Chapter 2 Using Your Computer 31

Headphone Jack

You can plug headphones into the computer’s headphone jack. When a plug is inserted
into this jack, your internal built-in speaker is muted.
Important: Do not plug line-out devices into the headphone jack. Use the analog line-
out port on the back instead.

Analog Audio Ports

You can connect external microphones or other audio equipment to the analog
minijacks on the back of the computer for line in and line out.
Use the Sound pane of System Preferences to select the audio input or output device
you want to use.
Using Your Optical Drive
You can install or use software from CDs or DVDs using your optical drive. You can play
multimedia on CD discs and music from audio CDs, and write music, documents, and
other digital files to CD-R and CD-RW discs. You can also play DVD movies and use
most DVD discs.
If your computer has a SuperDrive, you can also burn your home movies to make video
DVDs that can be played in most home DVD players, or you can save documents or
other digital files to blank DVD-R, DVD-RW, DVD+R, DVD+RW, and DVD+R Double Layer
(DL) discs using the Finder or iDVD. You can store nearly twice as much data (8.54 GB)
on a DVD+R DL disc.
Note: If you have older software that comes on floppy disks, contact the software
manufacturer to see if the software is available on a CD, or purchase an external USB
floppy disk drive for your Power Mac G5 from your Apple Authorized Reseller, an Apple
retail store, or online from the Apple Store at www.apple.com/store.

Inserting a Disc

To install or use programs from a CD or DVD:
1With the computer turned on, press the Media Eject (C) key on your Apple Keyboard to
open the drive.
2Place a disc in the tray, with the label facing up, and make sure the disc is lying flat.
3Press the Media Eject (C) key again or gently push the tray in to close it.
When the icon for the disc appears on the screen, the disc is ready to use.

Ejecting a Disc

You can eject a disc by dragging the disc icon to the Trash, or by pressing the Media
Eject (C) key on your Apple Keyboard. You can also eject a disc by holding down the
mouse button while restarting your computer.
