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, 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 accessories. 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
