FCC ID: 2AEQT-KMDC66CH0 According to KDB 447498 D01 General RF Exposure Guidance v06, section 4.3.1 SAR Test Exclusion Threshold for < 100 MHz and < 200 mm as per Appendix C SAR exclusion for 100 MHz at 50 mm is 237 mW. For frequencies below 100 MHz, the following may be considered for SAR test exclusion (also illustrated in Appendix C):33 1) For test separation distances > 50 mm and < 200 mm, the power threshold at the corresponding test separation distance at 100 MHz in step b) is multiplied by [1 + log(100/f(MHz))] 237 * [1 + log(100/f(13.56))]=422 mW 2) For test separation distances ≤ 50 mm, the power threshold determined by the equation in c) 1) for 50 mm and 100 MHz is multiplied by ½ 422 *(1/2)= 221mW 1. SAR test exclusion threshold Frequency: 13.56 MHz, test separation distances ≤ 50 mm. Max. Tune-up Tolerance (mW) SAR Test Exclusion Thresholds (mW) 0.00018 221 Remark: -Based on field strength 57.55 dBuV/m at 3m transmit power(eirp) of the device was calculated as 0.00018 mW using free space formula. 2. Conclusion: No SAR is required.
