Chapter 6. Safety, use, and care information
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.
