Safety information
Medical devices
Pacemakers—If your portable wireless phone is too close to a pacemaker, the phone’s RF energy
may interfere with the pacemaker’s operation. The Health Industry Manufacturers Association
and the wireless technology research community recommend that you follow these guidelines to
minimize the potential for interference.
■ Always keep the phone at least six inches (15 centimeters) away from your pacemaker when
the phone is turned on.
■ Do not carry your phone near your heart.
■ Use the ear opposite the pacemaker.
■ If you have any reason to suspect that interference is taking place, turn off your phone
immediately.
Hearing aids—Some digital wireless phones may interfere with hearing aids. In the event of such
interference, you may want to consult your service provider or call the customer service line to
discuss alternatives.
Other medical devices—If you use any other personal medical device, consult the manufacturer of
the device to determine if it is adequately shielded from external RF energy. Your physician may
be able to help you obtain this information.
In health care facilities—Turn your phone off in health care facilities when instructed. Hospitals and
health care facilities may be using equipment that is sensitive to external RF energy.
Avoiding potentially unsafe areas
Posted facilities—Turn your phone off in any facility when posted notices require you to do so.
Aircraft—FCC regulations prohibit using your phone on a plane that is in the air. Turn your phone
off before boarding aircraft.
Vehicles—RF signals may affect improperly installed or inadequately shielded electronic systems
in motor vehicles. Check with the manufacturer or its representative regarding your vehicle.
You should also consult the manufacturer of any equipment that has been added to your vehicle.
Blasting areas—To avoid interfering with blasting operations, turn your phone off when you are in
a blasting area or in areas posted “Turn off two-way radio.” Obey all signs and instructions.
Potentially explosive atmospheres—Turn your phone off when you are in any area with a potentially
explosive atmosphere. Obey all signs and instructions. Sparks in such areas could cause an
explosion or fire resulting in bodily injury or even death.
Areas with a potentially explosive atmosphere are often, but not always, clearly marked.
They include
■ Fueling areas such as gas stations
■ Below deck on boats
■ Transfer or storage facilities for fuel or chemicals
■ Vehicles using liquefied petroleum gas, such as propane or butane
■ Areas where the air contains chemicals or particles such as grain, dust, or metal powders
■ Any other area where you would normally be advised to turn off your vehicle engine
