This device is capable of operating in Wi-Fi™
mode in the 2.4 and 5 GHz bands. The FCC
requires that devices operating within
5.15-5.25 GHz may only be used indoors, not
outside, in order to avoid interference with

Mobile Satellite Services (MSS). Therefore,
this device is restricted from being used
outdoors when operating in frequencies
between 5.15-5.25 GHz.
Exposure to Radio Frequency
(RF) Signals
The U.S. Food and Drug Administration
(FDA) has published information for
consumers relating to Radio Frequency (RF)
exposure from wireless phones.
The FDA publication includes the
following information:
Do cell phones pose a health hazard?
Many people are concerned that cell phone
radiation will cause cancer or other serious
health hazards. The weight of scientiic
evidence has not linked cell phones with
any health problems.
Cell phones emit low levels of Radio
Frequency (RF) energy. Over the past 15
years, scientists have conducted hundreds
of studies looking at the biological effects
of the radio frequency energy emitted by
cell phones. While some researchers have
reported biological changes associated
with RF energy, these studies have
failed to be replicated. The majority of
studies published have failed to show an
association between exposure to radio
frequency from a cell phone and
health problems.
The low levels of RF cell phones emit while
in use are in the microwave frequency
range. They also emit RF at substantially
reduced time intervals when in the stand-
by mode. Whereas high levels of RF can
produce health effects (by heating tissue),
exposure to low level RF that does not

8 Important Health and Safety Information Important Health and Safety Information 9
produce heating effects causes no known
adverse health effects.
The biological effects of radio frequency
energy should not be confused
with the effects from other types of
electromagnetic energy.
Very high levels of electromagnetic energy,
such as is found in X-rays and gamma rays,
can ionize biological tissues. Ionization is a
process where electrons are stripped away
from their normal locations in atoms and
molecules. It can permanently damage
biological tissues including DNA, the
genetic material.
The energy levels associated with radio
frequency energy, including both radio
waves and microwaves, are not great
enough to cause ionization of atoms and
molecules. Therefore, RF energy is a type
of non-ionizing radiation. Other types of
non-ionizing radiation include visible light,
infrared radiation (heat), and other forms
of electromagnetic radiation with relatively
low frequencies.
While RF energy does not ionize particles,
large amounts can increase body
temperatures and cause tissue damage.
Two areas of the body, the eyes and the
testes, are particularly vulnerable to RF
heating because there is relatively little
blood low in them to carry away
excess heat.
Research Results to Date: Is there a
connection between RF and certain
health problems?
The results of most studies conducted
to date say no. In addition, attempts to
replicate and conirm the few studies that
have shown a connection have failed.
The scientiic community at large therefore
believes that the weight of scientiic

8 Important Health and Safety Information Important Health and Safety Information 9
evidence does not show an association
between exposure to Radio Frequency
(RF) from cell phones and adverse health
outcomes. Still the scientiic community
has supported additional research to
address gaps in knowledge. Some of these
studies are described below.
Interphone Study
Interphone is a large international study
designed to determine whether cell
phones increase the risk of head and
neck cancer. A report published in the
International Journal of Epidemiology
(June, 2010) compared cell phone usage for
more than 5,000 people with brain tumors
(glioma and meningioma) and a similar
number of healthy controls.
Results of this study did NOT show that cell
phones caused brain cancer. In this study,
most people had no increased risk of brain
cancer from using cell phones. For people
with the heaviest use of cell phones (an
average of more than ½ hour per day, every
day, for over 10 years) the study suggested
a slight increase in brain cancer. However,
the authors determined that biases
and errors prevented any conclusions
being drawn from this data. Additional
information about Interphone can be found
at www.iarc.fr/en/media-centre/pr/2010/
pdfs/pr200_E.pdf.
Interphone is the largest cell phone study
to date, but it did not answer all questions
about cell phone safety. Additional
research is being conducted around the
world, and the FDA continues to monitor
developments in this ield.

International Cohort Study on Mobile
Phone Users (COSMOS)
The COSMOS study aims to conduct
long-term health monitoring of a large
group of people to determine if there
are any health issues linked to long-term
exposure to radio frequency energy from
cell phone use. The COSMOS study will
follow approximately 300,000 adult cell
phone users in Europe for 20 to 30 years.
Additional information about the COSMOS
study can be found at www.ukcosmos.org/

Risk of Brain Cancer from Exposure to
Radio Frequency Fields in Childhood
and Adolescence (MOBI-KIDS)
MOBI-KIDS is an international study
investigating the relationship between
exposure to radio frequency energy
from communication technologies
including cell phones and brain cancer
in young people. This is an international
multi-center study involving 14 European
and non-European countries. Additional
information about MOBI-KIDS can be found
at www.creal.cat/programes-recerca/
en_projectes-creal/view.php?ID=39.
Surveillance, Epidemiology, and End
Results (SEER) Program of the National
Cancer Institute
The National Cancer Institute (NCI) actively
follows cancer statistics in the United
States to detect any change in rates of new
cases for brain cancer. If cell phones play
a role in risk for brain cancer, rates should
go up, because heavy cell phone use has
been common for quite some time in the
U.S. Between 1987 and 2005, the overall
age-adjusted incidence of brain cancer did
not increase.
