Your computer contains the following types of internal CRUs:
Internal CRUs (located behind an access panel): These CRUs are 
isolated parts within the computer that are concealed by an access panel 
that is typically secured by either one or two screws. Once the access 
panel is removed, only the specific CRU is visible. Examples of these 
types of CRUs include memory modules and hard disk drives.
Internal CRUs (located within the product): These CRUs are accessible 
only by opening the computer ’s outer case. Examples of these CRUs 
include PCI Express Mini Cards and the integrated keyboard.

„Wireless interoperability
Wireless LAN PCI Express Mini Card is designed to be interoperable with 
any wireless LAN product that is based on Direct Sequence Spread 
Spectrum (DSSS), Complementary Code Keying (CCK), and/or 
Orthogonal Frequency Division Multiplexing (OFDM) radio technology, 
and is compliant to:
 The IEEE 802.11a/b/g/n Standard on Wireless LANs, as defined and 
approved by the Institute of Electrical and Electronics Engineers.
 The Wireless Fidelity (WiFi) certification as defined by the Wi-Fi 
Alliance.
„Usage environment and your health
Wireless LAN PCI Express Mini Card emits 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 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  
						

							92
Appendix E. Notices
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 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 prior to turning on the computer.
„Safety information related to Mobile Broadband
1Do 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. 
2Avoid using Mobile Broadband feature outdoors during a 
thunderstorm.  
						

							Appendix E. Notices
93
3Use 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. 
4Follow 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.
5The 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. 
6The 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.
