radio frequency electromagnetic energy like other radio devices. However,
the level of energy emitted is far much less than the electromagnetic energy
emitted by wireless devices like for example mobile phones.
Due to the fact that wireless LAN PCI Express Mini Card and Bluetooth
Daughter Card operate within the guidelines found in radio frequency
safety standards and recommendations, Lenovo believes the integrated
wireless cards are safe for use by consumers. These standards and
recommendations reflect the consensus of the scientific community and
result from deliberations of panels and committees of scientists who
continually review and interpret the extensive research literature.
In some situation or environment, the use of wireless LAN PCI Express
Mini Card or Bluetooth Daughter Card may be restricted by the proprietor
of the building or responsible representatives of the organization. These
situations may for example include:
Using the integrated wireless cards on board of airplanes, or in hospitals
In any other environment where the risk of interference to other devices
or services is perceived or identified as harmful.
If you are uncertain of the policy that applies on the use of wireless devices
in a specific organization (e.g., airport or hospital), you are encouraged to
ask for authorization to use wireless LAN PCI Express Mini Card or
Bluetooth Daughter Card prior to turning on the computer.
