76 Caring for Your Phone
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
