Section 4A: Safety 131
Health and Safety Information
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. Body-worn operations are
restricted to Samsung-supplied, approved, or non-Samsung designated accessories
that have no metal and must provide at least 1.5 cm separation between the device,
including its antenna (whether extended or retracted) and the user's body. Non-
compliance with the above restrictions may result in violation of FCC RF exposure
guidelines.
The FCC has granted an Equipment Authorization for this mobile phone with all
reported SAR levels evaluated as in compliance with the FCC RF exposure guidelines.
The maximum SAR values for this model phone as reported to the FCC are:
AMPS mode (Part 22):
Head: 1.36 W/kg; Body-worn: 0.923 W/kg
PCS mode (Part 24):
Head: 0.88 W/kg; Body-worn: 0.667 W/kg
