Pacemakers. Pacemaker manufacturers recommend that a minimum separation
of 15.3 centimeters (6 inches) be maintained between wireless devices and a
pacemaker to avoid potential interference with the pacemaker. These
recommendations are consistent with the independent research by and
recommendations of Wireless Technology Research. Persons with pacemakers
should do the following:
• Always keep the device more than 15.3 centimeters (6 inches) from the
pacemaker
• Not carry the device near your pacemaker when the device is switched o. If
you suspect interference, switch off your device, and move it
.
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
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.
