Turning Off Your Phone Before Flying
Turn off your phone before boarding any aircraft. To prevent possible
interference with aircraft systems, the U.S. Federal Aviation
Administration (FAA) regulations require you to have permission
from a crew member to use your phone while the plane is on the
ground. To prevent any risk of interference, FCC regulations prohibit
using your phone while the plane is in the air.
Turning Off Your Phone in Dangerous Areas
To avoid interfering with blasting operations, turn off your phone
when in a blasting area or in other areas with signs indicating that
two-way radios should be turned off. Construction crews often use
remote-control RF devices to set off explosives.
Turn off your phone when you’re in any area that has a potentially
explosive atmosphere. Although it’s rare, your phone or its
accessories could generate sparks. Sparks could cause an explosion
or a fire resulting in bodily injury or even death. These areas 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.
ᮣ 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’s engine.
Note: Never transport or store flammable gas, liquid, or explosives in the
compartment of your vehicle that contains your phone or accessories.
Restricting Children’s Access to your Phone
Your PCS Phone is not a toy. Children should not be allowed to play
with it because they could hurt themselves and others, damage the
phone or make calls that increase your phone bill.
