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 
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 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

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, vehicles using liquefied 
petroleum gas (such as propane or butane), and areas where the air contains 
chemicals or particles such as grain, dust or metal powders. Do not switch the 
notebook on when wireless phone use is prohibited or when it may cause 
interference or danger.

Emergency calls

Warning: You cannot make emergency calls through this device. To make an 
emergency call you shall dial out through your mobile phone or other 
telephone call system.
