FCC ID: A5MBT500A According to KDB 447498 D01 General RF Exposure Guidance v06, section 4.3.1 At 100 MHz to 6 GHz and for test separation distances ≤ 50mm, 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: 2 480 MHz (min. separation distances = 5 mm) SAR test exclusion thresholds (5 ㎜) = 3 x 5 / (√ 2.480 ) = 9.525 ㎽ Test mode Max. Tune-up Tolerance (mW) SAR Test Exclusion Thresholds (5mm) (mW) Classic BT 4.0 9.525 Calculation value: 4.00 (㎽) / 5 (㎜) x √ 2.480 = 1.260 So, Calculation value ≤ 3.0 Remark: -For Classic BT Max. conducted power is 3.02 (㎽), so 4.00 (㎽) was calculated. -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.
