Lenovo G450/G550 User Guide V2.0

Appendix E. Notices

 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 far

much less than the electromagnetic energy emitted by wireless devices like for example 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

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.

Avoid using Mobile Broadband feature outdoors during a thunderstorm.

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.

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.

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.
