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 off your phone when in a
blasting area or in other areas with signs indicating that two-way radios should
be turned off. Construction crews often use remote-control RF devices to set
off explosives.
