recommendations reect the consensus of the scientic 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 integrated wireless cards may be restricted by the proprietor
of the building or responsible representatives of the organization. These situations and areas may for
example include:
• Using the integrated wireless cards 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
identied as harmful.
If you are uncertain of the policy that applies to the use of wireless devices in a specic organization (such as
airport or hospital), you are encouraged to ask for authorization to use integrated wireless cards 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 ammable 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.
