Due to the fact that integrated wireless cards operate within the guidelines found in radio frequency safety
standards and recommendations, Lenovo believes they are safe for use by consumers. These standards and
recommendations reect the consensus of the scientic 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 integrated wireless cards may be restricted by the proprietor
of the building or responsible representatives of the organization. These situations and areas may for
example include:
• Using the integrated wireless cards on board of airplanes, in hospitals or near petrol stations, blasting
areas (with electro-explosive devices), medical implants or body-worn electronic medical devices, e.g.
pace makers.
• In any other environment where the risk of interference to other devices or services is perceived or
identied as harmful.
If you are uncertain of the policy that applies on the use of wireless devices in a specic organization (e.g.,
airport or hospital), you are encouraged to ask for authorization to use integrated wireless cards prior to
turning on the computer.
