Vehicles
RF signals may affect improperly installed or inadequately shielded electronic systems in motor vehicles such as electronic fuel
injection, electronic antilock braking, electronic speed control, and air bag systems. For more information, check with the
manufacturer of your vehicle or its equipment.
Only qualified personnel should service the device or install the device in a vehicle. Faulty installation or service may be
dangerous and may invalidate your warranty. 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 accessories. Remember that air bags inflate with great force. Do not place your device or accessories in the
air bag deployment area.
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 and may be illegal.
Potentially explosive environments
Switch off your device in any area with a potentially explosive atmosphere. Obey all posted instructions. Sparks in such areas
could cause an explosion or fire resulting in bodily injury or death. Switch off the device at refuelling points such as near gas
pumps at service stations. Observe restrictions 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
areas where you would be advised to turn off your vehicle engine, below deck on boats, chemical transfer or storage facilities
and 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.
