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.
Knowing Performance and Safety Guidelines
Note:
Always turn off the phone
in health care facilities
and request permission
before using the phone
near medical equipment.
