Using Your Phone Near Other Electronic Devices
Most modern electronic equipment is shielded from radiofrequency (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.
Note: Always turn off the phone in health care facilities and request permission before using the phone
near medical equipment.
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:
Fueling areas such as gas stations.
Below deck on boats.
Fuel or chemical transfer or storage facilities.
