3.  What kinds of phones are the subject of this update?
The term ‘wireless phone’ refers here to handheld wireless phones with builtin 
antennas, often called ‘cell’, ‘mobile’, or ‘PCS’ phones. These types of wireless phones 
can expose the user to measurable radiofrequency energy (RF) 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 radiofrequency 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 predisposed 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 don’t 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. 
						

							22
However, none of the studies can answer questions about longterm exposures, since 
the average period of phone use in these studies was around three years.
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 is 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 10 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 radiofrequency 
energy (RF). The 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. 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 
Safety Guidelines 
						

							23
input from experts in government, industry, and academic organizations. CTIA funded 
research is conducted through contracts with 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 radiofrequency 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 radiofrequency energy (RF) 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 telephones 
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 radiofrequency energy coming from 
wireless phones?
The Institute of Electrical and Electronic Engineers (IEEE) is developing a technical 
standard for measuring the radiofrequency energy (RF) 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  
						

							24
test method uses a tissuesimulating model of the human head. Standardized 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 radiofrequency 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 radiofrequency 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 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 radiofrequency 
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 
Safety Guidelines 
						

							25
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?
Radiofrequency energy (RF) from wireless phones can interact with some electronic 
devices. For this reason, the 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 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.

10 Driver Safety Tips
Your wireless phone gives you the powerful ability to communicate by voice almost 
anywhere, anytime. An important responsibility accompanies the benefits of wireless 
phones, one that every user must uphold. When operating 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. 
Carefully read your instruction manual and learn to take advantage of valuable 
features most phones offer, including automatic redial and memory. Also, work to 
memorize the phone keypad so you can use the speed dial function without taking 
your attention off the road.
2.  When available, use a handsfree device. A number of handsfree wireless phone 
accessories are readily available today. Whether you choose an installed mounted 
device for your wireless phone or a speaker phone accessory, take advantage of 
these devices if available to you.
3.  Position your wireless phone within easy reach. Make sure you place your wireless 
phone within easy reach and where you can reach it without removing your eyes 
from the road. If you get an incoming call at an inconvenient time, if possible, let your 
voicemail answer it for you.
Safety Guidelines

4.  Suspend conversations during hazardous driving conditions or situations. 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 and ice can 
be hazardous, but so is heavy traffic. As a driver, your first responsibility is to pay 
attention to the road.
5.  Do not take notes or look up phone numbers while driving. If you are reading an 
address book or business card, or writing a “to-do” list while driving a car, you 
are not watching where you are going. It is common sense. Don’t get caught in a 
dangerous situation because you are reading or writing and not paying attention to 
the road or nearby vehicles.
6.  Dial sensibly and assess the traffic; if possible, place calls when you are not moving 
or before pulling into traffic. Try to plan your calls before you begin your trip or 
attempt to coincide your calls with times you may be stopped at a stop sign, red light 
or otherwise stationary. But if you need to dial while driving, follow this simple tip — 
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. 
Stressful or emotional conversations and driving do not mix; they are distracting 
and even dangerous when you are behind the wheel of a car. Make people you are 
talking with aware you are driving and if necessary, suspend conversations which 
have the potential to divert your attention from the road.
8.  Use your wireless phone to call for help. Your wireless phone is one of the greatest 
tools you can own to protect yourself and your family in dangerous situations — 
with your phone at your side, help is only three numbers away. Dial 911 or other 
local emergency number in the case of fire, traffic accident, road hazard or medical 
emergency. Remember, it is a free call on your wireless phone! 
						

							28
9.  Use your wireless phone to help others in emergencies. Your wireless phone provides 
you a perfect opportunity to be a “Good Samaritan” in your community. If you see 
an auto accident, crime in progress or other serious emergency where lives are in 
danger, call 911 or other local emergency number, as you would want others to do 
for you.
10.  Call roadside assistance or a special wireless nonemergency assistance number 
when necessary. Certain situations you encounter while driving may require 
attention, but are not urgent enough to merit a call for emergency services. But you 
can still use your wireless phone to lend a hand. 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 wireless number.

Consumer Information on SAR 
(Specific Absorption Rate)
This Model Phone Meets the Government’s Requirements  for Exposure to Radio 
Waves.
Your wireless phone is a radio transmitter and receiver. It is designed and manufactured 
not to exceed the emission limits for exposure to radiofrequency (RF) energy set by 
the Federal Communications Commission (FCC) of the U.S. Government. These limits 
are part of comprehensive guidelines and establish permitted levels of RF energy for 
the general population. The guidelines are based on standards that were developed 
by independent scientific organizations through periodic and thorough evaluation of 
scientific studies. The standards include a substantial safety margin designed to assure 
the safety of all persons, regardless of age and health.
Safety Guidelines 
						

							29
The exposure standard for wireless mobile phones employs a unit of measurement 
known as the Specific Absorption Rate, or SAR. The SAR limit set by the FCC is 1.6 
W/kg. * Tests for SAR are conducted using standard operating positions specified by 
the FCC with the phone transmitting at its highest certified power level in all tested 
frequency bands.
Although SAR is determined at the highest certified power level, the actual SAR level of 
the phone while operating can be well below the maximum value. Because the phone 
is designed to operate at multiple power levels to use only the power required to reach 
the network, in general, the closer you are to a wireless base station antenna, the lower 
the power output.
Before a phone model is available for sale to the public, it must be tested and certified 
to the FCC that it does not exceed the limit established by the government adopted 
requirement for safe exposure. The tests are performed in positions and locations (e.g., 
at the ear and worn on the body) as required by the FCC for each model.
The highest SAR value for this model phone when tested for use at the ear is 1.09 
W/kg and when worn on the body, as described in this user’s manual, is 1.21 W/kg. 
(Body-worn measurements differ among phones models, depending upon available 
accessories and FCC/IC requirements.) While there may be differences between 
SAR levels of various phones and at various positions, they all meet the government 
requirement for safe exposure.
The FCC has granted an Equipment Authorization for this model phone with all reported 
SAR levels evaluated as in compliance with the FCC RF emission guidelines. SAR 
information on this model phone is on file with the FCC and can be found under the 
Display Grant section of http://www.fcc.gov/oet/ea/fccid after searching on FCC ID: 
ZNFE450G.
Additional information on Specific Absorption Rates (SAR) can be found on the Cellular 
Telecommunications Industry Association (CTIA) website at http://www.ctia.org/ 
						

							30
*  In the United States and Canada, the SAR limit for mobile phones used by the public 
is 1.6 watts/kg (W/kg) averaged over one gram of tissue. The standard incorporates a 
substantial margin of safety to give additional protection for the public and to account 
for any variations in measurements.
*  Product meets current FCC & IC Radio Frequency Exposure Guidelines.
