Note: More test information about the EUT please refer the RF Test Report. Report No.: TB-MPE171988 Page: 2 of 3 TB-RF-074-1.0 SAR Test Exclusion Calculations 1. FCC: According to KDB 447498 D01 Mobile and Portable Devices RF Exposure Procedures and Equipment Authorization Policies v06. (1) Clause 4.3: General SAR test reduction and exclusion guidance Sub clause 4.31: Standalone SAR test exclusion considerations 1) The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6GHz at test separation distance≤5 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation, mm)]*[√f (GHz) ] ≤3.0 for 1-g SAR [(max. power of channel, including tune-up tolerance, mW)/(min. test separation, mm)]*[√f (GHz) ] ≤7.5.0 for 10-g SAR Report No.: TB-MPE171988 Page: 3 of 3 TB-RF-074-1.0 2. Calculation: Test separation: 5mm Bluetooth Mode (GFSK) Frequency (GHz) Conducted Power (dBm) Turn-up Power Tolerance (dB) Max power of tune up tolerance (dbm) Max power of tune up tolerance (mw) Calculation Value Threshold Value 2.402 -6.596 -6±1 -5 0.316227766 0.0980204 3.0 2.441 -7.277 -7±1 -6 0.251188643 0.0784899 3.0 2.480 -8.195 -8±1 -7 0.199526231 0.0628428 3.0 Bluetooth Mode (π/4-DQPSK) Frequency (GHz) Conducted Power (dBm) Turn-up Power Tolerance (dB) Max power of tune up tolerance (dbm) Max power of tune up tolerance (mw) Calculation Value Threshold Value 2.402 -5.932 -6±1 -5 0.316227766 0.0980204 3.0 2.441 -6.725 -7±1 -6 0.251188643 0.0784899 3.0 2.480 -7.614 -8±1 -7 0.199526231 0.0628428 3.0 Test separation: 5mm The worst RF Exposure Evaluation Worst Calculation Value Total Calculation Value Threshold Value Bluetooth Mode 0.0980204 0.0980204 3.0 So the worst RF Exposure Evaluation is calculated as 0.0980204< limit 3.0.
