Local area networks
Connecting to a local area network (LAN) requires an 8-pin, RJ-45 network cable (not included). If
the network cable contains noise suppression circuitry (1), which prevents interference from TV and
radio reception, orient the circuitry end of the cable (2) toward the computer.
NOTE The computer may look different from the illustrations in this guide. The location of
the network jack varies by model.
To connect the network cable:
1. Plug the network cable into the network jack (1) on the computer.
