FCC ID: 2BO3LD1724NAH According to KDB 447498 D04 Interim General RF Exposure Guidance v01. MPE-based Exemption An alternative to the SAR-based exemption is provided in § 1.1307(b)(3)(i)(C), for a much wider frequency range, from 300 ㎑ to 100 ㎓, applicable for separation distances greater or equal to λ/2π, where λ is the free-space operating wavelength in meters. The MPE-based test exemption condition is in terms of ERP, defined as the product of the maximum antenna gain and the delivered maximum time- averaged power. For this case, a RF source is an RF exempt device if its ERP (watts) is no more than a frequency-dependent value, as detailed tabular form in Appendix B. These limits have been derived based on the basic specifications on Maximum Permissible Exposure (MPE) considered for the FCC rules in § 1.1310(e)(1). Table 1 to 1.1307(b)(3)(i)(c) – Single RF Sources Subject to Routine Environmental Evaluation RF Source frequency (㎒) Threshold ERP (watts) 0.3-1.34 1 920 R2 1.34-30 3 450 R 2 /f 2 30-300 3.83 R 2 300-1 500 0.012 8 R 2 f 1 500-100 000 19.2 R 2 2.

Simultaneous Transmission SAR Test Exemption with Respect to Multiple Exemption Criteria Either SAR-based or MPE-based exemption may be considered for test exemption for fixed, mobile, or portable device exposure conditions; therefore, the contributions from each exemption in conjunction with the measured SAR (Evaluated k term) shall be used to determine exemption for simultaneous transmission according to Formula (C.1) [repeated from § 1.1307(b)(3)(ii)(B)]. DTS + Microwave + Bluetooth Low Energy : 0.102 + 0.010 + 0.039 = 0.151 ≤ 1 DTS and Bluetooth Low Energy can’t simultaneous transmission at the same time. Bluetooth Low Energy can’t simultaneous transmission at the same time. 4. Conclusion: No SAR is required.
