Safety Guidelines
(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 for wireless mobile
phones employs a unit of measurement known as the
Specific Absorption Rate, or 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. Tests for
SAR are conducted using standard operating positions
specified by the FCC with the phone transmitting at
its highest certified power level in all tested frequency
bands. Although 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.
Because the phone is designed to operate at multiple
power levels 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 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 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.
The highest SAR value for this model phone when
tested for use at the ear is 0.47 W/kg and when worn
on the body, as described in this user’s manual, is 0.56
W/kg. While there may be differences between SAR
levels of various phones and at various positions, they
all meet the government requirement for safe exposure.
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 ZNFB460.
To find information that pertains to a particular model
phone, this site uses the phone FCC ID number which
is usually printed somewhere on the case of the phone.
Sometimes it may be necessary to remove the battery
pack to find the number. Once you have the FCC ID
