FCC ID: MZR-YMC624 According to KDB 447498 D04 Interim General RF Exposure Guidance v01 1. SAR-based Exemption A more comprehensive exemption, considering a variable power threshold that depends on both the separation distance and power, is provided in § 1.1307(b)(3)(i)(B). This exemption is applicable to the frequency range between 300 ㎒ and 6 ㎓, with test separation distances between 0.5 ㎝ and 40 ㎝, and for all RF sources in fixed, mobile, and portable device exposure conditions. Accordingly, a RF source is considered an RF exempt device if its available maximum time-averaged (matched conducted) power or its effective radiated power (ERP), whichever is greater, are below a specified threshold. This exemption threshold was derived based on general population 1-g SAR requirements and is detailed in Appendix C. 2. RF Exposure Test Exemptions for Single Source Mode Frequency Range (㎒) Minimum Separation Distance (㎝) Maximum Average Target Power (㏈m) Maximum Tune up (㏈) Maximum Average Output Power Ant.

Conclusion: No SAR is required.
