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 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.
Connecting a modem cable
WARNING! To reduce the risk of electric shock, fire, or damage to the equipment, do not plug a
modem cable (included with select models only) or telephone cable into the RJ-45 (network) jack.
To connect a modem cable:
1. Plug the modem cable into the modem jack (1) on the computer.
2. Plug the modem cable into the RJ-11 telephone wall jack (2).
Connecting a country-specific modem cable adapter
Telephone jacks vary by country. To use the modem and the modem cable (included with select
models only) outside the country in which you purchased the computer, you must obtain a country-
specific modem cable adapter (included with select models only).
