Operational Cautions
Do not operate any battery charger if it has received a sharp blow, has been
dropped, or has been damaged in any way; take it to a qualified service
technician.
Do not disassemble a battery charger; take it to a qualified service
technician when service or repair is required. Incorrect reassembly may
result in a risk of electric shock or fire.
Maximum ambient temperature around the power supply or transformer of
any battery charger should not exceed 40°C (104°F).
The output power from the power supply or transformer must not exceed
the rating given on the Desktop Dual-Pocket Charger.
The disconnection from the line voltage is made by unplugging the power
supply from the AC receptacle.
To reduce risk of electric shock, unplug any battery charger from the outlet
before attempting any maintenance or cleaning.
For optimum charging performance, turn off the radio product while charging it
in any battery charger.

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. This information
may be used to respond to questions.
Why the concern?
Mobile phones emit low levels of radiofrequency energy (i.e., radiofrequency
radiation) in the microwave range while being used. They also emit very low
levels of radiofrequency 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 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
evidencedoes notdemonstrate 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 users head during normal
telephone conversation. These types of mobile phones are of concern because of
the short distance between the phones antenna--the primary source of the RF--
and the persons head. The exposure to RF from mobile phones in which the
antenna 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
persons 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.

US FDA Consumer Update
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
twiceasmanysuchcancerswhentheywereexposedtoRFenergycomparedto
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 neuroma (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 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 actuallydecreasedwith
cumulative hours of mobile phone use. Most cancer causing agents
increase risk with increased exposure. An ongoing study of brain cancers
by the National Cancer Institute is expected to bear on the accuracy 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 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.(2)
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.(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, they were more likely to be
on the side of the head where the mobile phone was used. Because this 
						

							207
US FDA Consumer Update
occurred in only a small number of cases, the increased likelihood was too
small to be statistically significant.(4)
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 individuals 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 Cancer
Institute, as well as the follow-up research to be sponsored by industry, will
begin to generate this type of information.
What is FDAs 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 recommended that the industry: 
						

							208
90

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; and
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:
National Institute for Occupational Safety and Health
Environmental Protection Agency
Federal Communications Commission
Occupational Health and Safety Administration
National Telecommunications and Information 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.
People who must conduct extended conversations in their cars every day 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,
a 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
a headset with a remote antenna to a mobile phone carried at the waist.

US FDA Consumer Update
Again, the scientific datado notdemonstrate that mobile phones are harmful.
But if people are concerned about the radiofrequency energy from these
products, taking the simple precautions outlined above can reduce any possible
risk.
