Samsung Galaxy Note 4 Important Information Manual page 8

The RF 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 SAR 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 reported 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 of the device.
Before a new model device is available for
sale to the public, it must be tested and
certified to the FCC that it does not exceed
the SAR 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.
For body-worn operation, this device has
been tested and meets FCC RF exposure
guidelines when used with an accessory
that contains no metal and that positions
