FCC RF Exposure

Product Name: RecNow AI Recorder FCC ID: 2BOOV-WT-R21 Model(s): WT-R21

1. Limits According to KDB 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: Result=P/D*F F= the RF channel transmit frequency in GHz P=Maximum turn-up power in mw D=Min. test separation distance in mm

Per KDB 447498 D01, when the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine RF Exposure test exclusion. The test exclusion threshold is 0.198 which is<= 3, RF Exposure testing is not required.

Note: Exclusion Thresholds Results=[(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] ·[f(GHz)]
f(GHz) is the RF channel transmit frequency in GHz Distance=5mm
