Regulatory Notes and Statements
Wireless LAN, Health and Authorization for use
Radio frequency electromagnetic energy is emitted from Wireless LAN devices. The energy levels of these emissions, however,
are far much less than the electromagnetic energy emissions from wireless devices such as mobile phones. Wireless LAN
devices are safe for use by consumers because they operate within the guidelines found in radio frequency safety standards and
recommendations. The use of Wireless LAN devices may be restricted in some situations or environments, such as:
• On board an airplane, or
• In an explosive environment, or
• In situations where the interference risk to other devices or services is perceived or identified as harmful.
In cases in which the policy regarding use of Wireless LAN devices in specific environments is not clear (e.g., airports,
hospitals, chemical/oil/gas industrial plants, private buildings), obtain authorization to use these devices prior to operating the
equipment.

Before Using the Wireless LAN
This manual describes the procedures required to properly setup and configure the optional integrated
Wireless LAN Mini Card device (referred to as “WLAN device” in the rest of the manual). Before using
the WLAN device, read this manual carefully to ensure it's correct operation.
Wireless LAN Devices Covered by this Document
This document is applicable to systems containing one of the following WLAN devices:
• Integrated Atheros AR5BHB63 (802.11 b/g)
Characteristics of the WLAN Device
• The WLAN device is a Mini-PCI card attached to the main board of the mobile computer.
• The WLAN device operates in license-free RF bands, eliminating the need to procure an FCC operating
license. The WLAN operates in the 2.4GHz Industrial, Scientific, and Medical (ISM) RF band and the lower,
middle.
• The WLAN device is capable of four operating modes, IEEE802.11b, IEEE802.11g.
• The WLAN device is Wi-Fi certified and operate (as applicable) at 54 Mbps in IEEE802.11g
mode; and 11 Mbps in IEEE802.11b mode.
• The WLAN device supports the following encryption methods - WEP, TKIP, CKIP, and AES encryption.
• The Wireless LAN device is compliant with the following standards: WPA, WPA2, CCX1.0, CCX2.0, CCX3.0,
and CCX4.0.
145 - Before Using the Wireless LAN
Wireless LAN Modes Using this Device
Ad Hoc Mode
“Ad Hoc Mode” refers to a wireless network architecture where wireless network connectivity between
multiple computers is established without a central wireless network device, typically known as Access
Point(s). Connectivity is accomplished using only client devices in a peer-to-peer fashion. That is why Ad
Hoc networks are also known as peer-to-peer networks. Ad Hoc networks are an easy and inexpensive
method for establishing network connectivity between multiple computers.
Ad Hoc mode requires that the SSID (service set identifier), network authentication, and encryption key
settings are identically configured on all computers in the Ad Hoc network.
Ad Hoc Mode Network
146 - Before Using the Wireless LAN
Access Point (Infrastructure) Mode
Infrastructure mode refers to a wireless network architecture in which devices communicate with wireless
or wired network devices by communicating through an Access Point. In infrastructure mode, wireless
devices can communicate with each other or with a wired network. Corporate wireless networks operate
in infrastructure mode because they require access to the wired LAN in order to access computers,
devices, and services such as file servers, printers, and databases.

How to Handle This Device
The WLAN device is an optional device that may come pre-installed in your mobile computer. Under
normal circumstances, it should not be necessary for you to remove or re-install it. The Operating System
that your mobile computer comes with has been pre-configured to support the WLAN device.
Wireless Network Considerations
• The WLAN device supports IEEE802.11b and IEEE802.11g.
• The WLAN device operates in the 2.4 GHz ISM band.
• Microwave ovens may interfere with the operation of WLAN devices since they operate in the same 2.4 GHz
frequency range as IEEE802.11b/g devices.
• Wireless devices that transmit in the 2.4 GHz range may interfere with operation of WLAN devices in
IEEE802.11b/g modes. Symptoms of interference include reduced throughput, intermittent disconnects,
and many frame errors. It is HIGHLY recommended that these interfering devices be powered off to ensure
proper operation of the WLAN device.
Deactivating the WLAN Device
Disconnecting the WLAN device may be desired in certain circumstances (to extend battery life) or where
certain environments require it (i.e., hospitals, clinics, airplanes, etc.). The WLAN device can be
deactivated by using the Wireless On/Off key (Fn+F2), and it can be disconnected in Windows using the
WLAN icon in the system tray (Note that disconnecting via the icon in the system tray does not turn off the radio;
it continues to transmit and receive even though it’s not connected.).
BEFORE USING THE WIRELESS LAN DEVICE, YOU MUST FIRST INSTALL CLICKME! TO ENSURE THAT THE
CORRECT SOFTWARE FOR YOUR DEVICE IS INSTALLED. SEE SEE “INSTALLING CLICK ME!” ON PAGE 45.
148 - Before Using the Wireless LAN
