Section 4: Safety Guidelines and Warranty Information
4A: Safety 116
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,
just 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.
