Usage environment and your health
Integrated wireless cards emit 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 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 reect the consensus of the scientic 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 might be restricted by the proprietor
of the building or responsible representatives of the organization. These situations and areas might 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, such
as pace makers.
In any other environment where the risk of interference to other devices or services is perceived or
identied as harmful.
If you are uncertain of the policy that applies to the use of wireless devices in a specic organization (such as
airport or hospital), you are encouraged to ask for authorization to use integrated wireless cards prior to
turning on the computer.
