9 Modem and LAN

Using a modem

The modem must be connected to an analog telephone line using a 6-pin, RJ-11 modem cable (purchased separately). 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.
