Usage environment and your health
This computer contains integrated wireless cards that operate within the guidelines identified by radio
frequency (RF) safety standards and recommendations; therefore, Lenovo believes that this product is safe
for use by consumers. These standards and recommendations reflect the consensus of the worldwide
scientific community, and result from deliberations of panels and committees of scientists, who continually
review and interpret the extensive research literature.
In some situations or environments, the use of wireless devices might be restricted by the proprietor of a
building or responsible representatives of an organization. For example, these situations and areas might
include the following:
• 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
identified as harmful.
If you are uncertain of the policy that applies to the use of wireless devices in a specific area (such as an
airport or hospital), you are encouraged to ask for authorization to use a wireless device prior to turning
on the computer.
