2ALNA-BTS56Wireless Party Speaker

SAR Information Statement Your Wireless Party Speaker is a radio transmitter and receiver. It is designed and manufactured not to exceed the emission limits for exposure to radiofrequency (RF) energy set by the Federal Communications Commission of the U.S. Government. These limits are part of comprehensive guidelines and establish permitted levels of RF energy for the general population. The guidelines are based on standards that were developed by independent scientific organizations through periodic and thorough evaluation of scientific studies. The standards include a substantial safety margin designed to assure the safety of all persons, regardless of age and health. The exposure standard for Wireless Party Speaker employs a unit of measurement known as the Specific Absorption Rate, or SAR. The SAR limit set by the FCC is 1.6 W/kg. * Tests for SAR are conducted with the Wireless Party Speaker 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 Wireless Party Speaker while operating can be well below the maximum value. This is because the Wireless Party Speaker 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 Wireless Party Speaker 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 highest SAR value for this Wireless Party Speaker when worn on the body, as described in this user guide, is 0.15 W/Kg (Body-worn measurements differ among Wireless Party Speaker models, depending upon available accessories and FCC requirements). While there may be differences between the SAR levels of various Wireless Party Speaker and at various positions, they all meet the government requirement for safe exposure. The FCC has granted an Equipment Authorization for this Wireless Party Speaker with all reported SAR levels evaluated as in compliance with the FCC RF exposure guidelines. SAR information on this Wireless Party Speaker 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: 2ALNA-BTS56 Additional information on Specific Absorption Rates (SAR) can be found on the Cellular Telecommunications Industry Association (CTIA) web-site at http://www.wow-com.com. * In the United States and Canada, the SAR limit for Wireless Party Speaker 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 SAR test distance is 0mm.
