Vehicles—RF signals may affect improperly installed or inadequately
shielded electronic systems in motor vehicles. Check with 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.
Blasting areas—Turn off your phone where blasting is in progress.
Observe restrictions, and follow any regulations or rules.
Potentially explosive atmospheres—Turn off your phone 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 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
