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.

Sur veillance, 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. Additional information about SEER can be found at

Cell Phone Industr y Actions
Although the existing scientific 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;
Use speaker mode or a headset to place more distance between your 
head and the cell phone. 
						

							167
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 users 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 phone. The phone may 
be forced to boost its power to compensate, leading to an 
increase in RF absorption.
Children and Cell Phones
The scientific 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 scientific evidence that any 
health hazard exists.
Additional information on the safety of RF exposures from various 
sources can be obtained from the following organizations

Specific Absorption Rate (SAR) Certification 
Infor mation
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 
Council 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. 
						

							169
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 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 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.
For body-worn operation, this phone 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 1.0 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 
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 in the FCC equipment 
authorization grant are:
WCDMA/GSM/EDGE
The highest reported SAR values are:
Head: 0.36 W/kg
Body-worn accessory: 0.78 W/kg
Product Specific Use: 0.90 W/kg
WLAN
The highest reported SAR values are:
Head: 0.19 W/kg
Body-worn accessory: 0.12 W/kg
Product Specific Use: 0.11 W/kg
SAR information on this and other model phones can be viewed 
online at http://www.fcc.gov/oet/ea. To find information that 
pertains to a particular model phone, this site uses the phone 
FCC ID number which is usually printed somewhere on the case 
of the phone.
Sometimes it may be necessary to remove the battery pack to 
find the number. Once you have the FCC ID number for a 
particular phone, follow the instructions on the website and it 
should provide values for typical or maximum SAR for a particular 
phone. Additional product specific 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, talking to 
passengers, or talking on a mobile phone - unless the driver has 
assessed the driving conditions and is confident 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  
						

							171
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 first, 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

Batter y 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  
						

							Health and Safety Information       172
pressure on the battery. This can cause leakage or an internal short-
circuit, resulting in overheating.
Do not let the phone or battery come in contact with liquids. Liquids can get into the phones circuits, leading to corrosion. Even 
when the phone appears to be dry and appears to operate normally, 
the circuitry could slowly corrode and pose a safety hazard. If the 
phone and/or battery get wet, have them checked by your service 
provider or contact Samsung, even if they appear to be working 
properly.
Do not place your battery in or near a heat source. Excessive 
heating can damage the phone or the battery and could cause the 
phone or the battery to explode. Do not dry a wet or damp battery with 
an appliance or heat source such as a microwave oven, hair dryer, 
iron, or radiator. Avoid leaving your phone in your car in high 
temperatures.
Do not dispose of the phone or the battery in a fire. The phone or 
the battery may explode when overheated.
Do not handle a damaged or leaking battery. Do not let leaking 
battery fluid come in contact with your eyes, skin or clothing. For safe 
disposal options, contact your nearest Samsung-authorized service 
center.
Avoid dropping the cell phone. Dropping the phone or the battery, 
especially on a hard surface, can potentially cause damage to the 
phone and battery. If you suspect damage to the phone or battery, take 
it to a service center for inspection.
Never use any charger or battery that is damaged in any way.
Do not allow the battery to touch metal objects. Accidental 
short-circuiting can occur when a metallic object (coin, key, jewelry, 
clip, or pen) causes a direct connection between the + and - terminals 
of the battery (metal strips on the battery), for example when you carry 
a spare battery in a pocket or bag. Short-circuiting the terminals may 
damage the battery or the object causing the short-circuiting.
Important!: Use only Samsung-approved batteries, and recharge your battery 
only with Samsung-approved chargers which are specifically 
designed for your phone.
Warning!: Use of a non-Samsung-approved battery or charger may present a 
risk of fire, explosion, leakage, or other hazard. Samsungs 
warranty does not cover damage to the phone caused by non-
Samsung-approved batteries and/or chargers.
Do not use incompatible cell phone batteries and chargers. Some 
websites and second-hand dealers not associated with reputable 
manufacturers and carriers, might be selling incompatible or even 
counterfeit batteries and chargers. Consumers should purchase 
manufacturer or carrier-recommended products and accessories. If 
unsure about whether a replacement battery or charger is compatible, 
contact the manufacturer of the battery or charger.
Misuse or use of incompatible phones, batteries, and charging 
devices could result in damage to the equipment and a possible  
						

							173
risk of fire, explosion, or leakage, leading to serious injuries, 
damages to your phone, or other serious hazard.

GPS & AGPS
Certain Samsung mobile devices can use a Global Positioning 
System (GPS) signal for location-based applications. A GPS uses 
satellites controlled by the U.S. Government that are subject to 
changes implemented in accordance with the Department of 
Defense policy and the 2008 Federal Radio navigation Plan (FRP). 
Changes may affect the performance of location-based 
technology on your mobile device.
Certain Samsung mobile devices can also use an Assisted Global 
Positioning System (AGPS), which obtains information from the 
cellular network to improve GPS performance. AGPS uses your 
wireless service providers network and therefore airtime, data 
charges, and/or additional charges may apply in accordance with 
your service plan. Contact your wireless service provider for 
details.
Your Location
Location-based information includes information that can be 
used to determine the approximate location of a mobile device. 
Mobile devices which are connected to a wireless network 
transmit location-based information. Additionally, if you use 
applications that require location-based information (e.g. driving 
directions), such applications transmit location-based 
information. The location-based information may be shared with 
third-parties, including your wireless service provider, applications providers, Samsung, and other third-parties 
providing services.
Use of AGPS in Emergency Calls
When you make an emergency call, the cellular network may 
activate AGPS technology in your mobile device to tell the 
emergency responders your approximate location.
AGPS has limitations and 
might not work in your area. Therefore:
Always tell the emergency responder your location to the best of your 
ability; and
Remain on the mobile device for as long as the emergency responder 
instructs you.
Navigation
Maps, directions, and other navigation data may contain 
inaccurate or incomplete data, and circumstances can and do 
change over time. In some areas, complete information may not 
be available. Therefore, 
you should always visually confirm that 
the navigational instructions are consistent with what you see 
before following them. All users should pay attention to road 
conditions, closures, traffic, and all other factors that may impact 
safe driving or walking. Always obey posted road signs
