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.
Always turn off the phone in health care facilities and request
Note:
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.
