FCC ID: RVBXPM170YN According to KDB 447498 D01 General RF Exposure Guidance v06. At 100 ㎒ to 6 ㎓ and for test separation distances ≤ 50 ㎜, the SAR test exclusion threshold is determined according to the following [(max. power of channel, including tune-up tolerance, ㎽) / (min. test separation distance, ㎜)] x [√f(㎓)] ≤ 3.0 1. SAR test exclusion threshold Frequency: 2 460 ㎒ (min. separation distances = 0 ㎜) SAR test exclusion thresholds(5 ㎜) = 3 x 5 / (√ 2.460 ) = 9.564 ㎽ Calculation value: 0.281 (㎽) / 5 (㎜) x √ 2.460 = 0.088 So, Calculation value ≤ 3.0 Remark; - Max. Radiated field strength 89.72 (㏈㎶/m): Max. E.I.R.P. of EUT -5.51 ㏈m (0.281 ㎽) - When the minimum test separation distance is < 5 ㎜, a distance of 5 ㎜ is applied to determine SAR test exclusion. 2. Conclusion: No SAR is required.
