HEARING AIDS
Some digital wireless devices may interfere with some hearing aids. If interference
occurs, consult your service provider.
■ 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, 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.
FCC regulations prohibit using your wireless device while in the air. The use of
wireless telephones 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.
Failure to observe these instructions may lead to suspension or denial of telephone
services to the offender, legal action, or both.
