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, 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 an 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.
Airplanes
Using your device while flying may be 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 refuelling 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.
