Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

FCC ID: RMN-CTSHPIO25 According to KDB 447498 D04 Interim General RF Exposure Guidance v01 1. 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.

Conclusion: No SAR is required.
