Safety warnings

Keep your phone away from small children and pets

Keep your phone and all accessories out of the reach of small children or animals.
Small parts may cause choking or serious injury if swallowed.

Protect your hearing

Excessive exposure to sound at high volumes can cause hearing damage.

Always turn the volume down before plugging the earphones into an audio source and
use only the minimum volume setting necessary to hear your conversation or music.

Install mobile phones and equipment with caution

Ensure that any mobile phones or related equipment installed in your vehicle are
securely mounted. Avoid placing your phone and accessories near or in an air bag
deployment area. Improperly installed wireless equipment can cause serious injury
when air bags inflate rapidly.

Handle and dispose of batteries and chargers with care

 Use only Samsung-approved batteries and chargers specifically designed for

your phone. Incompatible batteries and chargers can cause serious injuries
or damage to your phone.

 Never dispose of batteries or phones in a fire. Follow all local regulations

when disposing used batteries or phones.

 Never place batteries or phones on or in heating devices, such as microwave

ovens, stoves, or radiators. Batteries may explode when overheated.

 Never crush or puncture the battery. Avoid exposing the battery to high

external pressure, which can lead to an internal short circuit and overheating.

Avoid interference with pacemakers

Maintain a minimum of 15 cm (6 inches) between mobile phones and pacemakers to
avoid potential interference, as recommended by manufacturers and the
independent research group, Wireless Technology Research. If you have any reason
to suspect that your phone is interfering with a pacemaker or other medical device,
turn off the phone immediately and contact the manufacturer of the pacemaker or
medical device for guidance.

Turn off the phone in potentially explosive environments

Do not use your phone at refuelling points (service stations) or near fuels or
chemicals. Turn off your phone whenever directed by warning signs or instructions.
Your phone could cause explosions or fire in and around fuel or chemical storage
and transfer areas or blasting areas. Do not store or carry flammable liquids, gases,
or explosive materials in the same compartment as the phone, its parts, or
accessories.

Reduce the risk of repetitive motion injuries

When sending text messages or playing games on your phone, hold the phone with
a relaxed grip, press the keys lightly, use special features that reduce the number of
keys you have to press (such as templates and predictive text), and take frequent
breaks.

Safety precautions

Drive safely at all times

Avoid using your phone while driving and obey all regulations that restrict the use of
mobile phones while driving. Use hands-free accessories to increase your safety
when possible.

Using incompatible accessories may damage your phone or cause injury.

Turn off the phone near medical equipment

Your phone can interfere with medical equipment in hospitals or health care facilities.
Follow all regulations, posted warnings, and directions from medical personnel.

Turn off the phone or disable the wireless functions when in an aircraft

Your phone can cause interference with aircraft equipment. Follow all airline
regulations and turn off your phone or switch to a mode that disables the wireless
functions when directed by airline personnel.

Protect batteries and chargers from damage

Avoid exposing batteries to very cold or very hot temperatures (below 0° C/32° F or

above 45° C/ 113° F). Extreme temperatures can reduce the charging capacity and
life of your batteries.

Prevent batteries from contacting metal objects, as this can create a connection

between the + and - terminals of your batteries and lead to temporary or permanent
battery damage.

Never use a damaged charger or battery.

Handle your phone carefully and sensibly

Do not allow your phone to get wet—liquids can cause serious damage. Do not

handle your phone with wet hands. Water damage to your phone can void your
manufacturer’s warranty.

 Avoid using or storing your phone in dusty, dirty areas to prevent damage to

operation.

 Avoid using the phone’s camera flash or light close to the eyes of children or

animals.

 Your phone and memory cards may be damaged by exposure to magnetic

fields. Do not use carrying cases or accessories with magnetic closures or
allow your phone to come in contact with magnetic fields for extended

periods of time.

Avoid interference with other electronic devices

Your phone emits radio frequency (RF) signals that may interfere with unshielded or
improperly shielded electronic equipment, such as pacemakers, hearing aids,
medical devices, and other electronic devices in homes or vehicles. Consult the
manufacturers of your electronic devices to solve any interference problems you
experience.

Important usage information

Use your phone in the normal position

Avoid contact with your phone’s internal antenna.

Allow only qualified personnel to service your phone

Allowing unqualified personnel to service your phone may result in damage to your
phone and will void your warranty.

Ensure maximum battery and charger life

 Avoid charging batteries for more than a week, as overcharging may shorten

battery life.

 Over time, unused batteries will discharge and must be recharged before use.
 Disconnect chargers from power sources when not in use.
 Use batteries only for their intended purpose.

Handle SIM cards and memory cards with care

 Do not remove a card while the phone is transferring or accessing

information, as this could result in loss of data and/or damage to the card or
phone.

 Protect cards from strong shocks, static electricity, and electrical noise from

other devices.

 Frequent writing and erasing will shorten the life span of memory cards.
 Do not touch gold-coloured contacts or terminals with your fingers or metal

objects. If dirty, wipe the card with a soft cloth.

Ensure access to emergency services

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.

Health and safety information

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 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 model phone has been tested and meets
the FCC RF exposure guidelines when used with a Samsung accessory
designated for this product or when used with an accessory that contains
no metal and that positions the handset a minimum of 1.5 cm from the
body.

Non-compliance with the above restrictions may result in violation of FCC
RF exposure guidelines.

SAR information on this and other model phones can be viewed on-line at

http://www.fcc.gov/oet/ea/fccid/. This site uses the phone FCC ID number,

A3LGTS7230B. 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 www.fcc.gov/cgb/sar.

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 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 well within the FCC's compliance limits.
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

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 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.
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 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.

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.
