Safety Guidelines

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).

11

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.

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.

12

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.

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.

13

Aircraft

FCC regulations prohibit using your phone while in the air. Turn your phone

OFF before boarding an aircraft.

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.

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 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.

17

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

18

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

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

19

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
