Other medical devices
If you use any other personal medical device, consult the manufacturer of your device to
determine if it is adequately shielded from RF energy. Your physician may be able to assist you in
obtaining this information.
Turn your phone off in health care facilities when any regulations posted in these areas instruct
you to do so. Hospitals or healthcare facilities may be using equipment that could be sensitive
to RF energy.
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.
Posted facilities
Turn your phone off in any facility where posted notices so require.
Aircraft
FCC regulations prohibit using your phone while in the air. Switch off your phone before
boarding an aircraft.
Blasting areas
To avoid interfering with blasting operations, turn your phone off when 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 in any area with a potentially explosive atmosphere and 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; fuel or chemical transfer or
storage facilities; 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; and any
other area where you would normally be advised to turn off your vehicle engine.
