Modem
Your computer comes with a 56K V.92 internal fax/modem and a phone jack (RJ-11),
which is located on the left side of your computer.
Use a telephone cable to connect the computer to the telephone wall outlet.
Connecting the Modem
1. Plug one end of the phone line into the modem port located on the rear side
of the computer. (For EMI compliance, you need to clip the included EMI
CORE to the phone line.)
2. Plug the other end of the line into the analog phone wall outlet.
Depending on where your computer is used, you may need to change settings in the
modem. The correct setting will allow you to maintain a stable connection in a country
where its telecommunication system may be different to others.
