10 Modem and Local Area Network
Modem
The modem in the computer must be connected to an analog telephone line using a 6-pin, RJ-11
modem cable. In some countries, a country-specific modem cable adapter is also required. Jacks for
digital PBX systems may resemble analog telephone jacks, but they are not compatible with the
modem.
WARNING! Connecting the internal analog modem to a digital line can permanently damage
the modem. Immediately disconnect the modem cable if you accidentally connect it to a digital
line.
If the modem cable contains noise suppression circuitry (1), which prevents interference from TV and
radio reception, orient the circuitry end (2) of the cable toward the computer.
NOTE The computer may look different from the illustrations in this guide. The location of
the modem jack varies by model.
