151 Safety
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.
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 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.
Turn off your phone when you are in an area with a
potentially explosive atmosphere. Although it is rare,
