1 Using the modem (select models only)

The modem must be connected to an analog telephone line using a 6-pin, RJ-11 modem cable (included
with select models only). In some countries, a country-specific modem cable adapter (included with
select models only) 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.
