[. . . ] After 30 seconds, the connection is established. For more information about setting up an access point, see the documentation supplied with your Access Point. The WPA key needs to contain at least 8 characters. nN 50 Using your VAIO computer Using the WiFi protected access (WPA) WPA is a wireless security enhancement that allows you to transfer data in a highly secure way*. To use WPA on your notebook, proceed as follows: 1 2 3 4 5 6 7 Turn on the Wireless LAN switch. Right-click the network icon on the taskbar displaying Wireless Network Connection. Select View available network connections. The Wireless Network Properties dialog box appears. Select the wireless network to which you want to connect. The network key should be at least 8 characters long. Fill in exactly the same Network key again, for confirmation. The connection is established. * For more information on the access point, please refer to its manual. In Ad-hoc mode, WPA security cannot be used (specifications in the standard itself). In France, only certain channels are legally allowed when using WLAN outdoors. For more information, see the Wireless LAN Regulations. nN 51 Using your VAIO computer Wireless LAN channel selection In a 802. 11b/g configuration, channel 1 to 13 can be used. (a) With an Access Point ("Infrastructure") The channel used will be the channel selected by the Access Point. ATT: For details on how to select the channel that will be used by the Access Point, please refer to the corresponding Instruction Manual. (b) Without Access Point ("Ad-Hoc") If the Wireless connection is initiated by the VAIO computer, channel 11 will be selected. ATT: In France, outdoors, Wireless LAN connections are only allowed on certain channels. For details, please refer to the Wireless LAN Regulations. If the Wireless connection is initiated by a peer Wireless LAN equipment, the Wireless LAN communication will make use of the channel selected by the peer Wireless LAN equipment. !The 2. 4 GHz bandwidth used by wireless LAN compatible devices is also used by other various devices. Although technologies to minimize interference from other devices that uses the same bandwidth are employed on wireless LAN compatible devices, such interference may cause lower communication speed, narrower communication range, or broken wireless connections. The communication speed varies depending on the distance between communication devices, existence of obstacles between such devices, the device configuration, the radio conditions, and the software in use. In addition, communications may be cut off depending on the radio conditions. The communication range varies depending on the actual distance between communication devices, existence of obstacles between such devices, the radio conditions, the ambient environment that includes existence of walls and materials of such walls, and the software in use. Deploying IEEE 802. 11b and IEEE 802. 11g products on the same wireless network may reduce the communication speed due to radio interference. Taking this into consideration, the IEEE 802. 11g products are designed to reduce the communication speed to ensure communications with IEEE 802. 11b products. When the communication speed is not as fast as expected, changing the wireless channel on the access point may increase the communication speed. nN 52 Using your VAIO computer Troubleshooting Wireless LAN I cannot use the Wireless LAN functionality Check if the Wireless LAN switch is turned on. The Wireless LAN Access Point and your computer cannot communicate Check if the Wireless LAN switch is turned on. [. . . ] It can also be potentially dangerous to play loud music while walking, especially at pedestrian crossings. Preventing hearing damage ­ Avoid using headphones at high volume. Hearing experts advise against continuous, loud and extended play. If you experience a ringing in your ears, reduce the volume or discontinue use. nN 109 Precautions On handling Memory Sticks Do not touch the Memory Stick connector with your finger or metallic objects.
