FCC RF Exposure Information

WARNING!

Read this information before operating the phone.

In August 1996, the Federal Communications Commission (FCC) of the United States, with its action in Report

and Order FCC 96-326, adopted an updated safety standard for human exposure to radio frequency (RF)

electromagnetic energy emitted by FCC regulated transmitters. Those guidelines are consistent with the safety

standard previously set by both U.S. and international standards bodies.

The design of this phone complies with the FCC guidelines and these international standards.

CAUTION

Use only the supplied and approved antenna. Use of unauthorized antennas or modifications could impair call

quality, damage the phone, void your warranty and/or result in violation of FCC regulations. Do not use the phone

with a damaged antenna. If a damaged antenna comes into contact with skin, a minor burn may result. Contact

your local dealer for a replacement antenna.

Body-worn Operation

This device was tested for typical body-worn operations with the back of the phone kept 1 cm (0.39 inches)

between the user’s body and the back of the phone. To comply with FCC/IC RF exposure requirements, a

minimum separation distance of 1 cm (0.39 inches) must be maintained between the user’s body and the back

of the phone.

7

Third-party belt-clips, holsters, and similar accessories containing metallic components may not be used.

Body-worn accessories that cannot maintain 1 cm (0.39 inches) separation distance between the user’s body and the

back of the phone, and have not been tested for typical bodyworn operations may not comply with FCC/IC RF exposure

limits and should be avoided.

TIA Safety Information

Provided herein is the complete TIA Safety Information for Wireless Handheld phones. Inclusion of the text

covering Pacemakers, Hearing Aids, and Other Medical Devices is required in the owner’s manual for CTIA

Certification. Use of the remaining TIA language is encouraged when appropriate.

Exposure to Radio Frequency Signal

Your wireless handheld portable telephone is a low power radio transmitter and receiver. When it is ON, it

receives and also sends out radio frequency (RF) signals. In August, 1996, the Federal Communications

Commissions (FCC) adopted RF exposure guidelines with safety levels for handheld wireless phones.

Those guidelines are consistent with the safety standards previously set by both U.S. and international standards

bodies:

ANSI C95.1 (1992) *

NCRP Report 86 (1986)

ICNIRP (1996)

Those standards were based on comprehensive and periodic evaluations of the relevant scientific literature. For

example, over 120 scientists, engineers, and physicians from universities, government health agencies, and

industry reviewed the available body of research to develop the ANSI Standard (C95.1).

* American National Standards Institute; National Council on Radiation Protection and Measurements;

International Commission on Non-Ionizing Radiation Protection

The design of your phone complies with the FCC guidelines (and those standards).

Antenna Care

Use only the supplied or an approved replacement antenna. Unauthorized antennas, modifications, or attachments

could damage the phone and may violate FCC regulations.

Phone Operation

NORMAL POSITION: Hold the phone as you would any other telephone with the antenna pointed up and over

your shoulder.

Safety Guidelines

10

Tips on Efficient Operation

For your phone to operate most efficiently:

• Do not touch the antenna unnecessarily when the phone is in use. Contact with the antenna affects call quality

and may cause the phone to operate at a higher power level than otherwise needed.

Driving

Check the laws and regulations on the use of wireless phones in the areas where you drive. Always obey them.

Also, if using your phone while driving, please:

• Give full attention to driving - driving safely is your first responsibility;

• Use hands-free operation, if available;

• Pull off the road and park before making or answering a call if driving conditions so require.

Electronic Devices

Most modern electronic equipment is shielded from RF signals.

However, certain electronic equipment may not be shielded against the RF signals from your wireless phone.

Pacemakers

The Health Industry Manufacturers Association recommends that a minimum separation of six (6”) inches

be maintained between a handheld wireless phone and a pacemaker to avoid potential interference with the

pacemaker.

These recommendations are consistent with the independent research by and recommendations of Wireless

Technology Research. Persons with pacemakers:

• Should ALWAYS keep the phone more than six inches from their pacemaker when the phone is turned ON;

• Should not carry the phone in a breast pocket.

• Should use the ear opposite the pacemaker to minimize the potential for interference.

• If you have any reason to suspect that interference is taking place, turn your phone OFF immediately.

11

Hearing Aids

Some digital wireless phones may interfere with some hearing aids. In the event of such interference, you may

want to consult your service provider.

Other Medical Devices

If you use any other personal medical device, consult the manufacturer of your device to determine if they

are adequately shielded from external RF energy. Your physician may be able to assist you in obtaining this

information.

Health Care Facilities

Turn your phone OFF in health care facilities when any regulations posted in these areas instruct you to do so.

Hospitals or health care facilities may use 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.

Posted Facilities

Turn your phone OFF in any facility where posted notices so require.

Aircraft

FCC regulations prohibit using your phone while in the air. Turn your phone OFF before boarding an aircraft.

12

Blasting Areas

To avoid interfering with blasting operations, turn your phone OFF when in a ‘blasting areas or in areas posted:

‘Turn off two-way radio’. Obey all signs and instructions.

Potentially Explosive Atmosphere

Turn your phone OFF 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.

Areas with a potentially explosive atmosphere are often, but not always, marked clearly. Potential areas may

include: fueling areas (such as gasoline stations); below deck on boats; fuel or 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.

For Vehicles Equipped with an Air Bag

An air bag inflates with great force. DO NOT place objects, including either installed or portable wireless

equipment, in the area over the air bag or in the air bag deployment area. If in-vehicle wireless equipment is

improperly installed and the air bag inflates, serious injury could result.

Safety Information

Please read and observe the following information for safe and proper use of your phone and to prevent damage.

Also, keep the user guide in an accessible place at all times after reading it.

Charger and Adapter Safety

• The charger and adapter are intended for indoor use only.

13

Battery Information and Care

• Please dispose of your battery properly or take it to your local wireless carrier for recycling.

• The battery does not need to be fully discharged before recharging.

• Use only LG-approved chargers specific to your phone model since they are designed to maximize battery life.

• Do not disassemble or impact the battery as it may cause electric shock, short-circuit, and fire. Store the

battery in a place out of reach of children.

• Replace the battery when it no longer provides acceptable performance. The battery can be recharged several

hundred times before replacement.

• Recharge the battery after long periods of non-use to maximize battery life.

• Battery life will vary due to usage patterns and environmental conditions.

• Use of extended backlighting, Media Net Browsing, and data connectivity kits affect battery life and talk/

standby times.

• Actual battery life will depend on network configuration, product settings, usage patterns, battery and

environmental conditions.

• Always unplug the charger from the wall socket after the phone is fully charged to save unnecessary power

consumption of the charger.

Explosion, Shock, and Fire Hazards

• 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.

• Unplug the power cord prior to cleaning your phone, and clean the power plug pin when it is dirty.

• When using the power plug, ensure that it is firmly connected. If it is not, it may cause excessive heat or fire.

• 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 shortcircuit the phone. Always cover the receptacle

when not in use.

• Do not 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-circuiting of

the terminal may damage the battery and cause an explosion.

14

General Notice

• Using a damaged battery or placing a battery in your mouth may cause serious injury.

• 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.

• Talking on your phone for a long period of time may reduce call quality due to heat generated during use.

• When the phone is not used for a long period time, store it in a safe place with the power cord unplugged.

• Using the phone in proximity to receiving equipment (i.e., TV or radio) may cause interference to the phone.

• 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 Centre to replace the damaged antenna.

• 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 Centre.

• Do not paint your phone.

• The data saved in your phone might be deleted due to careless use, repair of the phone, or upgrade of

battery which should be replaced only by LG or an authorized LG repair centre. You should never attempt to

open or disassemble this device yourself and doing so may cause damage that will void your warranty.

FDA Consumer Update

The U.S. Food and Drug Administration Centre 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 energy (RF) in the microwave range while being used. They also emit very low levels of RF when

in the standby mode. Whereas high levels of RF can produce health effects (by heating tissue), exposure to low

15

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 energy (RF) 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 do not justify FDA regulatory actions, the 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 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:

• National Institute for Occupational Safety and Health

• Environmental Protection Agency

• Occupational Safety and Health Administration (Administración de la seguridad y salud laborales)

• Occupational Safety and Health Administration

• 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.

16

3. What kinds of phones are the subject of this update?

The term ‘wireless phone’ refers here to handheld wireless phones with builtin antennas, often called ‘cell’,

‘mobile’, or ‘PCS’ phones. These types of wireless phones can expose the user to measurable radiofrequency

energy (RF) because of the short distance between the phone and the user’s head. 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 radiofrequency 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 predisposed 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, 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 longterm 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?

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.

17

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 radiofrequency energy (RF). The 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. 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 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 radiofrequency 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 radiofrequency energy (RF) 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 telephones

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/oet/rfsafety) 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 radiofrequency energy coming from wireless phones?

The Institute of Electrical and Electronic Engineers (IEEE) is developing a technical standard for measuring the

radiofrequency energy (RF) 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

tissue, either by the whole body or a small part of the body. It is measured in watts/kg (or milliwatts/g) of matter.

18

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 radiofrequency 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 radiofrequency 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. 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 radiofrequency 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.

11. What about wireless phone interference with medical equipment?

Radiofrequency energy (RF) from wireless phones can interact with some electronic devices. For this reason, the

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 the FDA,

medical device manufacturers, and many other groups, was completed in late 2000. This standard will allow
