Using Your Modem

Your computer comes with an Apple 56K v.92 modem installed. To connect the modem, plug one end of the phone cord or RJ-11 cable into the modem port on the computer and the other end into a standard RJ-11 telephone wall jack.

Make sure you connect to an analog phone line—the kind used typically in homes. The modem will not work with a digital phone line.

Warning: Do not connect a digital telephone line to the modem as it could damage the modem. Contact your telephone service provider if you are unsure whether you have a digital telephone line.

For information on how to establish an Internet connection, see Appendix C, “Connecting to the Internet,” on page 79. More information about the internal modem is also available in Mac OS Help.

Connecting Speakers and Audio Devices

Your PowerBook comes with two built-in speakers, a built-in microphone, an audio line in/optical digital audio in port, and a headphone/optical digital audio out port.

Note: While devices are plugged in, sound won’t come through your built-in speakers. Unplug any headphones or speakers to hear the computer speakers.

You can connect external speakers, headphones, 5.1 surround systems, and other sound output devices to the headphone/optical digital audio out port. The port is a stereo 3.5 mini-phono jack.

You can record sound onto your hard disk using the built-in microphone located under the left speaker grille. You can also connect external microphones or other audio equipment to the audio line in/optical digital audio in port. The port is a stereo 3.5 mini-phono jack, which does not provide power to a connected device, so you must use self-powered peripherals. Using a Toslink jack-to-miniplug adapter, you can use a Toslink cable to connect Digital Audio Tape (DAT) decks or digital instruments to input and mix your own music.

For applications, such as iMovie, that can record sounds, use the Sound pane of System Preferences to select the audio input device you want to use, including microphones connected via USB.
