Posted Facilities
Switch your mobile device off in any facility where posted
notices require you to do so.
Potentially Explosive Environments
Switch your mobile device off when in any area with a
potentially explosive atmosphere and obey all signs and
instructions. Sparks in such areas could cause an explosion
or fire resulting in bodily injury or even death. Users are
advised to switch the mobile device off while at a refueling
point (service station).
Users are reminded of the need to observe restrictions on the
use of radio equipment in fuel depots (fuel storage and
distribution areas), chemical plants, or where blasting
operations are in progress. Areas with a potentially explosive
atmosphere are often, but not always, clearly marked. They
include below deck on boats, chemical transfer or storage
facilities, vehicles using liquefied petroleum gas (such as
propane or butane), areas where the air contains chemicals
or particles, such as grain, dust, or metal powders, and any
other area where you would normally be advised to turn off
your vehicle engine. Vehicles using liquefied petroleum gas
(such as propane or butane) must comply with the National
Fire Protection Standard (NFPA-58). For a copy of this
standard, contact the National Fire Protection Association.
When your Device is Wet
Do not turn on your device if it is wet. If your device is
already on, turn it off and remove the battery immediately (if
the device will not turn off or you cannot remove the battery,
leave it as-is). Then, dry the device with a towel and take it
to a service center.
FCC Hearing Aid Compatibility (HAC)
Regulations for Wireless Devices
The U.S. Federal Communications Commission (FCC) has
established requirements for digital wireless mobile devices
to be compatible with hearing aids and other assistive
hearing devices.
When individuals employing some assistive hearing devices
(hearing aids and cochlear implants) use wireless mobile
devices, they may detect a buzzing, humming, or whining
noise. Some hearing devices are more immune than others
to this interference noise, and mobile devices also vary in the
amount of interference they generate.
