Because Wireless LAN PCI Express Mini Card and Bluetooth Daughter Card
operates 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:
v Using the integrated wireless cards on board of airplanes, or in hospitals
v 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
