FCC RF Exposure EUT Description: AKZ-62 Model No.: AKZ-62 FCC ID: 2BDWG-AKZ-62 1. Limits According to KDB 447498 D04 General RF Exposure Guidance v01 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 2. Test Result of RF Exposure Evaluation Output power (dBm) Tune Up Power (dBm) Max Tune Up power dBm/mW Min test separati on distance mm ResultLimit SAR Test Exclusion EDR 1.34 1±1(2) 1.585 5 0.4993.0 Pass Note: PK Output power= conducted power. Conducted power see the test report HK2403191240-E, antenna gain=0dBi Per KDB 447498 D04, when the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion. The test exclusion threshold is 0.499 which is<3.0, SAR 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
