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 and/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:
ⅷ Fueling areas such as gas stations.
ⅷ Below deck on boats.
Note: Always turn off the phone in health care facilities and request
permission before using the phone near medical equipment.
