For Your  Safety
Health Care FacilitiesTurn your phone OFF in health care facilities when any regulations posted in 
these areas instruct you to do so. Hospitals or health care facilities may use 
equipment that could be sensitive to external RF energy.
VehiclesRF signals may affect improperly installed or inadequately shielded electronic 
systems in motor vehicles. Check with the manufacturer or its representative 
regarding your vehicle.  You should also consult the manufacturer of any 
equipment that has been added to your vehicle.
Posted FacilitiesTurn your phone OFF in any facility where posted notices so require.
AircraftFCC regulations prohibit using your phone while in the air. Switch OFF your 
phone before boarding an aircraft.
Blasting AreasTo avoid interfering with blasting operations, 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 AtmosphereTurn 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 marked 
clearly. Potential areas may include: fueling areas (such as gasoline stations); 
below deck on boats; fuel or chemical transfer or storage facilities; vehicles 
using liquefied petroleum 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 an Air BagAn air bag inflates with great force. DO NOT place objects, including either 
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.
FDA Consumer Update
  The U.S. Food and Drug Administration’s Center for Devices and 
Radiological Health Consumer Update on Mobile Phones:
1.  Do wireless phones pose a health hazard?The available scientific evidence does not show that any health problems are 
associated with using wireless phones. There is no proof, however, that wireless 
phones are absolutely safe. Wireless phones emit low levels of Radio Frequency 
(RF) energy in the microwave range while being used. They also emit very low 
levels of RF when in idle mode. Whereas high levels of RF can produce health 
effects (by heating tissue), exposure to low level RF that does not produce 
heating effects causes no known adverse health effects. Many studies of low 
level RF exposures have not found any biological effects. Some studies have 
suggested that some biological effects may occur, but such findings have not 
been confirmed by additional research. In some cases, other researchers have 
had difficulty in reproducing those studies, or in determining the reasons for 
inconsistent results.
2.  What is the FDA’s role concerning the safety of wireless 
phones?
Under the law, the FDA does not review the safety of radiation-emitting 
consumer products such as wireless phones before they can be sold, as it does 
with new drugs or medical devices. However, the agency has authority to take 
action if wireless phones are shown to emit Radio Frequency (RF) energy at a 
level that is hazardous to the user. In such a case, the FDA could require the 
manufacturers of wireless phones to notify users of the health hazard and to 
repair, replace, or recall the phones so that the hazard no longer exists. 
						

							132
For Your  Safety
Although the existing scientific data does not justify FDA regulatory actions, 
the FDA has urged the wireless phone industry to take a number of steps, 
including the following:
• Support needed research into possible biological effects of RF of the type 
emitted by wireless phones;
• Design wireless phones in a way that minimizes any RF exposure to the user 
that is not necessary for device function; and
• Cooperate in providing users of wireless phones with the best possible 
information on possible effects of wireless phone use on human health.
The FDA belongs to an interagency working group of the federal agencies that 
have responsibility for different aspects of RF safety to ensure coordinated 
efforts at the federal level. The following agencies belong to this working group:
• National Institute for Occupational Safety and Health• Environmental Protection Agency• Occupational Safety and Health Administration• National Telecommunications and Information Administration
The National Institutes of Health participates in some interagency working 
group activities, as well.
The FDA shares regulatory responsibilities for wireless phones with the Federal 
Communications Commission (FCC). All phones that are sold in the United 
States must comply with FCC safety guidelines that limit RF exposure. The 
FCC relies on the FDA and other health agencies for safety questions about 
wireless phones.
The FCC also regulates the base stations that the wireless phone networks 
rely upon. While these base stations operate at higher power than do the 
wireless phones themselves, the RF exposures that people get from these base 
stations are typically thousands of times lower than those they can get from 
wireless phones. Base stations are thus not the subject of the safety questions 
discussed in this document.
3.  What kinds of phones are the subject of this update?The term “wireless phone” refers here to handheld wireless phones with built-in 
antennas, often called “cell”, “mobile”, or “PCS” phones. These types of wireless  
						

							133
phones can expose the user to measurable Radio Frequency (RF) energy 
because of the short distance between the phone and the user’s head. 
These RF exposures are limited by FCC safety guidelines that were developed 
with the advice of the FDA and other federal health and safety agencies. 
When the phone is located at greater distances from the user, the exposure 
to RF is drastically lower because a person’s RF exposure decreases rapidly 
with increasing distance from the source. The so-called “cordless phones,” 
which have a base unit connected to the telephone wiring in a house, typically 
operate at far lower power levels, and thus produce RF exposures far below the 
FCC safety limits.
4.  What are the results of the research done already?The research done thus far has produced conflicting results, and many studies 
have suffered from flaws in their research methods. Animal experiments 
investigating the effects of Radio Frequency (RF) energy exposures 
characteristic of wireless phones have yielded conflicting results that often 
cannot be repeated in other laboratories. A few animal studies, however, have 
suggested that low levels of RF could accelerate the development of cancer in 
laboratory animals. However, many of the studies that showed increased tumor 
development used animals that had been genetically engineered or treated 
with cancer-causing chemicals so as to be pre-disposed to develop cancer in 
the absence of RF exposure. Other studies exposed the animals to RF for up 
to 22 hours per day. These conditions are not similar to the conditions under 
which people use wireless phones, so we do not know with certainty what the 
results of such studies mean for human health. Three large epidemiology 
studies have been published since December 2000. Between them, the 
studies investigated any possible association between the use of wireless 
phones and primary brain cancer, glioma, meningioma, or acoustic neuroma, 
tumors of the brain or salivary gland, leukemia, or other cancers. None of the 
studies demonstrated the existence of any harmful health effects from wireless 
phone RF exposures. However, none of the studies can answer questions about 
long-term exposures, since the average period of phone use in these studies 
was around three years. 
						

							134
For Your  Safety
5.  What research is needed to decide whether RF exposure from 
wireless phones poses a health risk?
A combination of laboratory studies and epidemiological studies of people 
actually using wireless phones would provide some of the data that are needed. 
Lifetime animal exposure studies could be completed in a few years. However, 
very large numbers of animals would be needed to provide reliable proof of a 
cancer promoting effect if one exists. Epidemiological studies can provide data 
that is directly applicable to human populations, but ten or more years follow-
up may be needed to provide answers about some health effects, such as 
cancer. This is because the interval between the time of exposure to a cancer-
causing agent and the time tumors develop — if they do — may be many, 
many years. The interpretation of epidemiological studies is hampered by 
difficulties in measuring actual RF exposure during day-to-day use of wireless 
phones. Many factors affect this measurement, such as the angle at which the 
phone is held, or which model of phone is used.
6.  What is the FDA doing to find out more about the possible 
health effects of wireless phone RF?
The FDA is working with the U.S. National Toxicology Program and with groups 
of investigators around the world to ensure that high priority animal studies are 
conducted to address important questions about the effects of exposure to 
Radio Frequency (RF) energy. 
The FDA has been a leading participant in the World Health Organization 
International Electro Magnetic Fields (EMF) Project since its inception in 1996. 
An influential result of this work has been the development of a detailed 
agenda of research needs that has driven the establishment of new research 
programs around the world. The project has also helped develop a series of 
public information documents on EMF issues. 
The FDA and the Cellular Telecommunications & Internet Association (CTIA) 
have a formal Cooperative Research And Development Agreement (CRADA) 
to do research on wireless phone safety. The FDA provides the scientific 
oversight, obtaining input from experts in government, industry, and academic 
organizations. CTIA-funded research is conducted through contracts with  
						

							135
independent investigators. The initial research will include both laboratory 
studies and studies of wireless phone users. The CRADA will also include a 
broad assessment of additional research needs in the context of the latest 
research developments around the world.
7.   How can I find out how much Radio Frequency energy 
exposure I can get by using my wireless phone?
All phones sold in the United States must comply with Federal 
Communications Commission (FCC) guidelines that limit Radio Frequency (RF) 
energy exposures. The FCC established these guidelines in consultation with 
the FDA and the other federal health and safety agencies. The FCC limit for 
RF exposure from wireless phones is set at a Specific Absorption Rate (SAR) 
of 1.6 watts per kilogram (1.6 W/kg). The FCC limit is consistent with the safety 
standards developed by the Institute of Electrical and Electronic Engineering 
(IEEE) and the National Council on Radiation Protection and Measurement. 
The exposure limit takes into consideration the body’s ability to remove heat 
from the tissues that absorb energy from the wireless phone and is set well 
below levels known to have effects. Manufacturers of wireless phones must 
report the RF exposure level for each model of phone to the FCC. The FCC 
website (http://www.fcc.gov/oet/rfsafety) gives directions for locating the FCC 
identification number on your phone so you can find your phone’s RF exposure 
level in the online listing.
8.  What has the FDA done to measure the Radio Frequency 
energy coming from wireless phones?
The Institute of Electrical and Electronic Engineers (IEEE) is developing a 
technical standard for measuring the Radio Frequency (RF) energy exposure 
from wireless phones and other wireless handsets with the participation and 
leadership of FDA scientists and engineers. The standard, “Recommended 
Practice for Determining the Spatial-Peak Specific Absorption Rate (SAR) 
in the Human Body Due to Wireless Communications Devices: Experimental 
Techniques”, sets forth the first consistent test methodology for measuring the 
rate at which RF is deposited in the heads of wireless phone users. The test 
method uses a tissue-simulating model of the human head. Standardized  
						

							136
For Your  Safety
SAR test methodology is expected to greatly improve the consistency of 
measurements made at different laboratories on the same phone. SAR is the 
measurement of the amount of energy absorbed in tissue, either by the whole 
body or a small part of the body. It is measured in watts/kg (or milliwatts/g) 
of matter. This measurement is used to determine whether a wireless phone 
complies with safety guidelines. 
9.  What steps can I take to reduce my exposure to Radio 
Frequency energy from my wireless phone?
If there is a risk from these products — and at this point we do not know 
that there is — it is probably very small. But if you are concerned about 
avoiding even potential risks, you can take a few simple steps to minimize 
your exposure to Radio Frequency (RF) energy. Since time is a key factor in 
how much exposure a person receives, reducing the amount of time spent 
using a wireless phone will reduce RF exposure. If you must conduct extended 
conversations by wireless phone every day, you could place more distance 
between your body and the source of the RF, since the exposure level drops 
off dramatically with distance. For example, you could use a headset and carry 
the wireless phone away from your body or use a wireless phone connected to 
a remote antenna. Again, the scientific data does not demonstrate that wireless 
phones are harmful. But if you are concerned about the RF exposure from 
these products, you can use measures like those described above to reduce 
your RF exposure from wireless phone use.
10.  What about children using wireless phones?The scientific evidence does not show a danger to users of wireless phones, 
including children and teenagers. If you want to take steps to lower exposure 
to Radio Frequency (RF) energy, the measures described above would apply to 
children and teenagers using wireless phones. Reducing the time of wireless 
phone use and increasing the distance between the user and the RF source 
will reduce RF exposure. 
Some groups sponsored by other national governments have advised that  
						

							137
children be discouraged from using wireless phones at all. For example, 
the government in the United Kingdom distributed leaflets containing 
such a recommendation in December 2000. They noted that no evidence 
exists that using a wireless phone causes brain tumors or other ill effects. 
Their recommendation to limit wireless phone use by children was strictly 
precautionary; it was not based on scientific evidence that any health hazard 
exists.
11.  What about wireless phone interference with medical 
equipment?
Radio Frequency (RF) energy from wireless phones can interact with some 
electronic devices. For this reason, the FDA helped develop a detailed test 
method to measure Electro Magnetic Interference (EMI) of implanted cardiac 
pacemakers and defibrillators from wireless telephones. This test method is 
now part of a standard sponsored by the Association for the Advancement 
of Medical Instrumentation (AAMI). The final draft, a joint effort by the FDA, 
medical device manufacturers, and many other groups, was completed in 
late 2000. This standard will allow manufacturers to ensure that cardiac 
pacemakers and defibrillators are safe from wireless phone EMI.
The FDA has tested hearing aids for interference from handheld wireless 
phones and helped develop a voluntary standard sponsored by the Institute 
of Electrical and Electronic Engineers (IEEE). This standard specifies test 
methods and performance requirements for hearing aids and wireless phones 
so that no interference occurs when a person uses a “compatible” phone and a 
“compatible” hearing aid at the same time. This standard was approved by the 
IEEE in 2000. 
The FDA continues to monitor the use of wireless phones for possible 
interactions with other medical devices. Should harmful interference be found 
to occur, the FDA will conduct testing to assess the interference and work to 
resolve the problem.

Driving
Check the laws and regulations on the use of wireless phones in the areas 
where you drive and always obey them. Also, if using your phone while driving, 
please observe the following:
• Give full attention to driving -- driving safely is your first responsibility;• Use hands-free operation, if available;• Pull off the road and park before making or answering a call if driving 
conditions or the law require it.
HAC statement This phone has been tested and rated for use with hearing aids for some of the 
wireless technologies that it uses. 
However, there may be some newer wireless technologies used in this phone 
that have not been tested yet for use with hearing aids. 
It is important to try the different features of this phone thoroughly and in 
different locations, using your hearing aid or cochlear implant, to determine if 
you hear any interfering noise. 
Consult your service provider or the manufacturer of this phone for information 
on hearing aid compatibility. 
If you have questions about return or exchange policies, consult your service 
provider or phone retailer.

FCC Hearing-Aid Compatibility (HAC) Regulations for Wireless 
Devices
While some wireless phones are used near some hearing devices (hearing 
aids and cochlear implants), users may detect a buzzing, humming, or whining 
noise. Some hearing devices are more immune than others to this interference 
noise, and phones also vary in the amount of interference they generate.
The wireless telephone industry has developed a rating system for wireless 
phones, to assist hearing device users to find phones that may be compatible 
with their hearing devices. Not all phones have been rated. Phones that are 
rated have the rating on their box or a label located on the box.
The ratings are not guarantees.
Results will vary depending on the user’s hearing device and hearing loss. If 
your hearing device happens to be vulnerable to interference, you may not be 
able to use a rated phone successfully.
Trying out the phone with your hearing device is the best way to evaluate it for 
your personal needs.
M-Ratings: Phones rated M3 or M4 meet FCC requirements and are likely to 
generate less interference to hearing devices than phones that are not labeled. 
M4 is the better/higher of the two ratings.
T-Ratings: Phones rated T3 or T4 meet FCC requirements and are likely to 
generate less interference to hearing devices than phones that are not labeled. 
T4 is the better/higher of the two ratings.
Hearing devices may also be rated. Your hearing device manufacturer or 
hearing health professional may help you find this rating. Higher ratings mean 
that the hearing device is relatively immune to interference noise. The hearing 
aid and wireless phone rating values are then added together. A sum of 5 is 
considered acceptable for normal use.
A sum of 6 is considered for best use.
