Polycom SpectraLink 8400 Series Wireless Handset

In the United States and Canada, the SAR limit for mobile handsets 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.
The FCC conducts tests for SAR using standard operating positions specified by the FCC with the handset
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 handset while operating can
be well below the maximum value. This is because the handset is designed to operate at multiple power
levels so that it uses only the power required to reach the network. Before a handset model is available
for sale to the public, the FCC must test and certify it to ensure that phones do not exceed the limit
established by the government-adopted requirement for safe exposure. The tests are performed in
positions and locations (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 handsets and at various positions, they all
meet the government requirement for safe exposure.
The FCC has granted an Equipment Authorization for this model handset with all reported SAR levels
evaluated in compliance with the FCC RF emission guidelines.
SAR information on this model handset is on file with the FCC. You can find it under the Display Grant
section at
http://www.fcc.gov/oet/ea after searching on the FCC ID number found on the handset label
inside the battery compartment. Additional information on Specific Absorption Rates (SAR) can be found
on the Cellular Telecommunications Industry Association (CTIA) Website at
