Using Your Modem
Your Macintosh may come with an Apple 56K internal modem installed.
To connect the Apple 56K internal modem, plug one end of a phone cord into the modem
port on the back of the computer and the other end into a standard RJ-11 telephone wall jack.
Connecting to the Internet Via a Service Provider
Before you can connect to the Internet using your modem, you must record your service
provider information in the Network Preferences of the Mac OS X System Preferences. When
you first start up your computer, the Setup Assistant guides you through recording these
settings. To record or change these settings later, do the following:
1 Choose System Preferences from the Apple (K) menu and open the Network pane.
2 Click the PPP tab and enter information about your service provider account.
3 Click the Modem tab, choose the modem settings you want, and click Apply Now.
4 Close the System Preferences panel.
Your computer is now set up to connect with your service provider. You don’t need to enter
these settings again.
To establish a connection with your service provider:
m Open the Internet Connect application in your Applications folder and click Connect.
More information about the internal modem is available in Mac Help.
Using an External USB Modem
To connect an external USB modem, use a USB cable to connect the modem to an available
USB port on the keyboard, computer, USB monitor, or USB hub.
Check the documentation that came with the modem to see if it needs to be plugged into a
power outlet. Also look for instructions about installing modem software and connecting the
modem to a telephone line.

Important Make sure you connect the internal modem to an analog phone line—the kind
used typically in homes. The modem will not work with a digital phone line.
Warning Disconnect your modem from the phone jack during lightning or thunder
storms. This will prevent a voltage overload from damaging the modem.
