■ 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.
