Exposure to Radio Frequency
(RF) Signals
The U.S. Food and Drug Administration
(FDA) has published information for
consumers relating to Radio Frequency (RF)
exposure from wireless phones.
The FDA publication includes the
following information:
Do cell phones pose a health hazard?
Many people are concerned that cell phone
radiation will cause cancer or other serious
health hazards. The weight of scientiic
evidence has not linked cell phones with
any health problems.
Cell phones emit low levels of Radio
Frequency (RF) energy. Over the past 15
years, scientists have conducted hundreds
of studies looking at the biological effects
of the radio frequency energy emitted by
cell phones. While some researchers have
reported biological changes associated
with RF energy, these studies have
failed to be replicated. The majority of
studies published have failed to show an
association between exposure to radio
frequency from a cell phone and
health problems.
The low levels of RF cell phones emit while
in use are in the microwave frequency
range. They also emit RF at substantially
reduced time intervals 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

8 Important Health and Safety Information Important Health and Safety Information 9
produce heating effects causes no known
adverse health effects.
The biological effects of radio frequency
energy should not be confused
with the effects from other types of
electromagnetic energy.
Very high levels of electromagnetic energy,
such as is found in X-rays and gamma rays,
can ionize biological tissues. Ionization is a
process where electrons are stripped away
from their normal locations in atoms and
molecules. It can permanently damage
biological tissues including DNA, the
genetic material.
The energy levels associated with radio
frequency energy, including both radio
waves and microwaves, are not great
enough to cause ionization of atoms and
molecules. Therefore, RF energy is a type
of non-ionizing radiation. Other types of
non-ionizing radiation include visible light,
infrared radiation (heat), and other forms
of electromagnetic radiation with relatively
low frequencies.
While RF energy does not ionize particles,
large amounts can increase body
temperatures and cause tissue damage.
Two areas of the body, the eyes and the
testes, are particularly vulnerable to RF
heating because there is relatively little
blood low in them to carry away
excess heat.
Research Results to Date: Is there a
connection between RF and certain
health problems?
The results of most studies conducted
to date say no. In addition, attempts to
replicate and conirm the few studies that
have shown a connection have failed.
The scientiic community at large therefore
believes that the weight of scientiic

8 Important Health and Safety Information Important Health and Safety Information 9
evidence does not show an association
between exposure to Radio Frequency
(RF) from cell phones and adverse health
outcomes. Still the scientiic community
has supported additional research to
address gaps in knowledge. Some of these
studies are described below.
Interphone Study
Interphone is a large international study
designed to determine whether cell
phones increase the risk of head and
neck cancer. A report published in the
International Journal of Epidemiology
(June, 2010) compared cell phone usage for
more than 5,000 people with brain tumors
(glioma and meningioma) and a similar
number of healthy controls.
Results of this study did NOT show that cell
phones caused brain cancer. In this study,
most people had no increased risk of brain
cancer from using cell phones. For people
with the heaviest use of cell phones (an
average of more than ½ hour per day, every
day, for over 10 years) the study suggested
a slight increase in brain cancer. However,
the authors determined that biases
and errors prevented any conclusions
being drawn from this data. Additional
information about Interphone can be found
at www.iarc.fr/en/media-centre/pr/2010/
pdfs/pr200_E.pdf.
Interphone is the largest cell phone study
to date, but it did not answer all questions
about cell phone safety. Additional
research is being conducted around the
world, and the FDA continues to monitor
developments in this ield.

International Cohort Study on Mobile
Phone Users (COSMOS)
The COSMOS study aims to conduct
long-term health monitoring of a large
group of people to determine if there
are any health issues linked to long-term
exposure to radio frequency energy from
cell phone use. The COSMOS study will
follow approximately 300,000 adult cell
phone users in Europe for 20 to 30 years.
Additional information about the COSMOS
study can be found at www.ukcosmos.org/
index.html.
Risk of Brain Cancer from Exposure to
Radio Frequency Fields in Childhood
and Adolescence (MOBI-KIDS)
MOBI-KIDS is an international study
investigating the relationship between
exposure to radio frequency energy
from communication technologies
including cell phones and brain cancer
in young people. This is an international
multi-center study involving 14 European
and non-European countries. Additional
information about MOBI-KIDS can be found
at www.creal.cat/programes-recerca/
en_projectes-creal/view.php?ID=39.
Surveillance, Epidemiology, and End
Results (SEER) Program of the National
Cancer Institute
The National Cancer Institute (NCI) actively
follows cancer statistics in the United
States to detect any change in rates of new
cases for brain cancer. If cell phones play
a role in risk for brain cancer, rates should
go up, because heavy cell phone use has
been common for quite some time in the
U.S. Between 1987 and 2005, the overall
age-adjusted incidence of brain cancer did
not increase.

Cell Phone Industry Actions
Although the existing scientiic data do
not justify FDA regulatory actions, the FDA
has urged the cell phone industry to take a
number of steps, including the following:
• Support-needed research on possible
biological effects of RF for the type of
signal emitted by cell phones;
• Design cell phones in a way that
minimizes any RF exposure to the
user; and
• Cooperate in providing users of cell
phones with the current information
on cell phone use and human
health concerns.
The FDA also is working with voluntary
standard-setting bodies such as the
Institute of Electrical and Electronics
Engineers (IEEE), the International
Commission on Non-Ionizing Radiation
Protection (ICNIRP), and others to
assure that safety standards continue to
adequately protect the public.
Reducing Exposure: Hands-Free Kits
and Other Accessories
Steps to Reduce Exposure to Radio
Frequency Energy
If there is a risk from being exposed to radio
frequency energy (RF) from cell phones -
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 RF exposure.
• Reduce the amount of time spent using
your cell phone;

12 Important Health and Safety Information Important Health and Safety Information 13
• Use speaker mode or a headset to place
more distance between your head and
the cell phone.
Hands-Free Kits
Hands-free kits may include audio or
Bluetooth® headsets and various types of
body-worn accessories such as belt-clips
and holsters. Combinations of these can be
used to reduce RF energy absorption from
cell phones.
Headsets can substantially reduce
exposure because the phone is held
away from the head in the user's hand
or in approved body-worn accessories.
Cell phones marketed in the U.S. are
required to meet RF exposure compliance
requirements when used against the head
and against the body.
Because there are no known risks from
exposure to RF emissions from cell phones,
there is no reason to believe that hands-free
kits reduce risks. Hands-free kits can be
used for convenience and comfort. They
are also required by law in many states if
you want to use your phone while driving.
Cell Phone Accessories that Claim to
Shield the Head from RF Radiation
Because there are no known risks from
exposure to RF emissions from cell
phones, there is no reason to believe that
accessories which 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
“hands-free” kits, these so-called “shields”
may interfere with proper operation of the

12 Important Health and Safety Information Important Health and Safety Information 13
phone. The phone may be forced to boost
its power to compensate, leading to an
increase in RF absorption.
Children and Cell Phones
The scientiic evidence does not show a
danger to any users of cell phones from
RF exposure, including children and
teenagers. The steps adults can take to
reduce RF exposure apply to children and
teenagers as well.
• Reduce the amount of time spent on the
cell phone;
• Use speaker mode or a headset to place
more distance between the head and the
cell phone.
Some groups sponsored by other national
governments have advised that children
be discouraged from using cell phones
at all. For example, The Stewart Report
from the United Kingdom made such a
recommendation in December 2000. In
this report, a group of independent experts
noted that no evidence exists that using
a cell phone causes brain tumors or other
ill effects. Their recommendation to limit
cell phone use by children was strictly
precautionary; it was not based
on scientiic evidence that any health
hazard exists.

exposures from various sources can be
obtained from the following organizations

Speciic Absorption Rate (SAR)
Certiication Information
Your wireless device 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 RF exposure limits are derived
from the recommendations of two expert
organizations: the National Council on
Radiation Protection and Measurement
(NCRP) and the Institute of Electrical and

14 Important Health and Safety Information Important Health and Safety Information 15
Electronics Engineers (IEEE). In both cases,
the recommendations were developed by
scientiic and engineering experts drawn
from industry, government, and academia
after extensive reviews of the scientiic
literature related to the biological effects of
RF energy.
The RF exposure limit set by the FCC for
wireless mobile phones employs a unit
of measurement known as the Speciic
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 SAR 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
certiied power level in all tested frequency
bands. Although the SAR is determined at
the highest certiied power level, the actual
SAR level of the phone while operating can
be well below the maximum reported value.
This is because the phone is designed to
operate at multiple power levels so as 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 of the device.
Before a new model device is available for
sale to the public, it must be tested and
certiied to the FCC that it does not exceed
the SAR limit established by the FCC. Tests
for each model phone are performed in

16 Important Health and Safety Information Important Health and Safety Information 17
positions and locations (e.g. at the ear and
worn on the body) as required by the FCC.
For body-worn operation, this device has
been tested and meets FCC RF exposure
guidelines when used with an accessory
that contains no metal and that positions
the mobile device a minimum of 1.5 cm
from the body. Use of other accessories
may not ensure compliance with FCC RF
exposure guidelines. The FCC has granted
an Equipment Authorization for this
mobile device 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:
Simultaneous Transmission Head:
1.24 W/Kg
Simultaneous Transmission Body-worn:
1.52 W/Kg
The SAR information for this device can also
be found on Samsung’s website:
www.samsung.com/sar.
SAR information on this and other mobile
devices can be accessed online on the
FCC’s website through http://transition.
fcc.gov/oet/rfsafety/sar.html. To ind
information that pertains to a particular
model, this site uses the device FCC
ID number which is usually printed
somewhere on the case of the device.
Sometimes it may be necessary to remove
the battery pack to ind the number. Once
you have the FCC ID number for a particular
device, follow the instructions on the
website and it should provide values for
typical or maximum SAR for a particular
phone. Additional SAR information can also
be obtained at

Smart Practices While Driving
On the Road - Off the Phone
The primary responsibility of every driver is
the safe operation of his or her vehicle.
Responsible drivers understand that no
secondary task should be performed while
driving whether it be eating, drinking,

18 Important Health and Safety Information Important Health and Safety Information 19
talking to passengers, or talking on a
mobile phone - unless the driver has
assessed the driving conditions and is
conident that the secondary task will not
interfere with their primary responsibility.
Do not engage in any activity while driving
a moving vehicle which may cause you to
take your eyes off the road or become so
absorbed in the activity that your ability to
concentrate on the act of driving becomes
impaired. Samsung is committed to
promoting responsible driving and giving
drivers the tools they need to understand
and address distractions.
Check the laws and regulations on the use
of mobile devices and their accessories
in the areas where you drive. Always obey
them. The use of these devices may be
prohibited or restricted in certain areas.
For example, only hands-free use may be
permitted in certain areas.
Before answering calls, consider your
circumstances. Let the call go to voicemail
when driving conditions require.
Remember, driving comes irst, not the call!
If you consider a call necessary and
appropriate, follow these tips:
• Use a hands-free device;
• Secure your phone within easy reach;
• Place calls when you are not moving;
• Plan calls when your car will be stationary;
• Do not engage in stressful or emotional
conversations;
• Let the person with whom you are
speaking know that you are driving and
will suspend the call if necessary;
• Do not take notes or look up phone
numbers while driving;

Battery Use and Safety
Important: Handle and store batteries
properly to avoid injury
or damage. Most battery
issues arise from improper
handling of batteries and,
particularly, from the
continued use of
damaged batteries.
• Do not disassemble, crush, puncture,
shred, or otherwise attempt to change
the form of your battery. Do not put a
high degree of pressure on the battery.
This can cause leakage or an internal
short-circuit, resulting in overheating.
