TIA Safety Information

The following is the complete TIA Safety Information for wireless handheld
phones:

Exposure to Radio Frequency Signal

Your wireless handheld portable phone is a low-power radio transmitter and
receiver. When ON, it receives and 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, as follows:
ANSI C95.1 (1992) *
NCRP Report 86 (1986)
ICNIRP (1996)
* American National Standards Institute; National Council on Radiation
Protection and Measurements; International Commission on Non-Ionizing
Radiation Protection. 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). The design of your phone complies with the FCC
guidelines (and those standards).

Antenna Care

Use only the supplied or 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 operating the phone. Contact with the antenna affects call
quality and may cause the phone to operate at a higher power level than
otherwise needed, thus reducing battery life.

Driving

Always observe the laws and regulations regarding wireless phone usages
while driving. Where cell phone use is permitted while driving, you MUST
observe the following:

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

2. Use hands-free operation, if available;

3. Pull off the road and park before making or answering a call if driving
conditions or the law requires that you do so.

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:

1. Should ALWAYS keep the phone more than six (6) inches from their
pacemaker when the phone is turned ON;

2. Should not carry the phone in a breast pocket;

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

4. Should turn the phone OFF immediately if there is any reason to suspect
that interference is occurring.

Electronic Devices

Most modern electronic equipment is shielded from RF signals but some
equipment or devices might not be.

Hearing Aids

Some digital wireless phones may interfere with hearing aids. In the event of
such interference, you please consult your service provider, or call customer
service regarding alternatives.

Other Medical Devices

If you use other personal medical devices, consult the device manufacturer to
determine if it is adequately shielded from external RF energy, or your health
care provider may be able to advice about any harmful device interactions.

Vehicles

RF signals may affect improperly installed or inadequately shielded electronic
systems in motor vehicles. Be certain to contact the manufacturer or
representative regarding this as well as manufacturer of any additional vehicle
equipment.

Posted Facilities

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

For Vehicles Equipped with an Air Bag

DO NOT place objects, including 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

8. When using the phone in public places, set the ringtone to vibration so
you don't disturb others.

9. Do not turn your phone on or off while the device is in close proximity to
your ear.

10. Use accessories, such as earphones and headsets with caution. Ensure
that cables are tucked away safely and do not touch the antenna.

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
hearing loss. This includes the use of headphones (including headsets, ear
buds and Bluetooth®, or other wireless devices). Exposure to very loud sound
has also been associated in some studies with tinnitus (ringing in the ear),
hypersensitivity to sound, and distorted hearing. 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. Hence, individual
susceptibility to noise-induced hearing loss and other hearing problems can
vary. Please follow these important guidelines for hearing loss prevention:

1. Set the phone’s volume in a quiet environment and select the lowest
volume for which you can hear clearly.

2. 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.

3. Do not turn the volume up to block out noisy surroundings. If you choose
to listen to your portable device in a noisy environment, consider using
noise-cancelling headphones to block out background noise.

4. As the volume increases, less time is required before your hearing could
be affected, so consider limiting your listening time.

5. Avoid using headphones after exposure to extremely loud noises (e.g.: live
concerts) that might cause temporary hearing loss which, in turn, might cause
unsafe volume levels to sound like normal levels.

6. 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 health care provider.

FDA Consumer Update

The U.S. Food and Drug Administration’s (FDA) Center for Devices and
Radiological Health Consumer Update on Mobile Phones:

1. 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:

1. Support current and future research regarding possible biological effects
of the type of RF emitted by wireless phones;

2. Design wireless phones in a way that minimizes any RF exposure to the
user that is not necessary for device function; and

3. Cooperate in providing users of wireless phones with complete and
accurate information regarding possible effects of wireless phone use on
human health and safety.
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:

1. National Institute for Occupational Safety and Health

2. Environmental Protection Agency

3. Occupational Safety and Health Administration

4. 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 act
to 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.

2. Do wireless phones pose a health hazard?

Current 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 while operating microwave ranges (which also emit
very low levels of RF when they are in standby mode). While high levels of RF
can produce health effects (by heating tissue), exposure to low-level RF that
does not produce heating effects results in no known adverse health effects.
Many studies of low-level RF exposures have not uncovered any biological
effects. Although some studies have suggested that some biological effects
may occur, such findings have not been confirmed by additional research. In
some cases, other researchers have had difficulty in reproducing those
studies, and/or determining the reasons for inconsistent results.

3. What are the results of the research done already?

The research conducted 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 it is

largely unknown what the results of such studies mean for human health and
safety. Three large epidemiology studies have been published since December

2000. These studies investigated possible associations between the use of
wireless phones and primary brain cancer (glioma, meningioma, acoustic
neuroma, other brain tumors, and salivary gland tumors), leukemia, or other
types of cancer. None of the studies demonstrated the existence of any
harmful health effects from wireless phone RF exposures. However, none of
the studies can provide absolute findings about long-term exposures since the
average period of phone use in these studies was approximately three years.

4. What kinds of phones are the subjects of this update?

Here the term “wireless phone” refers 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.
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 reduced due to a person's RF exposure rapidly decreasing
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, thus
producing RF exposures far below the FCC safety limits.

5. 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 concerns 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 implemented new research programs
around the world. The project has also resulted in 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 conduct 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.

6. 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 vital data. Lifetime
animal exposure studies could be completed in a few years. However, very
large numbers of animals would be needed to provide reliable proof of a
cancer-promoting effect, if one exists. Epidemiological studies can provide
data that is directly applicable to human populations, but ten or more years of
follow-up research may be needed to provide answers about certain health
effects, such as cancer.
This is due to the interval between exposure time to a cancer-causing agent
and the rate for which tumors develop - if they do. This could take several
years into the future. 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.

7. 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 tissue, either by the whole
body or a small part of the body. It is measured in watts/kg (or mill-watts/g)
of matter. This measurement is used to determine whether a wireless phone
complies with safety guidelines.

8. 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 (1.6W/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.

9. 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.

10. 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 on a daily basis, consider placing 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.

11. What about wireless phone interference with medical equipment?

Radio Frequency (RF) energy from wireless phones can interact with some
electronic devices. For this reason, the FDA helped develop a detailed test
method to measure Electro Magnetic 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 manufacturers to ensure that cardiac

pacemakers and defibrillators are safe from wireless phone EMI. The 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 simultaneously. This standard was approved by the
IEEE in 2000. The FDA continues to monitor the use of wireless phones for
possible interactions with other medical devices. Should harmful interference
be found to occur, the FDA will conduct testing to assess the interference and
work to resolve the problem.

Consumer Information on SAR

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
radiofrequency (RF) energy set by the Federal Communications Commission
(FCC) of the U.S. Government. These FCC exposure limits are derived from the
recommendations of two expert organizations, the National Council on
Radiation Protection and Measurement (NCRP) and the Institute of Electrical
and Electronics Engineers (IEEE). In both cases, the recommendations were
developed by scientific and engineering experts drawn from industry,
government, and academia after extensive reviews of the scientific literature
related to the biological effects of RF energy. The exposure limit for wireless
mobile phones employs a unit of measurement known as the Specific
Absorption Rate, or SAR. The SAR is a measure of the rate of absorption of RF
energy by the human body expressed in units of watts per kilogram (W/kg).
The FCC requires wireless phones to comply with a safety limit of 1.6 watts per
kilogram (1.6 W/kg). The FCC exposure limit incorporates a substantial margin
of safety to give additional protection to the public and to account for any
variations in measurements. Tests for SAR 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. Although 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. Because the
phone is designed to operate at multiple power levels to use only the power
required to reach the network, generally, the closer you are to a wireless base
station antenna, the lower the power output. Before a phone model 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. This device was tested for typical body-worn
operations with the back of the phone kept 0.39 inches (1.0 cm) between the
user’s body and the back of the phone. To comply with FCC RF exposure
requirements, a minimum separation distance of 0.39 inches (1.0 cm) must be
maintained between the user's body and the back of the phone. Third-party
belt clips, holsters, and similar accessories containing metallic components
should not be used.
Body-worn accessories that cannot maintain 0.39 inches (1.0 cm) separation
distance between the user's body and the back of the phone, and have not
been tested for typical body-worn operations may not comply with FCC RF
exposure limits and should be avoided.
The FCC has granted an Equipment Authorization for this model phone with
all reported SAR levels evaluated as in compliance with the FCC RF emission
guidelines.

The highest SAR value for this model phone when tested for use at the ear is

0.599 W/kg and when worn on the body, as described in this user’s manual,
is 1.429 W/kg. While there may be differences between SAR levels of
various phones and at various positions, they all meet the government
requirement for safe exposure.

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/ea/fccid/ after
searching on FCC ID: R38YL3310A.
To find information that pertains to a particular model phone, this site uses the
phone FCC ID number which is usually printed somewhere on the case of the
phone. Sometimes it may be necessary to remove the battery pack to find the
number. Once you have the FCC ID number for your phone, follow the
instructions on the website and it should provide values for typical or
maximum SAR for that phone.
Additional information on Specific Absorption Rates (SAR) can be found on
the Cellular Telecommunications Industry Association (CTIA) website at
http://www.ctia.org/
In the United States 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.

FCC Hearing-Aid Compatibility (HAC) Regulations for Wireless Devices

On July 10, 2003, the U.S. Federal Communications Commission (FCC) Report
and Order in WT Docket 01- 309 modified the exception of wireless phones
under the Hearing Aid Compatibility Act of 1988 (HAC Act) to require digital
wireless phones be compatible with hearing-aids. The intent of the HAC Act is
to ensure reasonable access to telecommunications services for persons with
hearing disabilities. While some wireless phones are used near some hearing
devices (hearing aids and cochlear implants), users may detect a buzzing,
humming, or whining noise. Some hearing devices are more immune than
others to this interference noise, and phones also vary in the amount of
interference they generate. The wireless telephone industry has developed a
rating system for wireless phones, to assist hearing device users to find
phones that may be compatible with their hearing devices. Not all phones
have been rated. Phones that are rated have the rating on their box or a label
located on the box. The ratings are not guarantees. Results will vary
depending on the user's hearing device and hearing loss. If your hearing
device happens to be vulnerable to interference, you may not be able to use a
rated phone successfully. Trying out the phone with your hearing device is the
best way to evaluate this.
M-Ratings: Phones rated M3 or M4 meet FCC requirements and are likely to
generate less interference to hearing devices than phones that are not labeled.
M4 is the better/higher of the two ratings.
T-Ratings: Phones rated T3 or T4 meet FCC requirements and are likely to
generate less interference to hearing devices than phones that are not labeled.
T4 is the better/ higher of the two ratings.
Hearing devices may also be rated. Your hearing device manufacturer or
hearing health professional may help you find this rating. Higher ratings mean
that the hearing device is relatively immune to interference noise. The hearing
aid and wireless phone rating values are then added together. A sum of 5 is
considered acceptable for normal use. A sum of 6 is considered for best use.
In the example illustrated above, if a hearing aid meets the M2 level rating and
the wireless phone meets the M3 level rating, the sum of the two values equal
M5. This should provide the hearing-aid user with “normal usage” while using
their hearing aid with the particular wireless phone. “Normal usage” in this
context is defined as a signal quality that’s acceptable for normal operation.
The M mark is intended to be synonymous with the U mark. The T mark is
intended to be synonymous with the UT mark. The M and T marks are
recommended by the Alliance for Telecommunications Industries Solutions
(ATIS). The U and UT marks are referenced in Section 20.19 of the FCC Rules.
The HAC rating and measurement procedure are described in the American
National Standards Institute (ANSI) C63.19 standard.
When you're talking on a cell phone, it's recommended that you turn the BT
(Bluetooth) mode off for HAC.
