Wireless guidance
Low power, Radio transmitting type devices (radio frequency (RF) wireless communication 
devices), may be present (embedded) in your notebook system. These devices may operate in the 
2.4 GHz (i.e. 802.11b/g LAN & Bluetooth), 5.2 GHz (i.e. 802.11a LAN), and traditional cellular or 
PCS cellular bands (i.e. Cellular data modem). The following section is a general overview of 
considerations while operating a wireless device.
WarningRadio frequency wireless communication can interfere with equipment on 
commercial aircraft. Current aviation regulations require wireless devices to be 
turned off while traveling in an airplane. IEEE 802.11 (also known as wireless 
Ethernet or WiFi), wireless Internet, and Bluetooth communication devices are 
examples of devices that provide wireless communication.
WarningIn environments where the risk of interference to other devices or services 
is harmful or perceived as harmful, the option to use a wireless device may be 
restricted or eliminated. Airports, Hospitals, and Oxygen or flammable gas laden 
atmospheres are limited examples where use of wireless devices may be 
restricted or eliminated. When in environments where you are uncertain of the 
sanction to use wireless devices, ask the applicable authority for authorization 
prior to use or turning on the wireless device.
WarningIf your notebook came equipped with an internal embedded wireless 
device, do not operate the wireless device unless all covers and shields are in place 
and the notebook is fully assembled.
CautionWireless devices are not user serviceable. Do not modify them in any way. 
Modification to a wireless device will void the authorization to use it. Please 
contact Gateway for service.
