Samsung SGH SPH-I550 User Manual page 18

The standards include a substantial safety margined designed to assure the safety of all
persons, regardless of age and health.
The exposure standard for wireless mobile phones employs a unit of measurement
known as the Specific Absorption Rate, or SAR. The SAR limit set by the FCC is 1.6W/kg *.
SAR tests 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 the SAR is determined at the highest certified power level, the actual SAR
level of the phone while operation 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 output of the phone.
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 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. While there may be differences between the SAR levels of various phones and
at various positions, they all meet the government requirement.
The FCC has granted an Equipment Authorization for this model phone with all reported
SAR levels evaluated as in compliance with the FCC RF exposure 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/fccid after searching on FCC ID
printed in the label on the phone.
*In the U.S. and Canada, the SAR limit for mobile phones used by the public is 1.6
watts/kg (W/kg) averaged over one gram of tissue. The standard incorporates a
substantial margin of safety to give additional protection for the public and to account
for any variations in measurements.
