Usage environment and your health
Wireless LAN PCI Express Mini Card and Bluetooth Daughter Card emit radio frequency
electromagnetic energy like other radio devices. However, the level of energy emitted is much
less than the electromagnetic energy emitted by wireless devices such as mobile phones.
Due to the fact that wireless LAN PCI Express Mini Card and Bluetooth Daughter Card operate
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:
• Using the integrated wireless cards on board of airplanes, or in hospitals
• 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 authorization to use
wireless LAN PCI Express Mini Card or Bluetooth Daughter Card prior to turning on the
computer.

Safety information related to Mobile Broadband
1
Do not use the Mobile Broadband feature on your computer in highly flammable areas (e.g.
gas station) or near blasting. Though it is rare, the Mobile Broadband module, like other
cellular network devices, could generate a spark.
2
Avoid using Mobile Broadband feature outdoors during a thunderstorm.
3
Use of mobile devices on board aircraft is explicitly prohibited by many airlines companies,
especially during take-off and landing. The built-in Mobile Broadband module on your computer
is a low-power radio transceiver. When it is turned on, it intermittently receives and transmits
radio frequency (RF) energy which could cause interference with the operation of the airplane
communication or navigation system. Refer to rules or regulations of your airline company for
Mobile Broadband use. Never enable Mobile Broadband feature on your computer unless you are
explicitly permitted to do so.
4
Follow restrictions when using your computer in hospitals. Some equipments in hospitals are
sophisticated and are susceptible to electromagnetic interference. Do not enable Mobile
Broadband feature near medical equipment without requesting permission.
5
The Mobile Broadband communication may affect the operation of implanted cardiac pacemakers
and other medically implanted equipment. Patients with cardiac pacemakers should be well
aware that use of Mobile Broadband feature on this computer may cause the implanted device to
malfunction. If patients have any doubt that there is interference taking place, immediately
disable the wireless radio on the computer and contact the doctor for more information.
6
The Mobile Broadband module embedded in your computer does not support voice calls,
hence their use for essential communications is not possible. Therefore you should never
rely upon the device for essential communications.
