ment that could be sensitive to external RF
energy.
Vehicles
RF signals may affect improperly installed
or inadequately shielded electronic
systems in motor vehicles. Check with the
manufacturer or its representative regard-
ing your vehicle. You should also consult
the manufacturer of any equipment that
has been added to your vehicle.
Posted Facilities
Turn your phone OFF in any facility where
posted notices so require.
AIRCRAFT
FCC regulations prohibit using your phone
while in the air.
Switch OFF your phone before boarding
an aircraft.
BLASTING AREAS
To avoid interfering with blasting opera-
tions, turn your phone OFF when in a
“blasting area” or in areas posted “Turn
off two-way radio.” Obey all signs and
instructions.
POTENTIALLY EXPLOSIVE AREAS
Turn your phone OFF when in any area
with a potentially explosive atmosphere
and obey all signs and instructions. Sparks
in such areas could cause an explosion or
fire resulting in bodily injury or even
death. Areas with a potentially explosive
atmosphere are often but not always
clearly marked. They include fueling areas
such as gasoline stations; below deck on
boats; fuel or chemical transfer or storage
facilities; vehicles using liquefied petro-
leum gas (such as propane or butane);
areas where the air contains chemicals or
particles, such as grain, dust, or metal
powders; and any other area where you
would normally be advised to turn off
your vehicle engine.
FOR VEHICLES EQUIPPED WITH
AIR BAGS
An air bag inflates with great force. DO
NOT place objects, including both installed
or portable wireless equipment, in the area
over the air bag or in the air bag deploy-
ment area. If in-vehicle wireless equipment
is improperly installed and the air bag in-
flates, serious injury could result.
The U.S. Food and Drug Admin-

and Radiological Health
Consumer Update on
Mobile Phones
FDA has been receiving inquiries about the
safety of mobile phones, including cellular
phones and PCS phones. The following
summarizes what is known--and what
remains unknown--about whether these
products can pose a hazard to health, and
what can be done to minimize any poten-
tial risk.
Why the concern?
Mobile phones emit low levels of radio
frequency energy (i.e., radio frequency
radiation) in the microwave range while
being used. They also emit very low levels
of radio frequency energy (RF), considered
non-significant, when in the stand-by
mode. It is well known that high levels of
RF can produce biological damage
through heating effects (this is how your
microwave oven is able to cook food).
However, it is not known whether, to what
extent, or through what mechanism,
lower levels of RF might cause adverse
health effects as well. Although some
research has been done to address these
questions, no clear picture of the biologi-
cal effects of this type of radiation has
emerged to date. Thus, the available
science does not allow us to conclude that
mobile phones are absolutely safe, or that
they are unsafe. However, the available
scientific evidence does not
demonstrate
any adverse health effects associated with
the use of mobile phones.
What kinds of phones are in
question?
Questions have been raised about hand-
held mobile phones, the kind that have a
built-in antenna that is positioned close to
the user’s head during normal telephone
conversation. These types of mobile
phones are of concern because of the
short distance between the phone’s
antenna--the primary source of the RF--
and the person’s head. The exposure to RF
from mobile phones in which the antenna
