RF EXPOSURE EVALUATION 1. PRODUCT INFORMATION Product Description Wireless hands free car kit Model Name BTFM4PD, BTFM4, BTFM4-SP, BTFM4-SP1 FCC ID IKQBTFM4B 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 BT P t = -7.772dBm=0.17mW The value of the Maximum output power P t is referred to the test report of the CFR47 §15.247. The result for RF exposure evaluation SAR=(0.17mW /5mm) .[√2.441(GHz)]= 0.05<3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR. FM Pt=-49.05dBm=0.0000124mW The value of the Maximum output power P t is referred to the test report of the CFR39 §15.239 The result for RF exposure evaluation SAR=(0.0000124mW /5mm) .[√0.0881(GHz)]= 0.000000736<3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR. Simultaneous transmission between Bluetooth and FM transmitter: [(max. power of channel, including tune-up tolerance, mW) / (min. test separation distance, mm)]·[√f(GHz)/x] W/kg, for test separation distances ≤ 50 mm; where x = 7.5 for 1-g SAR and x = 18.75 for 10-g SAR. SAR=(0.05+0.000000736)/7.5=0.007W/kg<1.6W/kg 4. CONCLUSION The SAR evaluation is not required.
