RF EXPOSURE EVALUATION 1. PRODUCT INFORMATION Product Description Puremic Karaoke Mixer Set X2 Test Model X2 FCC ID 2A7ZR-X2 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 BLE: Pt=-3.048dBm=0.50mW The value of the Maximum output power Pt is referred to the test report of the CFR47 §15.247. The result for RF exposure evaluation SAR=(0.50mW /5mm) .[√2.402(GHz)]= 0.16<3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR. BR/EDR: Pt=-2.154dBm=0.61mW The value of the Maximum output power Pt is referred to the test report of the CFR47 §15.247. The result for RF exposure evaluation SAR=(0.61mW /5mm) .[√2.402(GHz)]= 0.19<3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR. 4. CONCLUSION The SAR evaluation is not required.
