USING THIS GUIDE
Your dual band/dual mode T300 phone operates on PCS 800 MHz
digital/analog and 1900 MHz digital networks. Digital systems provide
improved voice quality as well as security and privacy. Dual mode means
that if you travel to an area without digital service, your phone will
transfer to an analog system with no gap in your connection.
Certain features included in this guide called Network services are
supplied by wireless service providers. Before you can activate or use any
of these Network services, you must subscribe to the services from your
home service provider. For a full list and explanation of Network
services, please ask your service provider.
One of the most versatile features of the T300 phone are the softkey
functions. They provide immediate access to the actions you are most
likely to do next, depending on what you are currently doing. If you are
dialing a phone number, the Options softkey brings you directly to
options such as storing the number or placing a 1 before the number for
long distance dialing without fumbling through menus. Softkey actions

SAFETY INFORMATION
EXPOSURE TO RADIO
FREQUENCY SIGNALS
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
hand-held wireless phones. These 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)
*American National Standards Institute;
National Council on Rad iation Protection and
Measurements; Inter national Commission on
Non-Ionizing Radia tion 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).
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 limits for exposure
to radiofrequency (RF) energy set by the
Federal Communications Commission of
the U.S. Government. These limits are part
of comprehensive guidelines 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 certified to the FCC that it does not exceed the
limit established by the governmentadopted 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 as reported
to the FCC for this model phone when
tested for use at the ear is 1.35 and when
worn on the body, as described in this user
guide, is 0.51. (Body- worn measurements
differ among phone models, depending
upon available accessories and FCC requirements.) While there may be differences
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
phone is on file with the FCC and can be
found under the Display Grant section of
http://www.fcc.gov/oet/fccid after searching on FCC ID BGB MT345.
Additional information on Specific Absorption 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
13
public is 1.6 watts/kilogram (W/kg)
averaged over one gram of tissue. The
standard incorporates a substantial
margin of safety to give additional protection for the publ ic 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. Therefore 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 efficiently, extend the antenna fully (if applicable) 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 otherwise 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 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.
Pace make rs
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
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 facilities when any regulations posted in these
areas instruct you to do so. Hospitals or
health care facilities may be using equipment that could be sensitive to external RF
energy.
Vehicle s
RF signals may affect improperly installed
or inadequately shielded electronic
systems in motor vehicles. Check with the
manufacturer or its representative regard-
14
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 inter fering with blasting operations, 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 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
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 deployment area. If in-vehicle wireless equipment
is improperly installed and the air bag inflates, serious injury could result.
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 interference
that may cause undesired operation.
The U.S. Food and Drug Administration’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 potential 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 th e 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 biological 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
any adverse health effects associated with
the use of mobile phones.
What kinds of phones are in
question?
Questions have been raised about handheld 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 w hich the antenna
is located at greater distances from the
user (on the outside of a car, for example)
demonstrate
15
is drastically lower than that from handheld 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 conflicting 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 animals. 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 past five 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 ne uroma (a benign tumor
of the nerve sheath). No statistically significant association
was found between mobile phone use and acoustic neuroma.
There was also no association between mobile phone use and
gliomas when all types of gliomas were considered together.
It should be noted that the average length of mobile phone
exposure in this study was less than three years.
When 20 types of glioma were considered separately, however, an association was found between mobile phone use and
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
agents increase risk with increased exposure. An ongoing study
of brain cancers by the National C ancer Institute is expected to
bear on the accuracy and rep eatability of these results.
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 abnormalities, 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
phone radiation, but only after 24 hours of exposure. It is possible that exposing the test cells to radiation for this long
resulted in heating. Since this assay is known to be sensitive to
heating, heat alone could have caused the abnormalities to
occur. The data already in the literature on the response of the
micronucleus assay to RF are conflicting. Thus, follow-up
research is necessary.
FDA is currently working with government, industry, and academic groups to
ensure the proper follow-up to these
industry-funded research findings. Collaboration with the Cellular Telecommunications Industry Association (CTIA) in
particular is expected to lead to FDA providing research recommendations and scientific 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
the subjects’ ability to recall words, numbers, or pictures, or in
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
noted among more than 20 variables compared.
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, they were 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
likelihood was too small to be statistically significant.
In summary, we do not have enough
information at this point to assure the
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 population. 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 appropriately matched people without brain
cancer. This is called a case-control study.
The current case-control study of brain
cancers by the National Ca ncer 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 radia tion 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 recommended that the industry:
n support needed research into possible
biological effects of RF of the type
emitted by mobile phones
n design mobile phones in a way that
minimizes any RF exposure to the user
that is not necessary for device function
n 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 interagency working group of the federal
agencies that have responsibility for different aspects of mobile phone safety to
ensure a coordinated effort at the federal
level. These agencies are:
n National Institute for Occupational
Safety and Health
n Environmental Protection Agency
n Federal Communications Commission
n Occupational Health and Safety Admin-
istration
n 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 conversations on conventional phones and reserving the hand-held models for shorter
conversations or for situations when other
types of phones are not available.
17
People who must conduct extended conversations in their cars daily could switch
to a type of mobile phone that places
more distance between their bodies and
the source of th e RF, since the exposure
level drops off dramatically with distance.
For example, they could switch to a
n mobile phone in which the antenna is
located outside the vehicle,
n 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
n 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.
