Exposure to Radio Frequency (RF) Signals
Certification Information (SAR)
Your wireless phone is a radio transmitter and receiver.
It is designed and manufactured not to exceed the
exposure limits for radio frequency (RF) energy set by
the Federal Communications Commission (FCC) of the
U.S. government. These FCC exposure limits are derived
from the recommendations of two expert organizations,
the National Counsel on Radiation Protection and
Measurement (NCRP) and the Institute of Electrical
and Electronics Engineers (IEEE). In both cases, the
recommendations were developed by scientific and
engineering experts drawn from industry, government,
and academia after extensive reviews of the scientific
literature related to the biological effects of RF energy.
The exposure limit set by the FCC for wireless mobile
phones employs a unit of measurement known as the
Specific Absorption Rate (SAR). The SAR is a measure of
the rate of absorption of RF energy by the human body
expressed in units of watts per kilogram (W/kg). The FCC
requires wireless phones to comply with a safety limit
of 1.6 watts per kilogram (1.6 W/kg). The FCC exposure
limit incorporates a substantial margin of safety to give
additional protection to the public and to account for
any variations in measurements.
SAR tests 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 new model phone is available for sale to the
public, it must be tested and certified to the FCC that
it does not exceed the exposure limit established by
the FCC. Tests for each model phone are performed in
positions and locations (e.g. at the ear and worn on the
body) as required by the FCC.
Health and safety information
The highest SAR values for this model phone as
reported to the FCC are Head: 0.584W/Kg, Body-worn:
0.344W/Kg.
For body worn operations, this model phone has been
testde and meets the FCC exposure guidelines when
used with a Samsung accessory designated for this
product or when used with an accessroy that contains
no metal and that positons the handset a minimum 1.5
cm from the body.
Non-compliance with the above restrictions may result in
violation of FCC RF exposure guidelines.
SAR information on this and other model phones can be
viewed on-line at www.fcc.gov/oet/fccid. This site uses
the phone FCC ID number
A3LSCH-W240
.
Sometimes it may be necessary to remove the battery
pack to find the number. Once you have the FCC ID
number for a particular phone, follow the instructions
on the website and it should provide values for typical or
maximum SAR for a particular phone. Additional product
specific SAR information can also be obtained at www.

Consumer Information on
Wireless Phones
The U.S. Food and Drug Administration (FDA) has
published a series of Questions and Answers for
consumers relating to radio frequency (RF) exposure
from wireless phones. The FDA publication includes the
following information:
What kinds of phones are the subject of this
update?
The term wireless phone refers here to hand-held
wireless phones with built-in antennas, often called “cell,”
“mobile,” or “PCS” phones. These types of wireless phones
can expose the user to measurable radio frequency
energy (RF) because of the short distance between
the phone and the user’s head. These RF exposures are
limited by Federal Communications Commission safety
guidelines that were developed with the advice of FDA
and other federal health and safety agencies. When the
phone is located at greater distances from the user, the
exposure to RF is drastically lower because a person’s RF
