RF EXPOSURE EVALUATION 1. PRODUCT INFORMATION Product Description SLING AND SING KARAOKE Model Name CR-2713A FCC ID 2AE67-CR2713A 2. EVALUATION METHOD According to 447498 D01 General RF Exposure Guidance v06 The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] ·[√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR. Where f(GHz) is the RF channel transmit frequency in GHz Power and distance are rounded to the nearest mW and mm before calculation 3. CALCULATION Wireless microphones: Pt=8.521dBm=7.099mW The result for RF exposure evaluation SAR=(7.099mW /5mm) .[√0.590(GHz)]= 1.090<3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR. 4. CONCLUSION The SAR evaluation is not required.
