Using Your Modem
Your Macintosh comes with an Apple 56K V.90 internal modem installed.
To connect the Apple 56K V.90 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.
More information about the internal modem is available in Mac Help (in the Help menu).
Using an External USB Modem
To connect an external USB modem, use a USB cable to connect the modem to a free 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 destructive voltage overload from damaging the modem.
