Report NO.: ZKT-260821L1388E-2 Page 7 of 8 According to KDB 447498 D01 General RF Exposure Guidance v06 and part 2.1093, Unless specifically required by the published RF exposure KDB procedures, standalone 1-g head or body and 10-g extremity SAR evaluation for general population exposure conditions, by measurement or numerical simulation, is not required when the corresponding SAR Test Exclusion Threshold condition(s), listed below, is (are) satisfied. For 100 MHz to 6 GHz and test separation distances ≤ 50 mm, the 1-g and 10-g SAR test exclusion thresholds are determined by the following: [(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 The result is rounded to one decimal place for comparison Report NO.: ZKT-260821L1388E-2 Page 8 of 8 Here, For SRD Antenna Type Frequency Power (dBuV/m) @3m Power (dBm) Turn up Power (MHz) Dipole Antenna 434.6025 71.86 -23.34 -24±1dBm FPC Antenna 433.8025 71.15 -24.05 -24±1dBm Horn Antenna 433.8025 71.53 -23.67 -24±1dBm Sucker antenna 433.8025 71.14 -24.06 -24±1dBm Note: Power(dBm) = dBuV/m@3m -95.2 Antenna Type Frequency (MHz) Separation distance (cm) Tune Up Power (dBm) Max Tune Up Power (mW) Power Density (mW/cm²) Limit (mW/cm²) Result Dipole Antenna 434.6025 20 -23 0.005010.000001 0.2897 Pass FPC Antenna 433.8025 20 -23 0.00463 0.000001 0.2897 Pass Horn Antenna 433.8025 20 -23 0.00463 0.000001 0.2897 Pass Sucker antenna 433.8025 20 -23 0.00463 0.000001 0.2897 Pass Conclusion: Note: 1.The Maxinum power is less than the limit, complies with the exemption requirements.
