Handle and dispose of batteries and chargers
with care
Turn off the phone in potentially explosive
environments
• 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.

Comply with the following precautions to avoid dangerous or illegal situations and ensure peak performance of your mobile phone.
Reduce the risk of repetitive motion injuries
While using 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.
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.
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.
Do not use the phone if the screen is cracked or
broken
Handle your phone carefully and sensibly
Avoid interference with other electronic devices
• Do not allow your phone to get wet—liquids can cause
serious damage and will change the colour of the label
that indicates water damage inside the phone. 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 moving parts.
• Your phone is a complex electronic device—protect
it from impacts and rough handling to avoid serious
damage.
• Do not paint your phone, as paint can clog moving
parts and prevent proper operation.
• If your phone has a camera flash or light, avoid using it
close to the eyes of children or animals.
• Your phone 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.
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.
Allow only qualified personnel to service your
phone
Broken glass or acrylic could cause injury to your hand
and face. Bring the phone to a Samsung service centre
to replace the screen. Damage caused by careless
handling will void your manufacturer’s warranty.
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.
Follow all safety warnings and regulations
Comply with any regulations that restrict the use of a
mobile phone in a certain area.
Use only Samsung-approved accessories
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.
In normal use, the actual SAR is likely to be much
lower, as the phone has been designed to emit only
the RF energy necessary to transmit a signal to the
nearest base station. By automatically emitting lower
levels when possible, your phone reduces your overall
exposure to RF energy.
The FCC has granted an Equipment Authorization
for this model phone based on the compliance of
all reported SAR levels with the FCC RF exposure
guidelines. The authorization can be found on the FCC
Office of Engineering and Technology website at
http://www.fcc.gov/oet/ea (search for grantee code A3L
and product code GTM2520).
Important usage information
Use your phone in the normal position
Avoid contact with your phone's internal antenna.
Allowing unqualified personnel to service your phone
may result in damage to your phone and will void your
warranty.
Emergency calls from your phone may not be possible
in some areas or circumstances. Before traveling in
remote or undeveloped areas, plan an alternate method
of contacting emergency services personnel.
Ensure maximum battery and charger life
SAR information
• 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-colored contacts or terminals with
your fingers or metal objects. If dirty, wipe the card with
a soft cloth.

Health and safety information
Exposure to Radio Frequency (RF) Signals
Your wireless phone is a radio transmitter and receiver.
It is designed and manufactured not to exceed the
emission limits for exposure to radio frequency (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 the safety
standards that were developed by independent
scientific organizations through periodic and through
evaluation of scientific studies.
The standards include a substantial safety margin
designed to assure the safety of all persons,
regardless of age and health.
The exposure standard for wireless phones employs a
unit of measurement known as Specific Absorption
Rate (SAR). The SAR limit recommended by the FCC is
1.6W/kg.*
R400.book Page 17 Friday, January 11, 2008 9:45 AM
SAR tests 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.
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 limit established by the
government adopted 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 exposure
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/fccid after
searching on FCC ID printed in the label on the phone.
Health and safety information
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 of the phone.
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. While there may be
differences between the SAR levels of various phones
and at various positions, they all meet the government
requirement.
* In the U.S. 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.

when used with a Samsung-supplied or approved
accessory designated for this product or when used
with and accessory that contains no metal and that
positions the handset a minimum from the body.

Never use any charger or battery that is damaged
in any way.
Use the battery only for its intended purpose.
If you use the phone near the network’s base
station, it uses less power; talk and standby time
are greatly affected by the signal strength on the
cellular network and the parameters set by the
network operator.
Battery charging time depends on the remaining
battery charge, the type of battery and the charger
used. The battery can be charged and discharged
hundreds of times, but it will gradually wear out.
When the operation time (talk time and standby
time) is noticeably shorter than normal, it is time
to buy a new battery.
If left unused, a fully charged battery will
discharge itself over time.

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:
• 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.
• When available, use a hands-free device. If
possible, add an extra layer of convenience and
Health and safety information
•
Use only Samsung-approved batteries and
recharge your battery only with Samsungapproved chargers. When a charger is not in use,
disconnect it from the power source. Do not leave
the battery connected to a charger for more than a
week, since overcharging may shorten its life.
Extreme temperatures will affect the charging
capacity of your battery: it may require cooling or
warming first.
Do not leave the battery in hot or cold places, such
as in a car in summer or winter conditions, as you
will reduce the capacity and lifetime of the battery.
Always try to keep the battery at room
temperature. A phone with a hot or cold battery
may temporarily not work, even when the battery
is fully charged. Li-ion batteries are particularly
affected by temperatures below 0 °C (32 °F).
Do not short-circuit the battery. Accidental shortcircuiting can occur when a metallic object (coin,
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

safety to your wireless phone with one of the many
hands-free accessories available today.
Position your wireless phone within easy reach. Be
able to access your wireless phone without
removing your eyes from the road. If you get an
incoming call at an inconvenient time, let your
voice mail answer it for you.
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.
Do not take notes or look up phone numbers while
driving. Jotting down a To Do list or flipping
through your Address Book takes your attention
away from your primary responsibility, driving
safely.
•
•
•
•
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.
Do not engage in stressful or emotional
conversations that may be distracting. Make the
people with whom you are talking aware that you
are driving and suspend conversations that have
the potential to divert your attention from the
road.
Use your wireless phone to call for help. Dial the
emergency number in the case of fire, traffic
accident or medical emergencies. Remember, it is
a free call on your wireless phone!
Use your wireless phone to help others in
emergencies. If you see a car accident, crime in
progress or other serious emergency where lives
are in danger, call the emergency number, as you
would want others to do for you.

Operating environment
Remember to follow any special regulations in force in
any area and always switch off your phone 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 used
in the normal operating position (held to your ear with
the antenna pointing over your shoulder).
Electronic devices
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.
Health and safety information
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 any other special non-emergency
wireless number.
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.

Health and safety information
If you have any reason to suspect that interference is
taking place, switch off your phone immediately.
Hearing aids
Some digital wireless phones may interfere with some
hearing aids. In the event of such interference, you
may wish to consult your hearing aid manufacturer to
discuss alternatives.
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 off your phone in health care
facilities when any regulations posted in these areas
instruct you to do so. Hospitals or health care facilities
may be using equipment that could be sensitive to
external RF energy.
Vehicles
RF signals may affect improperly installed or
inadequately shielded electronic systems in motor
vehicles. Check with the manufacturer or its
representative regarding your vehicle. You should also
consult the manufacturer of any equipment that has
been added to your vehicle. You should also consult
the manufacturer of any equipment that has been

Emergency calls
Switch off your phone when in any area with a
potentially explosive atmosphere and obey all signs
and instructions. Sparks in such areas could cause an
explosion or fire resulting in bodily injury or even
death.
This phone, like any wireless phone, operates using
radio signals, wireless and landline networks as well as
user-programmed functions, which cannot guarantee
connection in all conditions. Therefore, you should
never rely solely on any wireless phone for essential
communications (medical emergencies, for example).
Users are advised to switch off the phone while at a
refueling point (service station). Users are reminded of
the need to observe restrictions on the use of radio
equipment in fuel depots (fuel storage and distribution
areas), chemical plants or where blasting operations
are in progress.
Areas with a potentially explosive atmosphere are
often but not always clearly marked. They include the
areas below deck on boats, chemical transfer or
storage facilities, vehicles using liquefied petroleum
gas (such as propane or butane), areas where the air
contains chemicals or particles, such as grain, dust or
metal powders, and any other area where you would
normally be advised to turn off your vehicle engine.
Remember, to make or receive any calls the phone
must be switched on and in a service area with
adequate signal strength. Emergency calls may not be
possible on all wireless phone networks or when
certain network services and/or phone features are in
use. Check with local service providers.
To make an emergency call:

Cautions
Changes or modifications made in the radio phone, not
expressly approved by Samsung, will void the user’s
authority to operate the equipment.
Although your phone is quite sturdy, it is a complex
piece of equipment and can be broken. Avoid
dropping, hitting, bending or sitting on it.
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 radio frequency (RF)
energy set by the Federal Communications
Commission 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 safety
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.
Health and safety information
Only use approved batteries, antennas and chargers.
The use of any unauthorized accessories may be
dangerous and void the phone warranty if said
accessories cause damage or a defect to the phone.
Appendix A: CERTIFICATION
INFORMATION (SAR)
The exposure standard for wireless mobile phones
employs a unit of measurement known as the Specific
Absorption Rate (SAR). The SAR limit set by the FCC is
1.6 W/kg. SAR Tests are conducted using standard
27
R400.book Page 28 Friday, January 11, 2008 9:45 AM
Health and safety information
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.
Body-worn operations are restricted to Samsungsupplied, approved or none Samsung designated
accessories that have no metal and must provide at
least 1.5cm separation between the device, including
its antenna whether extended or retracted, and the
user’s body. None compliance to the above restrictions
may violate FCC RF exposure guidelines.
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 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 FCC has granted an Equipment Authorization for
this model phone with all reported SAR levels
evaluated as in compliance with the FCC RF exposure
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/fccid after
searching on FCC ID A3LGTM2520.*
*In the United States and Canada, the SAR limit for mobile
phones used by the public is 1.6 watts/kilogram (W/kg) averaged over one gram of tissue. The standard incorporates a substantial ma gin of safety togive additional protection for the
public and to account for any variations in measurements.

Wireless Phone “Safety Tips”
Below are safety tips to follow while driving and using
a wireless phone which should be easy to remember:
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 hands free device. A number
of hands free 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 grab it without
removing your eyes from the road. If you get an
incoming call at an inconvenient time, if possible,
let your voice mail answer it for you.
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’s 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.
R400.book Page 31 Friday, January 11, 2008 9:45 AM
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!
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 9-1-1 or other local
emergency number, as you would want others to
do for you.
10. Call roadside assistance or a special wireless non
emergency 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 still
can 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
Health and safety information
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 mixthey 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 9-1-1 or

you know to be stolen, call roadside assistance or
other special non-emergency wireless number.
Careless, distracted individuals and people driving
irresponsibly represent a hazard to everyone on the
road. Since 1984, the Cellular Telecommunications
Industry Association and the wireless industry have
conducted educational outreach to inform wireless
phone users of their responsibilities as safe drivers
and good citizens. As we approach a new century,
more and more of us will take advantage of the
benefits of wireless telephones.
And, as we take to the roads, we all have a
responsibility to drive safely.

Appendix C: Consumer Update on
Wireless Phones
U.S. Food and Drug Administration
1. 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
R400.book Page 33 Friday, January 11, 2008 9:45 AM
thus produce RF exposures well within the FCC’s
compliance limits.
2. Do wireless phones pose a health hazard?
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;
Health and safety information
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.
3. What is FDA’s role concerning the safety of wireless
phones?
33
R400.book Page 34 Friday, January 11, 2008 9:45 AM
Health and safety information
•
•
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.
4. 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).
R400.book Page 35 Friday, January 11, 2008 9:45 AM
FDA and the 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.
5. 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
Health and safety information
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.
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
35
R400.book Page 36 Friday, January 11, 2008 9:45 AM
Health and safety information
use measures like those described above to reduce
your RF exposure from wireless phone use.
6. 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 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.
7. 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. Hands-free
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.
R400.book Page 37 Friday, January 11, 2008 9:45 AM
8. Do wireless phone accessories that claim to shield
the head from RF radiation work?
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
Health and safety information
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.
9. 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 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.

R400.book Page 38 Friday, January 11, 2008 9:45 AM
Health and safety information
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.
10.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 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, gioma,
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.
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.
11. 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 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.
