Emergency calls from your phone may not be possible
in some areas or circumstances. Before travelling in
remote or undeveloped areas, plan an alternate
method of contacting emergency services personnel.
Exposure to Radio Frequency (RF)
Signals
Certification Information (SAR)
Your wireless phone is a radio transmitter and
receiver. It is designed and manufactured not to
exceed the exposure limits for radio frequency (RF)
energy set by the Federal Communications
Commission (FCC) of the U.S. government. These
FCC exposure limits are derived from the
recommendations of two expert organizations, the
National Counsel on Radiation Protection and
Measurement (NCRP) and the Institute of Electrical
and Electronics Engineers (IEEE). In both cases, the
recommendations were developed by scientific and
engineering experts drawn from industry,
government, and academia after extensive reviews
of the scientific literature related to the biological
effects of RF energy.
The exposure limit set by the FCC for wireless
mobile phones employs a unit of measurement
known as the Specific Absorption Rate (SAR). The
SAR is a measure of the rate of absorption of RF
energy by the human body expressed in units of
watts per kilogram (W/kg). The FCC requires
wireless phones to comply with a safety limit of 1.6
watts per kilogram (1.6 W/kg). The FCC exposure
limit incorporates a substantial margin of safety to
give additional protection to the public and to
account for any variations in measurements.
SAR tests are conducted using standard operating
positions accepted by the FCC with the phone
transmitting at its highest certified power level in all
tested frequency bands. Although the 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. This is because the
phone is designed to operate at multiple power
levels so as to use only the power required to reach
safety and usage information
9
the network. In general, the closer you are to a
wireless base station antenna, the lower the power
output.
Before a new model phone is available for sale to the
public, it must be tested and certified to the FCC that
safety and usage information
it does not exceed the exposure limit established by
the FCC. Tests for each model phone are performed
in positions and locations (e.g. at the ear and worn on
the body) as required by the FCC.
The FCC has granted an Equipment Authorization for
this mobile phone with all reported SAR levels
evaluated as in compliance with the FCC RF
exposure guidelines. The maximum SAR values for
this model phone as reported to the FCC are:
GSM1900
Head: 0.079 W/kg.
Body-worn: 0.211 W/kg.

Consumer Information on Wireless
Phones
The U.S. Food and Drug Administration (FDA) has
published a series of Questions and Answers for
consumers relating to radio frequency (RF) exposure
from wireless phones. The FDA publication includes
the following information:
What kinds of phones are the subject
of this update?
The term wireless phone refers here to hand-held
wireless phones with built-in antennas, often called
“cell,” “mobile,” or “PCS” phones. These types of
wireless phones can expose the user to measurable
radio frequency energy (RF) because of the short
distance between the phone and the user's head.
These RF exposures are limited by Federal
Communications Commission safety guidelines that
were developed with the advice of FDA and other
federal health and safety agencies. When the phone
11
safety and usage information
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
safety and usage information
connected to the telephone wiring in a house,
typically operate at far lower power levels, and thus
produce RF exposures well within the FCC's
compliance limits.
12
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 energy
(RF) in the microwave range while being used. They
also emit very low levels of RF when in the stand-by
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.
What is FDA's role concerning the
safety of wireless phones?
Under the law, 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 energy
(RF) at a level that is hazardous to the user. In such a
case, 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.
Although the existing scientific data do not justify
FDA regulatory actions, 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.
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
• “Federal Communications Commission
• “Occupational Safety and Health Administration
• “National Telecommunications and Information
Administration
safety and usage information
13
The National Institutes of Health participates in some
interagency working group activities, as well.
FDA shares regulatory responsibilities for wireless
phones with the Federal Communications
Commission (FCC). All phones that are sold in the
safety and usage information
United States must comply with FCC safety
guidelines that limit RF exposure. FCC relies on FDA
and other health agencies for safety questions about
wireless phones.
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
primary subject of the safety questions discussed in
this document.
14
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 cancercausing 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 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 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.
safety and usage information
15
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
safety and usage information
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
16
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.
safety and usage information
17
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
safety and usage information
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.
18
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. Handsfree 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. According to FTC, these defendants lacked
a reasonable basis to substantiate their claim.
safety and usage information
19
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
safety and usage information
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
20
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.

Road Safety
Your wireless phone gives you the powerful ability to
communicate by voice, almost anywhere, anytime.
But an 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
safety and usage information
21
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
safety and usage information
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
22
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. Remember, it is
a free call on your wireless phone!
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 nonemergency wireless assistance number
when necessary. If you see a brokendown 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 nonemergency number.

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
user's 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
safety and usage information
23
used in the normal operating position (held to your
ear with the antenna pointing over your shoulder).
Using Your Phone Near Other
Electronic Devices
safety and usage information
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.
Pacemakers
Pacemaker manufacturers recommend that a
minimum distance of 15 cm (6 inches) be
maintained between a wireless phone and a
pacemaker to avoid potential interference with the
pacemaker.
These recommendations are consistent with the
independent research and recommendations of
Wireless Technology Research.
24
Persons with pacemakers:
• should always keep the phone more than 15 cm
(6 inches) from their pacemaker when the phone
is switched on.
• should not carry the phone in a breast pocket.
• should use the ear opposite the pacemaker to
minimize potential interference.
If you have any reason to suspect that interference is
taking place, switch your phone off immediately.
Hearing Aid Compatibility with Mobile
Phones
When some mobile 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
ratings for some of their mobile phones, to assist
hearing device users in finding 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 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 be more usable with a
hearing device°Øs telecoil (°×T Switch°± or
°×Telephone Switch°±) than unrated phones. T4 is
the better/higher of the two ratings. (Note that not all
hearing devices have telecoils in them.)Hearing
devices may also be measured for immunity to this
type of interference. Your hearing device
manufacturer or hearing health professional may
help you find results for your hearing device. The
more immune your hearing aid is, the less likely you
are to experience interference noise from mobile
phones.
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
