[. . . ] Wireless Safety March 2007 Whitepaper DECTTM & Bluetooth® Safety Overview DECT and Bluetooth are both short-range radio technology which transmit at a much lower output power than a typical mobile phone. [. . . ] The majority of SAR testing is focused on the head where the current limits for uncontrolled exposure are 2W/kg for 10g Volume Averaged SAR for Europe, Japan and Korea. A SAR value is not usually specified for DECT or Bluetooth headsets as the transmit power is so low as to guarantee a SAR value well below the basic test limits. As such, these headsets meet the exclusion conditions of the European Standards for this type of testing, such as ES 59005 and EN50360/EN50361. Although there is no requirement to do so, Plantronics has commissioned independent testing, with results clearly showing that the SAR levels are far below those required to comply with international standards: · · · SAR for a mobile phone: typically 0. 3 to 1. 5 W/kg for 10g Volume Averaged SAR for a Plantronics CS60 DECT headset: 0. 0006 W/kg for 10g Volume Averaged SAR for a Plantronics M3000 Bluetooth headset ­ 0. 03 W/kg for 10g Volume Averaged The above figures show that a typical Plantronics Bluetooth or DECT headset operates at in the range of just 0. 03% to 1. 5% of the recommended European SAR limit. Considering typical mobiles phones operate in the range between 15% and 75% of the SAR limit, it can clearly be seen that headsets are very low powered. In fact, the SAR values for headsets are so low that accurate measurement is actually quite difficult. Plantronics Bluetooth and DECT headsets comply with relevant global standards. Throughout the European Union, the relevant standard for mobile phones and other devices worn close to the head is EN 50360. An additional factor to consider is that all current specifications require testing to be performed at the maximum power of the device.
