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.
