•Follow the manufacturer directions for the implanted
medical device.
If you have any questions about using your wireless device
with an implanted medical device, consult your health
care provider.

Hearing aids

Some digital wireless devices may interfere with some
hearing aids.
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 explosiveenvironments
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
and areas 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.
