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 energy (RF) 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 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 dont 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 phones 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.
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.

What is FDA doing to find out more about the possible 
health effects of wireless phone RF?
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 
energy (RF).
FDA has been a leading participant in the World Health 
Organization international Electromagnetic 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.
FDA and Cellular Telecommunications & Internet Association 
(CTIA) have a formal Cooperative Research and Development 
Agreement (CRADA) to do research on wireless phone safety. 
FDA provides the scientific oversight, obtaining input from 
experts in government, industry, and academic organizations. 
CTIA-funded research is conducted through contracts to 
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.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 
energy (RF). 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 do 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.

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 energy (RF), 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 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.
Do hands-free kits for wireless phones reduce 
risks from exposure to RF emissions?
Since there are no known risks from exposure to RF emissions 
from wireless phones, there is no reason to believe that hands-
free kits reduce risks. Hands-free kits can be used with wireless 
phones for convenience and comfort. These systems reduce the 
absorption of RF energy in the head because the phone, which is the source of the RF emissions, will not be placed against the 
head. On the other hand, if the phone is mounted against the 
waist or other part of the body during use, then that part of the 
body will absorb more RF energy. Wireless phones marketed in 
the U.S. are required to meet safety requirements regardless of 
whether they are used against the head or against the body. 
Either configuration should result in compliance with the safety 
limit.
Do wireless phone accessories that claim to shield 
the head from RF radiation work?
Since there are no known risks from exposure to RF emissions 
from wireless phones, there is no reason to believe that 
accessories that claim to shield the head from those emissions 
reduce risks. Some products that claim to shield the user from RF 
absorption use special phone cases, while others involve nothing 
more than a metallic accessory attached to the phone. Studies 
have shown that these products generally do not work as 
advertised. Unlike hand-free kits, these so-called shields 
may interfere with proper operation of the phone. The phone may 
be forced to boost its power to compensate, leading to an 
increase in RF absorption. In February 2002, the Federal trade 
Commission (FTC) charged two companies that sold devices that 
claimed to protect wireless phone users from radiation with 
making false and unsubstantiated claims. 
u450.book  Page 138  Wednesday, August 19, 2009  6:03 PM 
						

							Health and Safety Information       139
According to FTC, these defendants lacked a reasonable basis to 
substantiate their claim.
What about wireless phone interference with 
medical equipment?
Radio frequency energy (RF) from wireless phones can interact 
with some electronic devices. For this reason, FDA helped 
develop a detailed test method to measure electromagnetic 
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 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. FDA has tested 
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.
FDA continues to monitor the use of wireless phones for possible 
interactions with other medical devices. Should harmful interference be found to occur, FDA will conduct testing to assess 
the interference and work to resolve the problem.

important responsibility accompanies the benefits of wireless 
phones, one that every user must uphold.
When driving a car, driving is your first responsibility. When using 
your wireless phone behind the wheel of a car, practice good 
common sense and remember the following tips:
1.Get to know your wireless phone and its features, such as 
speed dial and redial. If available, these features help you 
to place your call without taking your attention off the road.
2.When available, use a hands-free device. If possible, add 
an additional layer of convenience and safety to your 
wireless phone with one of the many hands free 
accessories available today.
3.Position your wireless phone within easy reach. Be able to 
access your wireless phone without removing your eyes 
from the road. If you get an incoming call at an 
inconvenient time, let your voice mail answer it for you.
4.Let the person you are speaking with know you are driving; 
if necessary, suspend the call in heavy traffic or hazardous 
weather conditions. Rain, sleet, snow, ice and even heavy 
traffic can be hazardous.
5.Do not take notes or look up phone numbers while driving. 
Jotting down a to do list or flipping through your address 
book takes attention away from your primary 
responsibility, driving safely.
6.Dial sensibly and assess the traffic; if possible, place calls 
when you are not moving or before pulling into traffic. Try 
to plan calls when your car will be stationary. If you need to 
make a call while moving, dial only a few numbers, check 
the road and your mirrors, then continue.
7.Do not engage in stressful or emotional conversations that 
may be distracting. Make people you are talking with 
aware you are driving and suspend conversations that 
have the potential to divert your attention from the road.
8.Use your wireless phone to call for help. Dial 9-1-1 or other 
local emergency number in the case of fire, traffic accident 
or medical emergencies. 
u450.book  Page 140  Wednesday, August 19, 2009  6:03 PM 
						

							Health and Safety Information       141 9.
Use your wireless phone to help others in emergencies. If 
you see an auto accident, crime in progress or other 
serious emergency where lives are in danger, call 9-1-1 or 
other local emergency number, as you would want others 
to do for you.
10.Call roadside assistance or a special non-emergency 
wireless assistance number when necessary. If you see a 
broken-down vehicle posing no serious hazard, a broken 
traffic signal, a minor traffic accident where no one 
appears injured, or a vehicle you know to be stolen, call 
roadside assistance or other special non-emergency 
number.
The wireless industry reminds you to use your phone safely when 
driving.

Responsible Listening
Caution!: Avoid potential hearing loss.
Damage to hearing occurs when a person is exposed to loud 
sounds over time. The risk of hearing loss increases as sound is 
played louder and for longer durations. Prolonged exposure to 
loud sounds (including music) is the most common cause of 
preventable hearing loss. Some scientific research suggests that 
using portable audio devices, such as portable music players and 
cellular telephones, at high volume settings for long durations 
may lead to permanent noise-induced hearing loss. This includes 
the use of headphones (including headsets, earbuds, and 
Bluetooth or other wireless devices). Exposure to very loud sound 
has also been associated in some studies with tinnitus (a ringing 
in the ear), hypersensitivity to sound and distorted hearing.
Individual susceptibility to noise-induced hearing loss and 
potential hearing problem varies. Additionally, the amount of 
sound produced by a portable audio device varies depending on 
the nature of the sound, the device settings, and the headphones 
that are used. As a result, there is no single volume setting that is 
appropriate for everyone or for every combination of sound, 
settings and equipment. 
You should follow some commonsense recommendations when 
using any portable audio device:
u450.book  Page 141  Wednesday, August 19, 2009  6:03 PM 
						

							142
Set the volume in a quiet environment and select the lowest volume at 
which you can hear adequately.
When using headphones, turn the volume down if you cannot hear the 
people speaking near you or if the person sitting next to you can hear 
what you are listening to.
Do not turn the volume up to block out noisy surroundings. If you 
choose to listen to your portable device in a noisy environment, use 
noise-cancelling headphones to block out background environmental 
noise. By blocking background environment noise, noise cancelling 
headphones should allow you to hear the music at lower volumes than 
when using earbuds.
Limit the amount of time you listen. As the volume increases, less time 
is required before you hearing could be affected.
Avoid using headphones after exposure to extremely loud noises, such 
as rock concerts, that might cause temporary hearing loss. Temporary 
hearing loss might cause unsafe volumes to sound normal.
Do not listen at any volume that causes you discomfort. If you 
experience ringing in your ears, hear muffled speech or experience 
any temporary hearing difficulty after listening to your portable audio 
device, discontinue use and consult your doctor.

Operating Environment
Remember to follow any special regulations in force in any area 
and always switch your phone off whenever it is forbidden to use 
it, or when it may cause interference or danger. 
When connecting the phone or any accessory to another device, 
read its users guide for detailed safety instructions. Do not 
connect incompatible products.As with other mobile radio transmitting equipment, users are 
advised that for the satisfactory operation of the equipment and 
for the safety of personnel, it is recommended that the 
equipment should only be used in the normal operating position 
(held to your ear with the antenna pointing over your shoulder if 
you are using an external antenna).
Using Your Phone Near Other Electronic Devices
Most modern electronic equipment is shielded from radio 
frequency (RF) signals. However, certain electronic equipment 
may not be shielded against the RF signals from your wireless 
phone. Consult the manufacturer to discuss alternatives.
Implantable Medical Devices
A minimum separation of six (6) inches should be maintained 
between a handheld wireless phone and an implantable medical 
device, such as a pacemaker or implantable cardioverter 
defibrillator, to avoid potential interference with the device.
Persons who have
 such devices:
Should ALWAYS keep the phone more than six (6) inches from their 
implantable medical device when the phone is turned ON;
Should not carry the phone in a breast pocket;
Should use the ear opposite the implantable medical device to 
minimize the potential for interference;

FCC Hearing-Aid Compatibility (HAC) 
Regulations for Wireless Devices
On July 10, 2003, the U.S. Federal Communications Commission 
(FCC) Report and Order in WT Docket 01-309 modified the 
exception of wireless phones under the Hearing Aid Compatibility 
Act of 1988 (HAC Act) to require digital wireless phones be 
compatible with hearing-aids. 
The intent of the HAC Act is to ensure reasonable access to 
telecommunications services for persons with hearing 
disabilities. 
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 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 users 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 
u450.book  Page 144  Wednesday, August 19, 2009  6:03 PM 
						

							Health and Safety Information       145
is considered acceptable for normal use. A sum of 6 is 
considered for best use.
 
In the above example, if a hearing aid meets the M2 level rating 
and the wireless phone meets the M3 level rating, the sum of the 
two values equal M5. This is synonymous for T ratings. This 
should provide the hearing aid user with normal usage while 
using their hearing aid with the particular wireless phone. 
Normal usage in this context is defined as a signal quality that 
is acceptable for normal operation. 
The M mark is intended to be synonymous with the U mark. The 
T mark is intended to be synonymous with the UT mark. The M 
and T marks are recommended by the Alliance for 
Telecommunications Industries Solutions (ATIS). The U and UT 
marks are referenced in Section 20.19 of the FCC Rules. The HAC rating and measurement procedure are described in the 
American National Standards Institute (ANSI) C63.19 standard.
Other Medical Devices
If you use any other personal medical devices, consult the 
manufacturer of your device to determine if it is adequately 
shielded from external RF energy. Your physician may be able to 
assist you in obtaining this information. Switch 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 be 
using equipment 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 regarding your vehicle. You 
should also consult the manufacturer of any equipment that has 
been added to your vehicle.
Posted Facilities
Switch your phone off in any facility where posted notices require 
you to do so.
Potentially Explosive Environments
Switch your phone off when in any area with a potentially 
explosive atmosphere and obey all signs and instructions. Sparks 
M3                 +                    M2         =     5T3                 +                    T2         =     5
