windows are hidden. When you switch to another program, its windows become visible again.

If you want to see all the open windows, choose Show All from the Application menu.

Protecting the information on a disk

Your computer’s hard disk comes with a lot of valuable information already stored on it, including system software and some application programs. If you had a valuable document like a birth certificate, you’d probably make an extra copy of it for safekeeping. Similarly, you should make a copy of the information on your hard disk for safekeeping. (The extra copy is called a backup, and the process of making the copy is called backing up.)

Once you have a backup, you’re protected from accidentally losing the information on your hard disk. In the unlikely event that something happens to your hard disk, you can easily get the information back.

Backing up your files

You can back up the work you store on a hard disk by copying individual files to another disk in the usual way (dragging the files’ icons to the icon of the other disk). You can back up the contents of an entire floppy disk by dragging its icon to another floppy disk or hard disk icon.

If your computer has a CD-ROM drive

If your computer has a CD-ROM drive, you also received the Macintosh Performa CD, which contains a backup copy of all the software that came

with your computer. You should make backup copies of the documents you create. If you alter the contents of your System Folder, you may also want to use Apple Backup and Apple Restore—application programs that came with your computer—to preserve the contents of your hard disk. (See the following sections for instructions on using Apple Backup and Apple Restore.)

Chapter 4

If your computer does not have a CD-ROM drive

If your computer does not have a CD-ROM drive, use Apple Backup to copy the entire contents of your Macintosh hard disk to floppy disks. Keeping this backup copy up-to-date will protect you in case information on your hard disk is accidentally lost or damaged. You should update your backup copy at least once a month, and in between full backups you should store copies of important documents on floppy disks.

If something happens to the information on your hard disk, you can use the backup copy you made to put the information back on your hard disk. To do this, you use Apple Restore. (See the following sections for instructions on using Apple Backup and Apple Restore.)

It’s a good idea to keep two sets of backup copies, and to alternate between them (using one set one month, and the other the next) when updating your backup copy. This protects you from losing files in the unlikely event that a problem damages the files on both your internal hard disk and your backup set of floppy disks.

You can also purchase a backup program with additional features that make copying faster. (For example, some programs have a feature that lets you copy only the new and changed information on your hard disk.)

Using Apple Backup for the first time

If you have a Macintosh Performa CD, you don’t need to use Apple Backup, because the CD contains all the software that came with your computer. However, if you don’t have the CD as backup, use Apple Backup to copy the software to floppy disks, as backup.

5 Click the appropriate button, as follows:

m If you have enough disks to copy everything, then click the Copy All

Files button.

m If you have only enough disks to copy the System information, then click

the Copy System Folder button. As soon as you buy more disks, follow the instructions in this chapter to back up everything.

m If you don’t have enough disks for either choice, click the Quit button.

6 Insert a high-density floppy disk into the disk drive.

A message tells you when it’s time to insert another floppy disk.

7 Lock each disk as you remove it from the computer. Label the disks to indicate the order

in which you create them (for example:

Backup 1,Backup 2

, and so on).

To lock a disk, turn it label-side down and use a pen or your fingernail to slide the tab in the lower-right corner of the disk so that the square hole is open. (The disk has two square holes, but only one of them has a moveable tab.)

8When a message appears telling you that you’ve finished, store the labeled and locked

floppy disks in a safe, cool place.

Using Apple Backup to update your backup copy

If you made a backup copy of your hard disk information on floppy disks using Apple Backup, you can keep your backup copy up-to-date by following the instructions here.

By the way: Another way to make sure you have up-to-date information is to use a new set of floppy disks to create your backup copy, preserving your original backup. If you are using a fresh set of floppy disks, follow the instructions in the previous section, “Using Apple Backup for the First Time.”

1Get the floppy disks that you used to make a previous backup copy.

Have some extra high-density disks on hand in case there is more information on your hard disk than there was the last time you made a copy.

2 Turn on your Macintosh, if it’s not already on.

3Click the Applications grouping button in the Launcher.

The buttons for application programs available in the Launcher are grouped under the Applications button.

6Make sure your floppy disks are high-density. Then click the Continue button.

A message appears, telling you how many disks you will need to copy all files on your hard disk, or to copy just the System Folder. It also tells you approximately how long it will take to make the copy.

Copy all files or just the System Folder? Because all the information on your hard disk is important, it’s recommended that you make a copy of all the files on the hard disk. But if you don’t have enough disks or time right now to make a copy of everything, you can choose to make a copy of just the System Folder.

If you want to be doubly protected, you can make a copy of all files and then start Apple Backup again and make an extra copy of the System Folder. That way, if something goes wrong with your System Folder, you can replace it quickly without having to copy everything back onto your hard disk.

7Click the button that corresponds to your choice.

Make sure you have enough time and disks to complete the copying. If you stop the copying before it’s done, you’ll have to start over from the beginning.

8Unlock your first backup floppy disk.

To unlock the disk, turn the disk label-side down and use a pen or your fingernail to slide the tab in the lower-right corner of the disk so that it covers the square hole. (The disk has two square holes, but only one of them has a moveable tab.)

9 Insert the disk into the floppy disk drive.

If you did not unlock the disk correctly, it is ejected and a message appears. Unlock the disk, making sure that the tab snaps into place, and try again.

A message appears, telling you that the disk contains information.

10 Click the Continue button.

If there is a problem with the disk, a message appears. Otherwise, copying takes place automatically. A sound alerts you when it’s time to insert another disk.

11 When the disk is ejected, lock and label it.

To lock a disk, turn it label-side down and use a pen or your fingernail to slide the tab in the lower-right corner of the disk so that the square hole is open.

Apple Backup lets you know when you’ve finished.

13 Store the disks in a safe, cool place.

Using Programs and Backing Up Disks

Restoring the information on your hard disk

If information on your hard disk becomes damaged or lost, you can restore it if you have a backup copy of the information. If your computer has a CD-ROM drive, the Macintosh Performa CD contains copies of all the system software and application programs that came with your computer. See the

Macintosh Performa CD booklet for instructions on using the Macintosh Performa CD.

If you have used Apple Backup to copy the information on your hard disk to floppy disks, you can use the Apple Restore program to put that information back on your hard disk. You can also use Apple Backup and Apple Restore to replace only the System Folder (the folder that contains the software the Macintosh uses to operate). See the following section, “Using Apple Restore,” for instructions.

If your computer doesn’t have a CD-ROM drive and you have not used Apple Backup to back up the contents of your hard disk, call the customer support hotline. (The phone number for the hotline is in the service and support information that came with your computer.)

Using Apple Restore

If you made backup floppy disks with Apple Backup, follow these steps to restore your information:

If you are unable to access Macintosh Guide (for example, if your screen is “frozen”), refer to this chapter to see if you can resolve the problem.

Take your time

When you see an error message, you don’t have to take action immediately. The message stays on the screen until you click the OK button or turn off the Macintosh.

To help diagnose and correct the problem, gather as much information on the situation as you can before starting over.

m Make a note of exactly what you were doing when the problem occurred.

Write down the message on the screen and its ID number (if any). Also list the programs you were using and the names of any items you know have been added to the System Folder since the system software was installed. This information will help a service person diagnose the problem. (It is helpful to keep a printed copy of the items in your System Folder. For instructions on printing the contents of a folder, see the “Printing & Fonts” topic of Macintosh Guide, available in the Guide [h] menu.)

m Check the screen for any clues. Is a menu selected? What programs and

document icons are open? Note anything else that seems relevant.

m If you were typing text and were not able to save it before the problem

occurred, you can write down the parts of the text still visible on the screen so that some of your work will be easy to replace.

m Ask other Macintosh users about the problem you’re having; they may have

a solution for it.

If you need repair service, consult the service and support information that came with your computer for instructions on how to contact an Appleauthorized service provider or Apple for assistance.

Chapter 5

Start over

Often you can eliminate a problem simply by clearing the computer’s memory and starting over.

If you can, save any open documents before restarting the Macintosh. If your system is frozen and does not respond to anything you do, or if you have a “bomb” message on the screen, saving may not be possible. You can try pressing x-Option-Esc to quit the program in use when the problem occurred; if this works, you can then save the documents open in other programs before restarting.

To restart your Macintosh, try the following steps:

1If you can, choose Restart from the Special menu or from the dialog box that’s on the

screen.

Dialog boxes contain messages from the computer. If something goes wrong, a message may appear on the screen, asking you to restart the computer.

2If you can’t choose Restart, hold down the

and Control keys while you press the

This key combination restarts the computer. (Use this key combination only when you can’t choose Restart from the Special menu.)

3If nothing happens, turn off your computer with the standby power button, wait at least

10 seconds, and then turn it on again.

4If the standby power button doesn’t turn off the computer, unplug your Macintosh.

If you suspect that the problem is with other equipment, such as a printer or an external hard disk that’s attached to your computer, turn that equipment off for 10 seconds or longer, then turn it on again and restart the Macintosh.

Troubleshooting

Rebuild your desktop regularly

A process known as “rebuilding the desktop” helps your Macintosh keep track of data on your startup disks. Although you usually use the hard disk in your computer as a startup disk, you can also start up from any other disk that has system software installed. It’s a good idea to rebuild the desktop of your startup disks once a month or so.

To rebuild the desktop of a startup disk, follow these steps:

1Hold down the Option and xkeys while you start up your computer.

Do not release the keys until you see a message asking whether you want to rebuild the desktop.

2 Click OK.

Chapter 5

Solutions to common problems

The computer is turned on but the screen is dark.

One of the following is probably the cause: m You have a screen saver program that darkens the screen when the

computer has not been used for a certain period.

Press a key or move the mouse to turn off the screen saver.

m The monitor’s brightness control (¤) is not adjusted properly.

Check the monitor’s brightness control and turn it up if necessary.

m The Macintosh or the monitor is not getting power.

If you have a separate monitor, check that the monitor is plugged in and turned on, and that the monitor cable is firmly connected to both the computer and the monitor.

Check that the computer’s power cord is firmly connected to the computer and plugged into a grounded electrical outlet, and that the outlet has power.

If you have more than one monitor and only one is dark, check that it is set up correctly in the Monitors control panel. For information on using more than one monitor, see the “Monitors” topic of Macintosh Guide, available in the Guide (h) menu.

If you are displaying video from your computer on a television screen, it is normal for your computer monitor to be dark.

The computer’s clock keeps time inaccurately.

Your computer has a clock that runs continuously. When the computer is turned off, a battery keeps the clock running. If your clock begins to keep time inaccurately, have your Apple-authorized service provider replace the battery.

Troubleshooting

When you start up, a disk icon with a blinking question mark appears in the middle of the screen.

This icon indicates that your Macintosh cannot find the system software it needs to start up. One of the following is probably the cause:

m Your computer may be having a problem recognizing external equipment

that uses the Small Computer System Interface (SCSI).

Turn off all external SCSI equipment and disconnect the first SCSI device in the chain from your computer’s SCSI port. Then restart the computer. If the computer starts up after you disconnect your SCSI equipment, refer to the manuals that came with the equipment for information on the proper way to connect SCSI equipment and assign SCSI ID numbers.

If you have a printer connected to your computer’s SCSI port, make sure your printer is not supposed to be connected to the printer port instead. Check the manuals that came with your printer for information on how to connect it properly.

m System software is not installed on the startup hard disk, the system

software is damaged, or the hard disk is not working properly.

Chapter 5

Start up your computer using the

Utilities floppy disk or, if you have a builtin CD-ROM drive, using the Macintosh Performa CD. (For instructions on how to start up your computer from the CD-ROM disc, see “Starting Up From a CD-ROM Disc” in the section “Repairing a Damaged Disk” later in this chapter.) Then follow the rest of the instructions on repairing a disk to test your startup hard disk and repair any damage.

If repairing the disk doesn’t help, follow the instructions in “Installing or Reinstalling System Software” later in this chapter to reinstall system software on your startup hard disk.

When you try to start up from a floppy disk, a disk icon with an X appears in the middle of the screen and the floppy disk is ejected.

This icon indicates that the floppy disk you tried to start up from is not a startup disk.

Wa it a few seconds. The computer should start up from its internal hard disk. Make sure you insert floppy disks only after the computer has begun starting up.

A “sad Macintosh” icon appears and the computer won’t start up.

This icon indicates that your Macintosh cannot start up because of a problem with the system software or the computer hardware.

Eject any floppy disks by turning off the computer and then holding down the mouse button while you turn the computer on again. Try starting up with the Utilities floppy disk or, if you have a built-in CD-ROM drive, with the Macintosh Performa CD.(For instructions on how to start up your computer from the CD-ROM disc, see “Starting Up From a CD-ROM Disc” in the section “Repairing a Damaged Disk” later in this chapter.) If the “sad Macintosh” icon appears again, consult the service and support information that came with your computer for information on contacting an Appleauthorized service provider or Apple for assistance.

Troubleshooting

The hard disk icon does not appear on the desktop.

If you don’t see a hard disk icon on the desktop, try the following: m If the hard disk is internal, shut down your computer, wait at least 10

seconds, and then turn it on again.

m If the hard disk is external, make sure that it is turned on and that its cable

is connected firmly; then restart the Macintosh.

m Check the ID numbers of all SCSI equipment connected to your computer.

See the manuals that came with your SCSI equipment for information on setting SCSI ID numbers.

m If the hard disk is your startup disk, start your computer using the Utilities

floppy disk or, if you have a built-in CD-ROM drive, with the Macintosh Performa CD. (For instructions on how to start up your computer from the CD-ROM disc, see “Starting Up From a CD-ROM Disc” in the section “Repairing a Damaged Disk” later in this chapter.) Then follow the rest of the instructions on repairing a disk to test your startup hard disk and repair any damage.

If repairing the disk doesn’t help, follow the instructions in “Installing or Reinstalling System Software” later in this chapter to reinstall system software on your startup hard disk.

Icons do not appear correctly on your screen.

You need to rebuild the desktop—a process that helps your Macintosh keep track of files and folders on your hard disks. For instructions, see “Rebuild Your Desktop Regularly” in the section “When You Run Into Trouble” earlier in this chapter.

If icons do not appear correctly after you rebuild the desktop, restart your computer while pressing the Shift key to temporarily turn off system extensions. When you see the “Welcome to Macintosh—extensions off” message, release the Shift key and press the Option and x keys until you see a message asking if you want to rebuild the desktop.

Chapter 5

Your Macintosh can’t read a floppy disk.

If you see a message that a floppy disk is unreadable, try one of the following: m If the disk has never been used, you may simply need to initialize it. For

instructions, see the “Disks” topic of Macintosh Guide, available in the Guide (h) menu.

m The disk may be damaged. See “Repairing a Damaged Disk” later in this

chapter for information on testing and repairing disks.

m If the disk is a high-density disk previously used on another computer, the

disk may have been formatted incorrectly as an 800K disk rather than as a 14 40K (high-density) disk. If so, use the other computer to copy the disk’s contents onto a properly formatted disk.

If you are trying unsuccessfully to use a DOS floppy disk, consider the following:

m When formatting floppy disks on a DOS computer for use in a Macintosh,

users need to format standard double-sided disks as 720K disks and highdensity disks as 1440K disks. Because DOS computers allow standard double-sided disks to be formatted in 1440K format and high-density disks to be formatted in 720K format, it’s possible that your disk has been given a format that won’t work in a Macintosh. If you think your DOS floppy disk might have a format that doesn’t work in a Macintosh, use a DOS computer to copy the contents of your DOS floppy disk onto another DOS floppy disk that has been properly formatted for use in a Macintosh.

Troubleshooting

A dialog box with a bomb appears.

Your system has a software problem. m Write down what you were doing when the message appeared, the text of

the message, and the message number, if there is one.

m Restart your Macintosh. (See “Start Over” in the section “When You Run

Into Trouble” earlier in this chapter for instructions.) Most software problems are temporary, and restarting usually corrects the problem.

m Check the startup disk and application program you were using when the

dialog box appeared. Make sure that all programs, desk accessories, and system extensions you’re using are compatible with the system software. Reinstalling the system software may correct the problem.

m Sometimes incompatible system extensions or control panels can cause

system software problems. Restart while holding down the Shift key; this temporarily turns off all system extensions. If your computer works normally after you do this, use the Extensions Manager control panel to turn on extensions and control panels one at a time. Restart after you turn on each extension. This procedure should identify any incompatible extensions.

For information on using the Extensions Manager control panel to manage system extensions, see the “Setting Options” topic of Macintosh Guide, available in the Guide (h) menu.

m If the problem recurs, you may need to reinstall system software. See

“Installing or Reinstalling System Software” later in this chapter for instructions.

The pointer (8) doesn’t move when you move the mouse.

One of the following situations is probably the cause. m Your system has a software problem. Try one or more of the following:

Press x-Option-Esc to quit the application program in use when the problem occurred. If this works, you can save the documents open in other programs before restarting.

Restart your Macintosh. See “Start Over” in the section “When You Run Into Trouble” earlier in this chapter for instructions.

m Signals from the mouse are not reaching the computer, either because the

mouse needs cleaning or because there is something wrong with the mouse.

Clean the mouse according to the instructions in Appendix A of this book.

If you have another mouse or pointing device, try connecting and using it. (Turn off the computer before connecting it.) If the new device works, there is probably something wrong with the mouse you replaced.

If none of these procedures solves the problem, consult the service and support information that came with your computer for instructions on how to contact an Apple-authorized service provider or Apple for assistance.

Troubleshooting

Typing on the keyboard produces nothing on the screen.

One of the following is probably the cause: m Your system has a software problem.

Restart your Macintosh. For instructions, see “Start Over” in the section “When You Run Into Trouble” earlier in this chapter.

Check the startup disk and application program you were using when the problem occurred. Make sure that all programs, desk accessories, and system extensions you’re using are compatible with the system software.

If the problem recurs, you may need to reinstall system software. See “Installing or Reinstalling System Software” later in this chapter for instructions.

m You haven’t selected any text or set the insertion point (i).

Make sure the program you want to type in is the active program. Then place the pointer (8) in the active window and click to set an insertion point (i) or drag to select text (if you want to replace the text with your typing).

m The keyboard is not connected properly.

Tu rn off the computer using the standby power button, then check that the keyboard cable is connected properly at both ends.

If you have a keyboard with an ADB port (marked with the ◊ icon) on each end, turn off the Macintosh using the standby power button and plug the keyboard cable into the other ADB port on the keyboard. (You may have to unplug the mouse to do this.) Then restart the computer.

m The keyboard is damaged.

If you have access to another keyboard, try using it instead. (Turn the computer off before connecting it.) If the new keyboard works, there is probably something wrong with the one you replaced.

Chapter 5

You can’t start an application program or it quits unexpectedly. Or, when you try to open a program, you see a message that not enough memory is available.

One of the following is probably the cause: m The Macintosh ran out of memory.

Quit the programs that you have open and then open the program you want to use, or restart your Macintosh.

Use the Memory control panel to turn on virtual memory. For more information on virtual memory, see the “Memory” topic of Macintosh Guide, available in the Guide (h) menu.

m The program needs more memory.

Use the program’s Info window to give it more memory. For more information on increasing a program’s memory, see the “Memory” topic of Macintosh Guide, available in the Guide (h) menu.

m The program requires special hardware, and your computer doesn’t have

the hardware installed.

Check the documentation that came with the program to find out if the program requires a Macintosh with special hardware. Then check the Technical Information booklet that came with your Macintosh to find out if your computer is equipped with such special hardware, or if the hardware can be installed. Consult your Apple-authorized service provider for information on installing special hardware in your computer.

Troubleshooting

You can’t open a document, or you see a message that an application program can’t be found.

m Some documents can be opened by more than one application program.

Try starting a program that you think might be able to open the document, then choose Open from the program’s File menu to try to open the document.

m Purchase and install the correct software to use the document, or find out

if the creator of the document can convert it to a form that one of your programs can use.

m Don’t try to open the files in your System Folder. Most of the files in your

System Folder are used by your computer for internal purposes and are not intended to be opened.

m Rebuild your desktop by holding down the Option and x keys while

starting up your computer. Keep holding down the keys until you see a message asking whether you want to rebuild the desktop. Click OK.

m If the document is from a DOS computer, use the PC Exchange control

panel to specify which Macintosh program will open the document. For information about working with DOS documents on your Macintosh, see the “Using DOS Files & Disks” topic of Macintosh Guide, available in the Guide (h) menu.

You experience problems using a document from a DOS computer.

If you can’t open a DOS document using a Macintosh program, try the following:

m Open the document from within the program by choosing Open in the

program’s File menu.

m Use the PC Exchange control panel to change the document’s type to one

that can be opened by the program.

If a DOS document is displayed incorrectly, or you see strange codes or characters in the document, try one of the following:

m Your application program may have special procedures for opening and

saving documents with different file formats. See the information that came with your program or call the program’s publisher.

m Try opening the document in another program.

Chapter 5

Note: Some characters that can be displayed on the Macintosh are not accurately displayed on DOS computers, and vice versa.

For more information about working with DOS documents on your Macintosh, see the “Using DOS Files & Disks” topic of Macintosh Guide, available in the Guide (h) menu.

Repairing a damaged disk

If you see a message reporting that a disk is damaged or unreadable, you may need to repair the disk.

Try these suggestions first

If you can’t start up from a hard disk or you don’t see the hard disk icon on the desktop, try the following:

m If the hard disk is internal, shut down your Macintosh, wait at least 10

seconds, and then turn it on again.

m If the hard disk is external, make sure that it is turned on and that its cable

is connected firmly; then restart the Macintosh.

m If the hard disk is your startup disk, start up with a different startup disk.

(See the following sections, “Starting Up From a CD-ROM Disc” and “Starting Up From a Floppy Disk.”)

If, after you start up from a different disk, your hard disk’s icon appears on your desktop, reinstall system software on the hard disk (see “Installing or Reinstalling System Software” later in this chapter).

If your hard disk’s icon does not appear on your desktop, you may need to initialize the disk (see “Initializing a Hard Disk” later in this chapter).

m Check the ID numbers of all SCSI equipment connected to your computer.

Each device must have a unique ID number less than 7; the computer itself has the ID number 7, and the internal CD-ROM drive (if there is one) has the ID number 3. The ID numbers 0, 1, 2, 4, 5, and 6 are available for additional SCSI devices.

Troubleshooting

Also check that the chain of devices is terminated properly. For information on setting SCSI ID numbers and terminating a SCSI chain, see the manuals that came with your SCSI equipment.

m If none of these suggestions solves the problem, test the disk by following

the instructions given later in this section.

Starting up from a CD-ROM disc

To test, repair, or initialize a hard disk, or to install system software on a hard disk, you need to start up your computer from another disk. If your computer has a CD-ROM drive, you can start up your computer using the Macintosh Performa CD that came with your computer.

The procedure for starting up from the CD varies depending on the condition of the system software on your hard disk. To find out which procedure to use, you must turn on your Macintosh.

The steps that follow tell how to start up from a CD-ROM disc, depending on what you see on your screen.

If you see a blinking question mark on your screen

The blinking question mark means that your Macintosh is unable to find usable system software on your hard disk.

disk into the disk drive.

It takes several moments for your computer to start up from the Ut ilities disk.

Checking for damage on your internal hard disk

You can check for damage on your internal hard disk with the Internal HD Format program, which is on the Utilities floppy disk that came with your computer. If your computer has a built-in CD-ROM drive and you didn’t receive floppy disks, you can find the Internal HD Format program on the Macintosh Performa CD. You can use Internal HD Format at any time to check for damaged blocks (segments of the hard disk that cannot reliably be used to store information).

Chapter 5

1 Start up your computer from the

Utilities

floppy disk or the

Macintosh Performa CD.

See “Starting Up From a CD-ROM Disc” or “Starting Up From a Floppy Disk” earlier in this section.

2 Open the Internal HD Format program.

You may need to look in a folder called Utilities to find Internal HD Format.

3Choose Scan For Defects in the Functions menu.

If the program finds damaged blocks, it marks them so the computer will not store information in them. This process does not harm any information on the hard disk.

erase (reinitialize) the disk. For instructions on reinitializing a floppy disk, see the “Disks” topic of Macintosh Guide, available in the Guide (h) menu. For instructions on reinitializing a hard disk, see the next section, “Initializing a Hard Disk.”

If initialization doesn’t work, discard the damaged disk (if it’s a floppy disk), or take it to your Apple-authorized service provider for repair (if it’s a hard disk). If you received a copy of the Macintosh Performa CD (whether or not your computer has a CD-ROM drive), bring this disc with you to the service provider.

Troubleshooting

Initializing a hard disk

The hard disk inside your computer was initialized (formatted for use) at the factory, so you shouldn’t need to initialize it. You need to initialize a hard disk only if

m you purchase a hard disk that has not been initialized at the factory m your hard disk is damaged

If a hard disk needs to be initialized, the disk’s icon may not appear on the desktop when you start up the computer using another disk.

Chapter 5

Installing or reinstalling system software

System software is the set of programs and other files that your computer uses to start itself up, keep track of your files, and run the application programs you use. System software is kept in the System Folder. When you turn on your computer, it looks for a startup disk, which is a disk that contains the system software. The startup disk is usually the hard disk that’s inside your computer, though another hard disk or a floppy disk can also be a startup disk.

When should you install or reinstall system software?

Your Macintosh came with all the necessary system software installed on its internal hard disk, so you don’t need to install system software on that disk unless you encounter software problems.

If you have a new hard disk or a newly initialized hard disk that doesn’t contain system software, or if you want to upgrade to a more recent version of system software on a hard disk, you’ll need to install system software. See the next section, “How to Install or Reinstall System Software.”

If your hard disk already has system software installed on it but there is a problem with the disk or the software, you may see this icon in the middle of the screen:

If this icon appears, first try testing your startup hard disk and repairing any damage. To do this, follow the instructions in “Repairing a Damaged Disk” earlier in this chapter. If repairing the disk doesn’t help, you may need to reinstall system software.

Troubleshooting

How to install or reinstall system software

If your computer has a CD-ROM drive, you can install or reinstall system software by following the instructions in the Macintosh Performa CD booklet that came with your computer.

If your computer doesn’t have a CD-ROM drive and you’ve used Apple Backup to back up the contents of your hard disk, you can use Apple Restore to reinstall system software. For instructions, see “Restoring the Information on Your Hard Disk” in Chapter 4.

If your computer doesn’t have a CD-ROM drive and you have not used Apple Backup to back up the contents of your disk, try one of the following:

m If you received the Macintosh Performa CD with your computer, contact

an Apple-authorized service provider, a Macintosh user group, or another Macintosh user for access to a CD-ROM drive. Reinstall system software on your hard disk by following the instructions in the Macintosh Performa CD booklet that came with your computer.

m If you did not receive the Macintosh Performa CD with your computer,

or if you cannot get access to a CD-ROM drive, call the customer support hotline. (The phone number for the hotline is in the service and support information that came with your computer.)

Appendix A Health, Safety, and Maintenance Tips

For your own safety and that of your equipment, follow all the instructions in this chapter. Keep these instructions available for reference by you and others.

Health-related information about computer use

Muscle soreness, eye fatigue, and other discomforts and injuries sometimes associated with using computers can occur from performing any number of activities. In fact, misuse of the same muscles during multiple activities can create a problem that might not otherwise exist. For example, if you engage in nonwork activities that involve repetitive stress on the wrist—such as bicycling—and also use your computer’s keyboard improperly, you may increase your likelihood of developing wrist problems. Some individuals are at greater risk of developing these problems because of their health, physiology, lifestyle, and general exposure to stress. Work organization and conditions, such as workstation setup and lighting, also play a part in your overall health and comfort. Preventing health problems is a multifaceted task that requires careful attention to the way you use your body every hour of every day.

Read this appendix for important

health and safety instructions,

as well as tips on keeping your

computer in good working order.

The most common health effects associated with using a computer are musculoskeletal discomfort and eye fatigue. We’ll discuss each area of concern below.

Musculoskeletal discomfort

As with any activity that involves sitting for long periods of time, using a computer can make your muscles sore and stiff. To minimize these effects, set up your work environment carefully, using the guidelines that follow, and take frequent breaks to rest tired muscles. To make working with your computer more comfortable, allow enough space in your work area so that you can change position frequently and maintain a relaxed posture.

Another type of musculoskeletal concern is repetitive stress injuries (RSIs), also known as cumulative trauma disorders (CTDs). These problems can occur when a certain muscle or tendon is repeatedly overused and forced into an unnatural position. The exact causes of RSIs are not totally understood, but in addition to awkward posture, such factors as the amount of repetition, the force used in the activity, the individual’s physiology, workplace stress level, and lifestyle may affect the likelihood of experiencing an RSI.

RSIs did not suddenly arise when computers were invented; tennis elbow and writer’s cramp, for example, are two RSIs that have been with us for a long time. Although less common than other RSIs, one serious RSI discussed more often today is a wrist problem called carpal tunnel syndrome, which may be aggravated by improper use of computer keyboards. This nerve disorder results from excessive pressure on the median nerve as it passes through the wrist to the hand.

This section offers advice on setting up your work area to enhance your comfort while you use your computer. Since the effects of repetitive movements associated with using a computer can be compounded by those of other work and leisure activities to produce or aggravate physical problems, proper use of your computer system must be considered as just one element of a healthy lifestyle.

No one, of course, can guarantee that you won’t have problems even when you follow the most expert advice on using computer equipment. You should always check with a qualified health specialist if muscle, joint, or eye problems occur.

Appendix A

Eye fatigue

Eye fatigue can occur whenever the eyes are focused on a nearby object for a long time. This problem occurs because the eye muscles must work harder to view an object that’s closer than about 20 feet (6 meters). Improper lighting can hasten the development of eye fatigue. Although eye fatigue is annoying, there’s no evidence that it leads to permanent damage.

Whenever you’re engaged in an activity that involves close-up work—such as reading a magazine, doing craft work, or using a computer—be sure to have sufficient glare-free lighting and give your eyes frequent rest breaks by looking up and focusing on distant objects. Remember to have your eyes examined regularly.

To prevent discomfort and eye fatigue:

m Arrange your work space so that the furniture is properly adjusted for you

and doesn’t contribute to an awkward working posture.

m Ta ke frequent short breaks to give your muscles and eyes a chance to rest.

Arranging your office

Here are some guidelines for adjusting the furniture in your office to accommodate your physical size and shape.

m An adjustable chair that provides firm, comfortable support is best. Adjust

the height of the chair so your thighs are horizontal and your feet flat on the floor.

The back of the chair should support your lower back (lumbar region). Follow the manufacturer’s instructions for adjusting the backrest to fit your body properly.

m When you use the computer keyboard, your shoulders should be relaxed.

Your upper arm and forearm should form an approximate right angle, with your wrist and hand in roughly a straight line.

Health, Safety, and Maintenance Tips

You may have to raise your chair so your forearms and hands are at the

proper angle to the keyboard. If this makes it impossible to rest your feet flat on the floor, you can use a footrest with adjustable height and tilt to make up for any gap between the floor and your feet. Or you may lower the desktop to eliminate the need for a footrest. Another option is to use a desk with a keyboard tray that’s lower than the regular work surface.

m Position the mouse at the same height as your keyboard. Allow adequate

space to use the mouse comfortably.

m Arrange the monitor so the top of the screen is slightly below your eye

level when you’re sitting at the keyboard. The best distance from your eyes to the screen is up to you, although most people seem to prefer 18 to 28 inches (45 to 70 cm).

m Position the monitor to minimize glare and reflections on the screen from

overhead lights and windows. You may want to use a tiltable monitor stand. The stand lets you set the monitor at the best angle for viewing, helping to reduce or eliminate glare from lighting sources you can’t move.

Appendix A

Avoiding fatigue

m Change your seated position, stand up, or stretch whenever you start to feel

tired. Frequent short breaks are helpful in reducing fatigue.

m Use a light touch when typing or using a mouse and keep your hands and

fingers relaxed.

m Some computer users may develop discomfort in their hands, wrists, or

arms after intensive work without breaks. If you begin to develop chronic pain or discomfort in your hands, wrists, or arms, consult a qualified health specialist.

m Allow adequate work space so that you can use your keyboard and mouse

comfortably. Place papers or other items so you can view them easily while using your computer. A document stand may make reading papers more comfortable.

m Eye muscles must work harder to focus on nearby objects. Occasionally

focus your eyes on a distant object, and blink often while you work.

m Clean your screen regularly. Keeping the screen clean helps reduce

unwanted reflections.

What about electromagnetic emissions?

There has been recent public discussion of the possible health effects of prolonged exposure to extremely low frequency (ELF) and very low frequency (VLF) electromagnetic fields. Such fields are associated with electromagnetic sources such as television sets, electrical wiring, and some household appliances—as well as computer monitors.

Apple has reviewed scientific reports and sought the counsel of government regulatory agencies and respected health organizations. Based on the prevailing evidence and opinions, Apple believes that the electric and magnetic fields produced by computer monitors do not pose a health risk.

In response to those customers who wish to reduce their exposure to electromagnetic fields, Apple has lowered the emission levels of our products. We are also actively encouraging further scientific research so we can continue to promote the health and safety of our customers and employees.

Health, Safety, and Maintenance Tips

Safety instructions

For your own safety and that of your equipment, always take the following precautions.

Turn off the computer completely and disconnect the power plug (by pulling the plug, not the cord) if any of the following conditions exists:

m the power cord or plug becomes frayed or otherwise damaged m you spill something into the case m your Macintosh is exposed to rain or any other excess moisture m your Macintosh has been dropped or the case has been otherwise damaged m you suspect that your Macintosh needs service or repair m you want to clean the case (use only the recommended procedure

Be sure that you always do the following:

m Keep your Macintosh away from sources of liquids, such as wash basins,

m Protect your Macintosh from dampness or wet weather, such as rain, snow,

described later in this chapter)

bathtubs, shower stalls, and so on.

and so on.

Appendix A

m Read all the installation instructions carefully before you plug your

Macintosh into a wall socket.

m Keep these instructions handy for reference by you and others. m Follow all instructions and warnings dealing with your system.

WARNING

Electrical equipment may be hazardous if misused. Operation of this product, or similar products, must always be supervised by an adult. Do not allow children access to the interior of any electrical product and do not permit them to handle any cables.

Handling your computer equipment

Follow these guidelines for handling your computer and its components: m When setting up your computer, place components on a sturdy, flat surface,

and carefully follow all setup instructions.

m When connecting or disconnecting a cable, always hold the cable by its

connector (the plug, not the cord).

m Tu rn off your computer and all its components before connecting or

disconnecting any cables to add or remove any component. Failure to do so could seriously damage your equipment.

m Never force a connector into a port. If the connector and port do not join

with reasonable ease, they probably don’t match. Make sure that the connector matches the port and that you have positioned the connector correctly in relation to the port.

m Ta ke care not to spill any food or liquid on the computer, keyboard, mouse,

or other components. If you do, turn your computer off immediately and unplug it before cleaning up the spill. Depending on what you spilled and how much of it got into your equipment, you may have to bring your equipment to an Apple-authorized service provider.

m Protect the computer and its components from direct sunlight and rain or

other moisture.

m Keep all ventilation openings clear and unobstructed. Without proper air

circulation, components can overheat, causing damage or unreliable operation.

WARNING

This equipment is intended to be electrically grounded. Your Macintosh is equipped with a three-wire grounding plug—a plug that has a third (grounding) pin. This plug will fit only a grounded AC outlet. This is a safety feature. If you are unable to insert the plug into the outlet, contact a licensed electrician to replace the outlet with a properly grounded outlet. Do not defeat the purpose of the grounding plug!

Health, Safety, and Maintenance Tips

Handling the monitor

Follow these procedures for handling a monitor: m Turn down the screen brightness control if you leave the computer turned

on for extended periods. If the brightness is not turned down, the image on the screen could “burn in” and damage the screen.

You can also use a “screen saver” program, which dims or varies the image on the screen when the computer has been idle for a specified period of time. These programs are available from independent suppliers and user groups.

m Make sure that the ventilation openings on the computer and the monitor

are clear and unobstructed.

m Some large monitors cannot safely be placed on top of the computer.

Check the instructions that came with the monitor for setup information.

m If there is interference on the monitor’s screen or on a television or radio

near your computer, move the affected equipment farther away.

Handling the keyboard

Ta ke care not to spill any liquid on the keyboard. If you do, turn off your computer immediately.

m If you spill liquid that is thin and clear, unplug the keyboard, turn it upside

down to let the liquid drain out, and let it dry for 24 hours at room temperature. If, after you take these steps, the keyboard doesn’t work, take it to an Apple-authorized service provider for repair.

m If you spill liquid that is greasy, sweet, or sticky, unplug the keyboard and

take it to an Apple-authorized service provider for repair.

getting moisture in any openings.

m Don’t use aerosol sprays, solvents, or abrasives.

Cleaning the computer case

To clean the case, do the following:

1 Turn off the computer completely and then disconnect the power plug. (Pull the plug, not

the cord.)

2Wipe the surfaces lightly with a clean, soft cloth dampened with water.

Cleaning the monitor

To clean the screen, put household glass cleaner on a soft cloth and wipe the screen. Don’t spray the cleaner directly on the screen, because the liquid might drip into the monitor or computer.

Cleaning the mouse

The mouse contains a small ball that must roll smoothly for the mouse to work properly. You can keep this ball free of dirt and grease by using the mouse on a clean, lint-free surface and cleaning it occasionally.

You need a few cotton swabs and a clean, soft, lint-free cloth.

1 Turn off your computer.

Health, Safety, and Maintenance Tips

2 Turn the mouse upside-down and turn the plastic ring on the bottom counterclockwise

to disengage it.

On some mouse devices, you may need to press the plastic ring (rather than turn it) to disengage it. If you cannot disengage the ring, your mouse may be locked. See “Locking and Unlocking the Mouse,” next in the appendix.

3 Turn the mouse right-side up with one hand and catch the ring and the ball with your

other hand.

4Clean the three small rollers inside the mouse with a cotton swab moistened with water.

Rotate the rollers to clean all around them.

5Wipe the mouse ball with a clean, soft, dry, and lint-free cloth.

6If necessary, wash the mouse ball with warm soapy water (use a mild soap such as a

dishwashing liquid) and then dry the mouse ball thoroughly.

7Gently blow into the mouse case to remove any dust that has collected there.

8Put the ball and the ring back in place.

Your mouse should roll smoothly across your mouse pad or desk. If it doesn’t, repeat these instructions carefully.

on installing an expansion card

in your computer.

Appendix B Installing an Expansion Card

Expansion cards are printed circuit boards that can be installed in your computer to give it special capabilities, such as enhanced video capabilities, networking and communications, and additional processing power.

If you purchased an expansion card separately from your computer, you can install it by following the instructions that came with the card, or by following the instructions in this appendix. However, be sure to read this appendix for instructions that may be specific to your computer.

Cards fit into slots on the computer’s logic board, the board that holds the

components that make your computer work. There are three types of slots on your computer’s logic board, each labeled on the board:

m an LC-compatible 68030 processor-direct slot (PDS) for most

expansion cards

m a communication slot for an internal modem or an Ethernet card m a video-in slot for a card that brings signals into the computer from a

videocassette recorder (VCR), laserdisc player, video camera, or similar device

Appendix B

This appendix contains instructions for installing a PDS card or a communication card. To install a video input card or a TV tuner card, follow the instructions that came with the card.

WARNING

To avoid damaging your computer and expansion card, do not attempt to install any expansion card without first checking the documentation for that card. If the documentation specifies that an Apple-certified technician must install the card (usually because the installation requires special training or tools), consult the service and support information that came with your computer for instructions on how to contact an Apple-authorized service provider or Apple for assistance. If you attempt to install the card yourself, any damage you may cause to the computer or card will not be covered by the limited warranty on your computer. If the card is not an Apple-labeled product, check with an Apple-authorized dealer or service provider to see if you can install it yourself.

Installing an expansion card involves three steps:

m opening the computer m inserting the card into a specific slot m closing the computer
