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. For body worn operation, this phone has been tested and meets FCC
RF exposure guidelines when used with an accessory that contains no metal and that positions
the handset a minimum of 1.5 cm from the body. Use of other accessories may not ensure
compliance with 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:
