Do not plug a telephone cable into the network (Ethernet) port on your computer.
If the network (Ethernet) port is connected to one of the telephone lines mentioned below, high electric current to the port may cause damage, 
overheating, or fire.

- Home (intercom speakerphone) or business-use telephone lines (multi-line business telephone)

- Public telephone subscriber line

- PBX (private branch exchange)

Using the Wireless LAN (WLAN)

Using the Sony Wireless LAN (WLAN), all your digital devices with the built-in WLAN function communicate freely with each 
other through a network. A WLAN is a network in which a user can connect to a Local Area Network (LAN) through a wireless 
(radio) connection. This eliminates the need to pull cables or wires through walls and ceilings.

The Sony WLAN supports all normal Ethernet connectivity, but with the added benefits of mobility and roaming. You can still 
access information, Internet/intranet and network resources, even in the middle of a meeting, or as you move from one place 
to another.

You can communicate without an access point, which means that you can communicate with a limited number of computers 
(ad-hoc). Or you can communicate through an access point, which allows you to create a full infrastructure network.

To use the wireless LAN function

To use the wireless LAN function, you first need to set up the wireless LAN function.
