Maintaining Safe Use of and Access
to Your Phone
Do Not Rely on Your Phone for Emergency Calls
Mobile phones operate using radio signals, which cannot guarantee
connection in all conditions. Therefore you should never rely solely upon
any mobile phone for essential communication (e.g., medical
emergencies). Emergency calls may not be possible on all cellular networks
or when certain network services or mobile phone features are in use.
Check with your local service provider for details.
Using Your Phone While Driving
Talking on your phone while driving (or operating the phone without a
hands-free device) is prohibited in some jurisdictions. Laws vary as to
specific restrictions. Remember that safety always comes first.
Following Safety Guidelines
To operate your phone safely and efficiently, always follow any special
regulations in a given area. Turn your phone off in areas where use is
forbidden or when it may cause interference or danger.
Using Your Phone Near Other Electronic Devices
Most modern electronic equipment is shielded from radio frequency (RF)
signals. However, RF signals from wireless phones may affect inadequately
shielded electronic equipment.
RF signals may affect improperly installed or inadequately shielded
electronic operating systems or entertainment systems in motor vehicles.
Check with the manufacturer or their representative to determine if these
systems are adequately shielded from external RF signals. Also check with
the manufacturer regarding any equipment that has been added to your
vehicle.
Consult the manufacturer of any personal medical devices, such as
pacemakers and hearing aids, to determine if they are adequately shielded
from external RF signals.
Turning Off Your Phone Before Flying
Turn off your phone before boarding any aircraft. To prevent possible
interference with aircraft systems, the U.S. Federal Aviation Administration
(FAA) regulations require you to have permission from a crew member to
use your phone while the plane is on the ground. To prevent any risk of
interference, FCC regulations prohibit using your phone while the plane is
in the air.
Turning Off Your Phone in Dangerous Areas
To avoid interfering with blasting operations, turn your phone off when in a
blasting area or in other areas with signs indicating two-way radios should
be turned off. Construction crews often use remote-control RF devices to
set off explosives.
Turn your phone off when you’re in any area that has a potentially explosive
atmosphere. Although it’s rare, your phone and accessories could generate
sparks. Sparks can cause an explosion or fire, resulting in bodily injury or
even death. These areas are often, but not always, clearly marked. They
include:
Ⅲ Fueling areas such as gas stations.
Note
Always turn off the phone in healthcare facilities, and request
permission before using the phone near medical equipment.
