Operation Manual

The Ethernet connector has two indicators that show the status of the network connection. When the
green indicator is on, the computer is connected to a LAN. When the yellow indicator blinks, data is
being transmitted.
Wireless connections
Wireless connection is the transfer of data without the use of cables but by means of radio waves only.
Using the wireless-LAN connection
A wireless local area network (LAN) covers a relatively small geographic area, such as an office building or a
house. Devices based on the 802.11 standards can connect to this type of network.
Your computer comes with a built-in wireless network card to help you establish wireless connections and
monitor the connection status.
To establish a wireless-LAN connection, do the following:
1. Turn on the wireless feature. See “Using the special keys” on page 20.
2. Click the wireless-network-connection-status icon in the Windows notification area. A list of available
wireless networks is displayed.
3. Double-click a network to connect to it. Provide required information if needed.
The computer automatically connects to an available and remembered wireless network when the location
changes. If the available wireless network is secured, provide the password as required. For more
information, see the Windows help information system.
Tips on using the wireless-LAN feature
To achieve the best connection, use the following guidelines:
• Place your computer so that there are as few obstacles as possible between the wireless-LAN access
point and the computer.
• Open your computer cover to an angle of slightly more than 90 degrees.
Checking the wireless-LAN connection status
You can check the wireless-LAN connection status through the wireless-network-connection-status icon in
the Windows notification area. The more bars encompassed, the better the signal is.
Using the Bluetooth connection
Bluetooth can connect devices that are within a short distance from one another. Bluetooth is commonly
used in the following scenarios:
• Connecting peripheral devices to a computer
• Transferring data between hand-held devices and a personal computer
• Remotely controlling and communicating with devices such as mobile phones
Depending on the model, your computer might support the Bluetooth feature. To transfer data through the
Bluetooth feature, do the following:
Note: It is not recommended to use the wireless feature (the 802.11 standards) of your computer
simultaneously with a Bluetooth option. The data transmission speed can be delayed and the performance of
the wireless feature can be degraded.
