Following Safety Guidelines
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

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.

with aircraft systems, the U.S. Federal Aviation Administration (FAA) regulations

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

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

atmosphere. Although it is rare, your phone or its accessories could
generate sparks. Sparks could cause an explosion or a fire resulting in
