Usage guidelines: All about performance and safety 127
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 of even death.
Areas with a potentially explosive atmosphere are often but
not always clearly marked. They include fueling areas such
as gasoline stations; below deck on boats; fuel or chemical
transfer or storage facilities; vehicles using liguefied
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.
For vehicles equipped with an airbag
An airbag inflates with great force. DO NOT place objects,
including both installed or portable wireless equipment, in the
area over the air bag deployment area. If in-vehicle wireless
equipment is improperly installed and the air bag inflates,
serious injury could result.
