According to KDB 447498 D01 General RF Exposure Guidance v05, section 4.3.1 At 100 ㎒ to 6 ㎓ and for test separation distances ≤ 50 mm, the SAR test exclusion threshold is determined according to the following; a) [(max. power of channel, including tune-up tolerance, ㎽) / (min. test separation distance, mm)] x [√f(GHz)] ≤ 3.0 1. SAR test exclusion threshold Frequency : 300.026 ㎒ (min. separation distances = 5 mm) SAR test exclusion thresholds(5 mm) = [(0.00023 / 5) * √0.300026] = 0.0000252 < 3.0. Mode Frequency (MHz) Measured max output Power (mW) Separation Distance (mm) ≤ 3.0 FSK300.0260.0002350.0000252 2. Conclusion : Bluetooth SAR was not required SAR test exclusion
