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
such as 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 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 situations or environments, 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 onboard of airplanes, in hospitals or near petrol stations, blasting
areas (with electro-explosive devices), medical implants or body-worn electronic medical devices.
• 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, you
are encouraged to ask for authorization to use integrated wireless cards prior to turning on the tablet.
