FCC RF Exposure
Information
WARNING! Read this
information before
operating the phone.
In August 1996, the
Federal Communications
Commission (FCC) of
the United States, with
its action in Report and
Order FCC 96-326,
adopted an updated
safety standard for
human exposure to
Radio Frequency (RF)
electromagnetic energy
emitted by FCC regu-
lated transmitters. Those
guidelines are consistent
with the safety standard
previously set by both
U.S. and international
standards bodies. The
design of this phone
complies with the FCC
guidelines and these
international standards.
Bodily Contact During
Operation
This device was tested
for typical use with the
back of the phone kept
0.6 inches (1.5 cm) from
the body. To comply with
FCC RF exposure re-
quirements, a minimum
separation distance of
0.6 inches (1.5 cm) must
be maintained between
the user’s body and
the back of the phone,
including the antenna,
whether extended or
retracted. Third-party
belt-clips, holsters, and
similar accessories
containing metallic com-
ponents should not be
used. Avoid the use of
accessories that cannot
maintain 0.6 inches (1.5
cm) distance between
the user’s body and the
back of the phone and

12 | User Guide
For Your Safety
have not been tested for
compliance with FCC RF
exposure limits.
Vehicle-Mounted
External Antenna
(Optional, if available.)
To satisfy FCC RF
exposure requirements,
keep 8 inches (20 cm)
between the user /
bystander and vehicle-
mounted external
antenna. For more
information about RF
exposure, visit the FCC
website at www.fcc.gov.
Caution
Use only the supplied
antenna. Use of
unauthorized antennas
(or modifications to the
antenna) could impair
call quality, damage
the phone, void your
warranty and/or violate
FCC regulations.
Don’t use the phone with
a damaged antenna.
A damaged antenna
could cause a minor skin
burn. Contact your local
dealer for a replacement
antenna.

Consumer
Information About
Radio Frequency
Emissions
Your wireless phone,
which contains a radio
transmitter and receiver,
emits radio frequency
energy during use. The
following consumer
information addresses
commonly asked ques-
tions about the health
effects of wireless
phones.
Are wireless phones
safe?
Scientific research on
the subject of wireless
phones and radio
frequency (“RF”) energy
has been conducted
worldwide for many
years, and continues. In
the United States, the
Food and Drug Admin-
istration (“FDA”) and the
Federal Communications
Commission (“FCC”) set
policies and procedures
for wireless phones. The
FDA issued a website
publication on health
issues related to cell
phone usage where it
states, “The scientific
community at large …
believes that the weight
of scientific evidence
does not show an
association between
exposure to radiofre-
quency (RF) from cell
phones and adverse
health outcomes. Still
the scientific commu-
nity does recommend
conducting additional
research to address
gaps in knowledge.
That research is being
conducted around the

14 | User Guide
For Your Safety
world and FDA continues
to monitor develop-
ments in this field. You
can access the joint
FDA/FCC website at
http://www.fda.gov
(under “c”
in the subject index,
select Cell Phones >
Research). You can also
contact the FDA toll-free
at (888) 463-6332
or (888) INFO-FDA.
In June 2000, the
FDA entered into a
cooperative research and
development agreement
through which additional
scientific research is
being conducted. The
FCC issued its own
website publication
stating that “there is
no scientific evidence
that proves that wireless
phone usage can lead
to cancer or a variety of
other problems, includ-
ing headaches, dizziness
or memory loss.” This
publication is available at
http://www.fcc.gov/oet/
rfsafety or through the
FCC at (888) 225-5322
or (888) CALL-FCC.
What does “SAR”
mean?
In 1996, the FCC,
working with the FDA,
the U.S. Environmental
Protection Agency,
and other agencies,
established RF exposure
safety guidelines for
wireless phones in the
United States. Before a
wireless phone model is
available for sale to the
public, it must be tested
by the manufacturer
and certified to the FCC
that it does not exceed
limits established by
the FCC. One of these

15
limits is expressed as
a Specific Absorption
Rate, or “SAR.” SAR is
a measure of the rate of
absorption of RF energy
in the body. Tests for
SAR are conducted with
the phone transmitting
at its highest power level
in all tested frequency
bands. Since 1996, the
FCC has required that
the SAR of handheld
wireless phones not
exceed 1.6 watts per
kilogram, averaged over
one gram of tissue.
Although the SAR
is determined at the
highest power level, the
actual SAR value of a
wireless phone while
operating can be less
than the reported SAR
value. This is because
the SAR value may
vary from call to call,
depending on factors
such as proximity to a
cell site, the proximity of
the phone to the body
while in use, and the use
of hands-free devices.
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.
The highest SAR value
for this model phone
when tested for use
at the ear is 0.69 W/
kg and when worn on
the body, as described
in this user guide, is

16 | User Guide
For Your Safety
0.77 W/kg (body-worn
measurements differ
among phone models,
depending upon
available accessories and
FCC requirements).
While there may be dif-
ferences between 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 emission 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/ea/
fccid/ after searching on
FCC ID BEJGS505.
For more information
about SARs, see the
FCC’s OET Bulletins 56
and 65 at http://www.
fcc.gov/Bureaus/Engi-
neering_Technology/
Documents/bulletins
or visit the Cellular
Telecommunications
Industry Association
website at http://www.
ctia.org/consumer_info/
index.cfm/AID/10371.
You may also wish to
contact the manufac-
turer of your phone.

17
Can I minimize my RF
exposure?
If you are concerned
about RF, there are
several simple steps you
can take to minimize
your RF exposure. You
can, of course, reduce
your talk time. You can
place more distance
between your body and
the source of the RF,
as the exposure level
drops off dramatically
with distance. The FDA/
FCC website states that
“hands-free kits can
be used with wireless
phones for convenience
and comfort. These
systems reduce the
absorption of RF energy
in the head because
the phone, which is the
source of the RF emis-
sions, will not be placed
against the head. On the
other hand, if the phone
is mounted against the
waist or other part of the
body during use, then
that part of the body
will absorb more RF
energy. Wireless phones
marketed in the U.S. are
required to meet safety
requirements regardless
of whether they are used
against the head or
against the body. Either
configuration should
result in compliance with
the safety limit.” Also,
if you use your wireless
phone while in a car,
you can use a phone
with an antenna on the
outside of the vehicle.
You should also read
and follow your wireless
phone manufacturer’s
instructions for the safe
operation of your phone.

18 | User Guide
For Your Safety
Do wireless phones
pose any special risks
to children?
The FDA/FCC website
states that “the scientific
evidence does not show
a danger to users of
wireless communication
devices, including
children.” The FDA/FCC
website further states
that “some groups
sponsored by other na-
tional governments have
advised that children be
discouraged from using
wireless phones at all”.
For example, the Stewart
Report from the United
Kingdom [“UK”] made
such a recommendation
in December 2000. In
this report a group of
independent experts
noted that no evidence
exists that using a
cell phone causes
brain tumors or other
ill effects. [The UK’s]
recommendation to
limit cell phone use
by children was strictly
precautionary; it was
not based on scientific
evidence that any health
hazard exists. A copy
of the UK’s leaflet is
available at http://www.
dh.gov.uk (search “mo-
bile”), or you can write to:
NRPB, Chilton, Didcot,
Oxon OX11 ORQ, United
Kingdom. Copies of the
UK’s annual reports on
mobile phones and RF
are available online at
www.iegmp.org.uk and
http://www.hpa.org.
uk/radiation/ (search
“mobile”). Parents who
wish to reduce their
children’s RF exposure
may choose to restrict
their children’s wireless
phone use.
