SAFETY INFORMATION
STATEMENT OF COMPLIANCE
This device complies with part 15 of the
FCC Rules. Operation is subject to the
following two conditions: 1) This device
may not cause harmful interference, and
2) this device must accept any interfer-
ence that may cause undesired operation.
CAUTION: Changes or modifications not
expressly approved by Mitsubishi Wireless
Communications, Inc. could void your
authority from the FCC to operate the
equipment.
EXPOSURE TO RADIO
FREQUENCY SIGNALS
Your wireless handheld portable tele-
phone 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 Communica-
tions Commissions (FCC) adopted RF
exposure guidelines with safety levels for
hand-held wireless phones. These guide-
lines are consistent with the safety stan-
dards previously set by both U.S. and
international standards bodies:
*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 compre-
hensive and periodic evaluations of the
relevant scientific literature. For example,
over 120 scientists, engineers, and physi-
cians 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).
THIS MODEL PHONE MEETS THE
GOVERNMENT’SREQUIREMENTS
FOR EXPOSURE TO RADIO
WAVES.
Your wireless phone is a radio transmitter
and receiver. It is designed and manufac-
tured not to exceed the limits for
exposure to radiofrequency (RF) energy
set by the Federal Communications Com-
mission of the U.S. Government. These
limits are part of comprehensive guide-
lines and establish permitted levels of RF
energy for the general population. The
guidelines are based on 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.
The exposure standard for wireless mobile
phones employs a unit of measurement
known as the Specific Absorption Rate, or
SAR. The SAR limit set by the FCC is 1.6
W/kg.* Tests for SAR are conducted using
standard 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.
Before a phone model is available for sale
to the public, it must be tested and certi-
fied 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 highest SAR value for this
model phone when tested for use at the
ear is 0.57 W/kg and when worn on the
body, as described in this user guide, is
0.97 W/kg. (Body-worn measurements
differ among phone models, depending
upon available accessories and FCC
requirements.) While there may be differ-
ences between the SAR levels of various
phones and at various positions, they all
meet the government 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

14
phone is on file with the FCC and can be
found under the Display Grant section of
http://www.fcc.gov/oet/fccid after search-
ing on FCC ID BGB MT289.
Additional information on Specific Absorp-
tion Rates (SAR) can be found on the
Cellular Telecommunications Industry
Association (CTIA) website at http://
www.phonefacts.net.
* 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 incorpo-
rates a substantial margin of safety to give
additional protection for the public and to
account for any variations in measurements.
Your phone has been tested and meets
the limits for radio frequency (RF)
exposure set by the FCC for normal
handheld use next to the ear or worn on
the body using a Mitsubishi brand belt
clip accessory specified for this phone,
and used as intended. Operation of the
phone in other situations such as in shirt
pockets or non-Mitsubishi brand belt clips
or holsters have not been tested. There-
fore operation of the phone in non-tested
situations may not meet the limits for RF
exposure set by the FCC and must be
avoided.
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
Hold the phone as you would any other
telephone with the antenna pointed up
and over your shoulder.
For your phone to operate most effi-
ciently, extend the antenna fully (if appli-
cable) and 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 oth-
erwise needed.
DRIVING
Check the laws and regulations on the
use of wireless telephones 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 mak-
ing or answering a call if driving condi-
tions 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 Asso-
ciation recommends that a minimum sep-
aration of six (6”) inches be maintained
between a handheld wireless phone and
a pacemaker to avoid potential interfer-
ence with the pacemaker. These recom-
mendations are consistent with the
independent research by and recommen-
dations 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 pace-
maker 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 (or call the customer
service line to discuss alternatives).
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 help you obtain
this information.
Turn your phone OFF in health care facili-
ties when any regulations posted in these
areas instruct you to do so. Hospitals or
health care facilities may be using equip-

15
ment 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 regard-
ing 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.
Switch OFF your phone before boarding
an aircraft.
BLASTING AREAS
To avoid interfering with blasting opera-
tions, turn your phone OFF when in a
“blasting area” or in areas posted “Turn
off two-way radio.” Obey all signs and
instructions.
POTENTIALLY EXPLOSIVE AREAS
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
clearly marked. They include fueling areas
such as gasoline stations; below deck on
boats; fuel or chemical transfer or storage
facilities; vehicles using liquefied petro-
leum 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
AIR BAGS
An air bag inflates with great force. DO
NOT place objects, including both installed
or portable wireless equipment, in the area
over the air bag or in the air bag deploy-
ment area. If in-vehicle wireless equipment
is improperly installed and the air bag in-
flates, serious injury could result.
The U.S. Food and Drug Admin-
istration’s Center for Devices
and Radiological Health
Consumer Update on
Mobile Phones
FDA has been receiving inquiries about the
safety of mobile phones, including cellular
phones and PCS phones. The following
summarizes what is known--and what
remains unknown--about whether these
products can pose a hazard to health, and
what can be done to minimize any poten-
tial risk.
Why the concern?
Mobile phones emit low levels of radio
frequency energy (i.e., radio frequency
radiation) in the microwave range while
being used. They also emit very low levels
of radio frequency energy (RF), considered
non-significant, when in the stand-by
mode. It is well known that high levels of
RF can produce biological damage
through heating effects (this is how your
microwave oven is able to cook food).
However, it is not known whether, to what
extent, or through what mechanism,
lower levels of RF might cause adverse
health effects as well. Although some
research has been done to address these
questions, no clear picture of the biologi-
cal effects of this type of radiation has
emerged to date. Thus, the available
science does not allow us to conclude that
mobile phones are absolutely safe, or that
they are unsafe. However, the available
scientific evidence does not demonstrate
any adverse health effects associated with
the use of mobile phones.
What kinds of phones are in
question?
Questions have been raised about hand-
held mobile phones, the kind that have a
built-in antenna that is positioned close to
the user’s head during normal telephone
conversation. These types of mobile
phones are of concern because of the
short distance between the phone’s
antenna--the primary source of the RF--
and the person’s head. The exposure to RF
from mobile phones in which the antenna

16
is located at greater distances from the
user (on the outside of a car, for example)
is drastically lower than that from hand-
held phones, because a person’s RF
exposure decreases rapidly with distance
from the source. The safety of so-called
”cordless phones,” which have a base unit
connected to the telephone wiring in a
house and which operate at far lower
power levels and frequencies, has not
been questioned.
How much evidence is there that
hand-held mobile phones might be
harmful?
Briefly, there is not enough evidence to
know for sure, either way; however,
research efforts are on-going.
The existing scientific evidence is conflict-
ing and many of the studies that have
been done to date have suffered from
flaws in their research methods. Animal
experiments investigating the effects of RF
exposures characteristic of mobile phones
have yielded conflicting results. A few
animal studies, however, have suggested
that low levels of RF could accelerate the
development of cancer in laboratory ani-
mals. In one study, mice genetically
altered to be predisposed to developing
one type of cancer developed more than
twice as many such cancers when they
were exposed to RF energy compared to
controls. There is much uncertainty
among scientists about whether results
obtained from animal studies apply to the
use of mobile phones. First, it is uncertain
how to apply the results obtained in rats
and mice to humans. Second, many of the
studies that showed increased tumor
development used animals that had
already been treated with cancer-causing
chemicals, and other studies exposed the
animals to the RF virtually continuously--
up to 22 hours per day.
For the pastfive years in the United States,
the mobile phone industry has supported
research into the safety of mobile phones.
This research has resulted in two findings
in particular that merit additional study:
1. In a hospital-based, case-control study, researchers looked for
an association between mobile phone use and either glioma
(a type of brain cancer) or acoustic neuroma (a benign tumor
of the nerve sheath). No statistically significant association
was found between mobile phone use andacoustic neuroma.
There was also no associationbetween mobile phone use and
gliomas when all types of types of gliomas were considered
together.It should be noted that the average lengthofmobile
phoneexposure in thisstudy wasless thanthreeyears.
When 20 types of glioma were considered separately, how-
ever,anassociationwasfoundbetweenmobilephone useand
one rare type of glioma, neuroepithelliomatous tumors. It is
possible with multiple comparisons of the same sample that
this association occurred by chance. Moreover, the risk did not
increase with how often the mobile phone was used, or the
length of the calls. In fact, the risk actually decreased with
cumulative hours of mobile phone use. Most cancer causing
agentsincreaseriskwithincreasedexposure.Anongoingstudy
ofbrain cancers bytheNationalCancerInstituteisexpectedto
bear on theaccuracy and repeatability of these results.1
2. Researchers conducted a large battery of laboratory tests to
assess the effects of exposure to mobile phone RF on genetic
material. These included tests for several kinds of abnormali-
ties, including mutations, chromosomal aberrations, DNA
strand breaks, and structural changes in the genetic material
of blood cells called lymphocytes. None of the tests showed
any effect of the RF except for the micronucleus assay, which
detects structural effects on the genetic material. The cells in
this assay showed changes after exposure to simulated cell
phoneradiation,butonly after24hoursofexposure.It is pos-
sible that exposing the test cells to radiation for this long
resultedinheating.Sincethisassayisknown tobesensitiveto
heating, heat alone could have caused the abnormalities to
occur.Thedataalreadyin the literatureon theresponseofthe
micronucleus assay to RF are conflicting. Thus, follow-up
researchisnecessary.2
FDA is currently working with govern-
ment, industry, and academic groups to
ensure the proper follow-up to these
industry-funded research findings. Collab-
oration with the Cellular Telecommunica-
tions Industry Association (CTIA) in
particular is expected to lead to FDA pro-
viding research recommendations and sci-
entific oversight of new CTIA-funded
research based on such recommendations.
Two other studies of interest have been
reported recently in the literature:
1. Two groups of 18 people were exposed to simulated mobile
phone signals under laboratory conditions while they
performed cognitive function tests. There were no changes in
thesubjects’abilityto recallwords,numbers,orpictures,orin
their spatial memory, but they were able to make choices
more quickly in one visual test when they were exposed to
simulated mobile phone signals. This was the only change
notedamong more than20variablescompared.3
2. In a study of 209 brain tumor cases and 425 matched
controls, there was no increased risk of brain tumors
associated with mobile phone use. When tumors did exist in
certain locations, however, theywere more likely to be on the
side of the head where the mobile phone was used. Because
this occurred in only a small number of cases, the increased
likelihoodwastoosmallto be statisticallysignificant.4
In summary, we do not have enough
information at this point to assure the

17
public that there are, or are not, any low
incident health problems associated with
use of mobile phones. FDA continues to
work with all parties, including other
federal agencies and industry, to assure
that research is undertaken to provide the
necessary answers to the outstanding
questions about the safety of mobile
phones.
What is known about cases of
human cancer that have been
reported in users of hand-held
mobile phones?
Some people who have used mobile
phones have been diagnosed with brain
cancer. But it is important to understand
that this type of cancer also occurs among
people who have not used mobile phones.
In fact, brain cancer occurs in the U.S.
population at a rate of about 6 new cases
per 100,000 people each year. At that
rate, assuming 80 million users of mobile
phones (a number increasing at a rate of
about 1 million per month), about 4800
cases of brain cancer would be expected
each year among those 80 million people,
whether or not they used their phones.
Thus it is not possible to tell whether any
individual’s cancer arose because of the
phone, or whether it would have
happened anyway.
A key question is whether the risk of
getting a particular form of cancer is
greater among people who use mobile
phones than among the rest of the popu-
lation. One way to answer that question is
to compare the usage of mobile phones
among people with brain cancer with the
use of mobile phones among appropri-
ately matched people without brain
cancer. This is called a case-control study.
The current case-control study of brain
cancers by the National Cancer Institute,
as well as the follow-up research to be
sponsored by industry, will begin to
generate this type of information.
What is FDA’s role concerning the
safety of mobile phones?
Under the law, FDA does not review the
safety of radiation-emitting consumer
products such as mobile phones before
marketing, as it does with new drugs or
medical devices. However, the agency has
authority to take action if mobile phones
are shown to emit radiation at a level that
is hazardous to the user. In such a case,
FDA could require the manufacturers of
mobile 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 at this
time, FDA has urged the mobile phone
industry to take a number of steps to
assure public safety. The agency has rec-
ommended that the industry:
support needed research into possible
biological effects of RF of the type
emitted by mobile phones
design mobile phones in a way that
minimizes any RF exposure to the user
that is not necessary for device function
cooperate in providing mobile phone
users with the best possible information
on what is known about possible
effects of mobile phone use on human
health.
At the same time, FDA belongs to an inter-
agency working group of the federal
agencies that have responsibility for dif-
ferent aspects of mobile phone safety to
ensure a coordinated effort at the federal
level. These agencies are:
National Institute for Occupational
Safety and Health
Environmental Protection Agency
Federal Communications Commission
Occupational Health and Safety Admin-
istration
National Telecommunications and Infor-
mation Administration
The National Institutes of Health also
participates in this group.
In the absence of conclusive
information about any possible risk,
what can concerned individuals do?
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 people are
concerned about avoiding even potential
risks, there are simple steps they can take
to do so. For example, time is a key factor
in how much exposure a person receives.
Those persons who spend long periods of
time on their hand-held mobile phones
could consider holding lengthy conversa-
tions on conventional phones and reserv-
ing the hand-held models for shorter

18
conversations or for situations when other
types of phones are not available.
People who must conduct extended con-
versations in their cars daily could switch
to a type of mobile phone that places
more distance between their bodies and
the source of the RF, since the exposure
level drops off dramatically with distance.
For example, they could switch to a
mobile phone in which the antenna is
located outside the vehicle,
hand-held phone with a built-in
antenna connected to a different
antenna mounted on the outside of
the car or built into a separate
package, or
headset with a remote antenna to a
mobile phone carried at the waist.
Again, the scientific data do not
demonstrate that mobile phones are
harmful. But if you are concerned about
the radio frequency energy from these
products, taking the precautions outlined
above can reduce any possible risk.
