Vehicles
RF signals may affect improperly installed or inadequately shielded electronic systems
in motor vehicles such as electronic fuel injection systems, electronic antiskid (antilock)
braking systems, electronic speed control systems, and air bag systems. For more
information, check with the manufacturer or its representative of your vehicle or any
equipment that has been added.
Only qualified personnel should service the device, or install the device in a vehicle. Faulty
installation or service may be dangerous and may invalidate any warranty that may apply
to the device. Check regularly that all wireless device equipment in your vehicle is
mounted and operating properly. Do not store or carry flammable liquids, gases, or
explosive materials in the same compartment as the device, its parts, or enhancements.
For vehicles equipped with an air bag, remember that air bags inflate with great force. Do
not place objects, including installed or portable wireless equipment in the area over the
air bag or in the air bag deployment area. If in-vehicle wireless equipment is improperly
installed and the air bag inflates, serious injury could result.
Using your device while flying in aircraft is prohibited. Switch off your device before
boarding an aircraft. The use of wireless devices in an aircraft may be dangerous to the
operation of the aircraft, disrupt the wireless telephone network, and may be illegal.

Potentially explosive environments
Switch off your device when in any area with a potentially explosive atmosphere and
obey all signs and instructions. Potentially explosive atmospheres include areas where
you would normally be advised to turn off your vehicle engine. Sparks in such areas
could cause an explosion or fire resulting in bodily injury or even death. Switch off the
device at refueling points such as near gas pumps at service stations. Observe restrictions
on the use of radio equipment in fuel depots, storage, and distribution areas; chemical
plants; or where blasting operations are in progress. Areas with a potentially explosive
atmosphere are often but not always clearly marked. They include below deck on boats,
chemical transfer or storage facilities and areas where the air contains chemicals or
particles such as grain, dust, or metal powders. You should check with the
