Note: More test information about the EUT please refer the RF Test Report. Report No.: TBR-C-202309-0197-11 Page: 2 of 3 TB-RF-074-1.0 The RF Exposure Evaluation for FCC: SAR Test Exclusion Calculations FCC: According to 447498 D04 Interim General RF Exposure Guidance v01. The SAR-based exemption formula of § 1.1307(b)(3)(i)(B), repeated here as Formula (B.2), applies for single fixed, mobile, and portable RF sources with available maximum time-averaged power or effective radiated power (ERP), whichever is greater, of less than or equal to the threshold P th (mW). This method shall only be used at separation distances from 0.5 cm to 40 cm and at frequencies from 0.3 GHz to 6 GHz (inclusive). P th is given by Formula (B.2). and f is in GHz, d is the separation distance (cm), and ERP 20cm is per Formula (B.1). The example values shown in Table B.2 are for illustration only. Table B.2—Example Power Thresholds (mW) Report No.: TBR-C-202309-0197-11 Page: 3 of 3 TB-RF-074-1.0 Calculation: Test separation: 5mm BLE (1Mbps) Frequency (GHz) Conducted Power (dBm) Turn-up Power Tolerance (dB) Max power of tune up tolerance (dBm) Max power of tune up tolerance (mW) Limit P th (mW) 2.402 -4.956 -4±1 -3 0.501 3 2.440 -3.763 -3±1 -2 0.631 3 2.480 -2.960 -2±1 -1 0.794 3 The measurement results comply with the FCC Limit per 47 CFR 2.1093 for the uncontrolled RF Exposure and SAR Exclusion Threshold per KDB 447498 D04, No SAR is required. -----END OF THE REPORT-----
