C@ EcCIT RF Exposure Evaluation Report Report No.: 118D00140—SARO2 4.2. Standalone SAR Test Exclusion Considerations Standalone 1—g head or body SAR evaluation by measurement or numerical simulation is not required when the corresponding SAR Exclusion Threshold condition, listed below, is satisfied. The 1—g SAR test exclusion threshold for 100 MHz to 6 GHz at test separation distancess 50 mm are determined by: [{max. power of channel, including tune—up tolerance, mW)/{min. test separation distance, mm)] — [Vf(GHz2z)] < 3.0 for 1—g SAR, where ® {(GHz) is the RF channel transmit frequency in GHz ® Power and distance are rounded to the nearest mW and mm before calculation ® The result is rounded to one decimal place for comparison According to the KDB447498 appendix A, the SAR test exclusion threshold for 2450MHz at 5mm test separation distances is 10mW. (max. power o.f channel, |ncI|-1d|ng.tune-up tolerance, mW) *./ Frequency (GHz) <3.0 (min. test separation distance, mm) Based on the above equation, Bluetooth SAR was not required: Evaluation=1.771<3.0 East China Institute of Telecommunications Page Number : 8 of 8 TEL: +86 21 63843300FAX:+86 21 63843301 Report Issued Date _: Oct. 22, 2018
