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 indust

3 Connect the equipment to an outlet on a circuit different from the one the receiver is connected to.
4 Consult the dealer or an experienced radio/TV technician for help.
FCC Radio Frequency Exposure statement
The available scientific evidence does not show that any health problems are associated with using low power wireless devices. There is no
proof, however, that these low power wireless devices are absolutely safe. Low power wireless devices emit low levels of radio frequency
energy (RF) in the microwave range while being used. Whereas high levels of RF can produce health effects (by heating tissue), exposure to
low-level RF that does not produce heating effects causes no known adverse health effects. Many studies of low-level RF exposure have not
found any biological effects. Some studies have suggested that some biological effects might occur, but such findings have not been confirmed by additional research. The wireless LAN radio device has been t
forth for an uncontro
lled equipment and meets the FCC radio frequency (RF) Exposure Guidelines in Supplement C to OET65.

Export restrictions
This product or software contains encryption code which may not be exported or transferred from the US or Canada without an approved US
Department of Commerce export license. This device complies with Part 15 of FCC Rules., as well as ICES 003 B / NMB 003 B. Operation is
subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesirable operation. Modifications not expressly authorized by Fujitsu America,
Incorporated, may invalidate the user's right to operate this equipment.

Before Using the Optional Wireless LAN
This manual describes the procedures required to properly set up and configure the optional integrated WLAN+BT
combo radio module(referred to as "WLAN device" in the rest of the manual). Before using the WLAN device, carefully
read this manual to ensure it's correct operation and to follow any special instructions that may be required to comply
with mandatory regulatory requirements. Keep this manual in a safe place for future reference.
Wireless LAN Devices Covered by this Document
This document is applicable to systems containing one of the following devices:
• Intel® Dual Band Wireless-N 7260
• Qualcomm Atheros® AR946x Wireless Network Adapter
Characteristics of the WLAN Device
• The WLAN devices are PCI Express Mini cards attached to the main board of the mobile computer.

The WLAN operates in the 2.4GHz Industrial, Scientific, and Medical (ISM) RF band and the lower, middle, and
upper bands of the 5GHz Unlicensed National Information Infrastructure (UNII) bands.
• The WLAN devices are capable of four operating modes, IEEE802.11a, IEEE802.11b, IEEE802.11g, and
IEEE802.11n
• The WLAN device is Wi-Fi certified and operate (as applicable) at a the maximum data rate of 450 Mbps in
IEEE802.11n mode (300 Mbps in this configuration); 54 Mbps in IEEE802.11g mode; and 11 Mbps in
IEEE802.11b mode.

Wireless LAN Modes Using this Device
Ad Hoc Mode Network
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, network authentication, and encryption key
settings are identically configured on all computers in the Ad Hoc network.

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 WLAN in order to access services, devices, and computers (e.g., file servers,
printers, 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.
• Integrated Intel Centrino and Qualcomm Atheros wireless LAN devices support IEEE802.11a, IEEE802.11b,
EEE802.11g and EE802.11n.
• The WLAN device operates in the 2.4 GHz ISM band and the 5 GHz lower, middle, and upper UNII bands.
• 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/n devices. Interference by microwaves does not occur with IEEE802.11a
radio which operates in the 5 GHz RF band.
• Wireless devices that transmit in the 2.4 GHz range may interfere with operation of WLAN devices in
IEEE802.11b/g/n 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/Disconnecting 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 Device On/Off Switch, 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.)
A - 45 - Before Using the Optional Wireless LAN
Deactivation Using the Wireless Device On/Off Switch
WLAN Switch
The WLAN device can be deactivated quickly and efficiently by toggling the Wireless Device On/Off Switch to the Off
position. The Wireless Device On/Off switch has no effect on non-Wireless LAN models.
Figure 3. Wireless Device On/Off Switch Location
Disconnection Using the Icon in the Taskbar
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.
1 Right-click the WLAN icon in the taskbar at the bottom right of your screen.
2 Choose Disconnect from a network.
Activating the WLAN Device
Activation of the WLAN device can be accomplished using the same methods as the deactivation process
• Using the Wireless Device On/Off Switch
• In Windows, by right-clicking the WLAN icon then clicking “Connect to a network”
