Explosion, Shock, and Fire Hazards
O  Do not put your phone in a place subject to excessive dust and keep the 
minimum required distance between the power cord and heat sources.
O  Unplug the power cord prior to cleaning your phone, and clean the power 
plug pin when it’s dirty.
O  When using the power plug, ensure that it’s firmly connected. If not, it 
may cause excessive heat or fire.
O  If you put your phone in a pocket or bag without covering the receptacle 
of the phone (power plug pin), metallic articles (such as a coin, paperclip 
or pen) may short-circuit the phone. Always cover the receptacle when 
not in use.
O  Don’t short-circuit the battery. Metallic articles such as a coin, paperclip 
or pen in your pocket or bag may short-circuit the + and – terminals of 
the battery (metal strips on the battery) upon moving. Short-circuit of the 
terminal may damage the battery and cause an explosion.
General Notice
O  Using a damaged battery or placing a battery in your mouth may cause 
serious injury.
O  Do not place items containing magnetic components such as a credit 
card, phone card, bank book, or subway ticket near your phone. The 
magnetism of the phone may damage the data stored in the magnetic 
strip.
O  Talking on your phone for a long period of time may reduce call quality 
due to heat generated during use.
O  When the phone is not used for a long period time, store it in a safe 
place with the power cord unplugged.
O  Using the phone in proximity to receiving equipment (i.e., TV or radio) 
may cause interference to the phone.
O  Do not use the phone if the antenna is damaged. If a damaged 
antenna contacts skin, it may cause a slight burn. Please contact an LG 
Authorized Service Center to replace the damaged antenna. 
						

							190Safety
O  Do not immerse your phone in water. If this happens, turn it off 
immediately and remove the battery. If the phone does not work, take it 
to an LG Authorized Service Center.
O  Do not paint your phone.
O  The data saved in your phone might be deleted due to careless use, 
repair of the phone, or upgrade of the software. Please backup your 
important phone numbers. (Ringtones, text messages, voice messages, 
pictures, and videos could also be deleted.) The manufacturer is not 
liable for damage due to the loss of data.
O  When you use the phone in public places, set the ringtone to vibration so 
you don’t disturb others.
O  Do not turn your phone on or off when putting it to your ear.
O  Use accessories, such as earphones and headsets, with caution. 
Ensure that cables are tucked away safely and do not tap the antenna 
unnecessarily.
Caution: Avoid potential hearing loss.
Prolonged exposure to loud sounds (including music) is the most common 
cause of preventable hearing loss. Some scientific research suggests 
that using portable audio devices, such as portable music players and 
cellular telephones, at high volume settings for long durations may lead to 
permanent noise induced hearing loss. This includes the use of headphones 
(including headsets, earbuds and Bluetooth
® or other wireless devices). 
Exposure to very loud sound has also been associated in some studies 
with tinnitus (a ringing in the ear), hypersensitivity to sound and distorted 
hearing. Individual susceptibility to noise-induced hearing loss and other 
potential hearing problems varies.
The amount of sound produced by a portable audio device varies depending 
on the nature of the sound, the device, the device settings and the 
headphones. You should follow some commonsense recommendations 
when using any portable audio device: 
						

							191Safety
O  Set the volume in a quiet environment and select the lowest volume at 
which you can hear adequately.
O  When using headphones, turn the volume down if you cannot hear the 
people speaking near you or if the person sitting next to you can hear 
what you are listening to.
O  Do not turn the volume up to block out noisy surroundings. If you choose 
to listen to your portable device in a noisy environment, use noise-
cancelling headphones to block out background environmental noise.
O  Limit the amount of time you listen. As the volume increases, less time 
is required before your hearing could be affected.
O  Avoid using headphones after exposure to extremely loud noises, such 
as rock concerts, that might cause temporary hearing loss. Temporary 
hearing loss might cause unsafe volumes to sound normal.
O  Do not listen at any volume that causes you discomfort. If you 
experience ringing in your ears, hear muffled speech or experience any 
temporary hearing difficulty after listening to your portable audio device, 
discontinue use and consult your doctor.

FDA Consumer Update
 The U.S. Food and Drug Administration’s Center for Devices 
and Radiological Health Consumer Update on Mobile Phones:
1. 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 (RF) energy in the microwave range while being used. They also 
emit very low levels of RF when in standby 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.
2. What is the FDA’s role concerning the safety of wireless phones?
Under the law, the 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 (RF) energy at a level that is hazardous to the user. In such a 
case, the 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 does not justify FDA regulatory actions, 
the FDA has urged the wireless phone industry to take a number of steps, 
including the following:
O  Support needed research into possible biological effects of RF of the 
type emitted by wireless phones; 
						

							194Safety
O  Design wireless phones in a way that minimizes any RF exposure to the 
user that is not necessary for device function; and
O  Cooperate in providing users of wireless phones with the best possible 
information on possible effects of wireless phone use on human health.
The 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:
O  National Institute for Occupational Safety and Health
O Environmental Protection Agency
O  Occupational Safety and Health Administration
O  National Telecommunications and Information Administration
The National Institutes of Health participates in some interagency working 
group activities, as well.
The 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. The FCC relies on the FDA and other health agencies for safety 
questions about wireless phones.
The 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 subject of the 
safety questions discussed in this document.
3. What kinds of phones are the subject of this update?
The term “wireless phone” refers here to handheld 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 (RF) energy because of the short distance between the phone 
and the user’s head.  
						

							195Safety
These RF exposures are limited by FCC safety guidelines that were 
developed with the advice of the 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 far below the FCC safety limits.
4. 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 (RF) energy 
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 do not 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 
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.
5. What research is needed to decide whether RF exposure from 
wireless phones poses a health risk? 
						

							196Safety
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, ver y 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.
6. What is the FDA doing to find out more about the possible 
health effects of wireless phone RF?
The 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 (RF) energy. 
The FDA has been a leading participant in the World Health Organization 
International Electro Magnetic 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. 
The FDA and the Cellular Telecommunications & Internet Association 
(CTIA) have a formal Cooperative Research And Development Agreement 
(CRADA) to do research on wireless phone safety. The FDA provides the 
scientific oversight, obtaining input from experts in government, industry, 
and academic organizations. CTIA-funded research is conducted through 
contracts with independent investigators. The initial research will include 
both laboratory studies and studies of wireless phone users. The CRADA  
						

							197Safety
will also include a broad assessment of additional research needs in the 
context of the latest research developments around the world.
7. How can I find out how much Radio Frequency energy exposure 
I can get by using my wireless phone?
All phones sold in the United States must comply with Federal 
Communications Commission (FCC) guidelines that limit Radio Frequency 
(RF) energy exposures. The FCC established these guidelines in 
consultation with the FDA and the other federal health and safety agencies. 
The FCC limit for RF exposure from wireless phones is set at a Specific 
Absorption Rate (SAR) of 1.6 watts per kilogram (1.6 W/kg). The FCC limit is 
consistent with the safety standards developed by the Institute of Electrical 
and Electronic Engineering (IEEE) and the National Council on Radiation 
Protection and Measurement. The exposure limit takes into consideration 
the body’s ability to remove heat from the tissues that absorb energy from 
the wireless phone and is set well below levels known to have effects. 
Manufacturers of wireless phones must report the RF exposure level for 
each model of phone to the FCC. The FCC website (http://www.fcc.gov/
cgb/cellular.html) gives directions for locating the FCC identification number 
on your phone so you can find your phone’s RF exposure level in the online 
listing.
8. What has the FDA done to measure the Radio Frequency energy 
coming from wireless phones?
The Institute of Electrical and Electronic Engineers (IEEE) is developing a 
technical standard for measuring the Radio Frequency (RF) energy exposure 
from wireless phones and other wireless handsets with the participation and 
leadership of FDA scientists and engineers. The standard, “Recommended 
Practice for Determining the Spatial-Peak Specific Absorption Rate (SAR) in 
the Human Body Due to Wireless Communications Devices: Experimental 
Techniques”, sets forth the first consistent test methodology for measuring 
the rate at which RF is deposited in the heads of wireless phone users. 
The test method uses a tissue-simulating model of the human head. 
Standardized SAR test methodology is expected to greatly improve the 
consistency of measurements made at different laboratories on the same 
phone. SAR is the measurement of the amount of energy absorbed in  
						

							198Safety
tissue, either by the whole body or a small part of the body. It is measured 
in watts/kg (or milliwatts/g) of matter. This measurement is used to 
determine whether a wireless phone complies with safety guidelines. 
9. 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 (RF) energy. 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 does 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.
10. 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 (RF) energy, 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.
