Safety
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. 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 ZNFUS550. 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
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 information
