RF EXPOSURE EVALUATION 1. PRODUCT INFORMATION Product Description Vibrating Alarm Clock Model Name YGH314C FCC ID 2AMH2-HM347A 2. EVALUATION METHOD According to 447498 D01 General RF Exposure Guidance v05 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 According to the follow transmitter output power（Pt）formula： Pt=（E x d）2/（30 x gt） Pt=transmitter output power in watts gt=numeric gain of the transmitting antenna (unitess) E=electric field strength in V/m d=measurement distance in meters (m) Pt=-17.98dBm=0.016mW The result for RF exposure evaluation SAR=(0.016mW /5mm) .[√0.43395(GHz)]= 0.067<3.0 for 1-g SAR 4. CONCLUSION The SAR evaluation is not required.
