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. Turn off your 
device before boarding an aircraft. The use of wireless teledevices in an 
aircraft may be dangerous to the operation of the aircraft, disrupt the 
wireless telephone network, and may be illegal.
■ Potentially Explosive Environments
Turn 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. Turn 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 manufacturers of vehicles using liquefied petroleum gas (such 
as propane or butane) to determine if this device can be safely used in 
their vicinity.
