General Safety Tips
For safe operation, please observe the following guidelines.
For additional details, refer to your phone manufacturer's Owner's Manual.
Electronic Devices 
Most electronic equipment, for example in hospitals and motor vehicles, is
shielded from the low-level Radio Frequency (RF) energy that is emitted by your
phone. However, RF energy may affect some malfunctioning or improperly
shielded electronic equipment.
Vehicle Electronic Equipment 
Check with your vehicle manufacturer's representative to determine if all electronic
equipment in your car is adequately shielded from the RF energy emitted from
your phone.
Medical Electronic Equipment
Consult the manufacturer of any personal medical devices you may have (such
as pacemakers, hearing aids, etc.) to determine if they are adequately shielded
from external RF energy. Turn your phone OFF in health care facilities when any
regulations posted in the area instruct you to do so. Hospitals or health care
facilities may be using RF monitoring equipment.
Aircraft
Turn your phone OFF before boarding any aircraft. To prevent possible
interference with aircraft systems, 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 interference with wireless systems,
local RF regulations prohibit using your phone while airborne. Use it on the ground
only with crew permission. Do not use it in the air.
Safety Standards Compliance 
This phone complies with all applicable RF safety standards and
recommendations for the protection of public exposure to RF electromagnetic
