FCC ID: PBN-EK5 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: 923㎒(min. separation distances = 0㎜) Calculation value: 0.052 (㎽) / 5 (㎜) x √ 0.923 = 0.010 So, Calculation value ≤ 3.0 Remark; - Max. Radiated field strength 82.38 (㏈㎶ /m): Max. E.I.R.P. of EUT -12.85㏈m(0.052 ㎽) - 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.
