Sample ID : HC-C-202407-0003-02-01 Product Description : Operation Frequency: 433.925MHz Antenna Gain: -5.1dBi PCB Antenna Power Rating : 3V DC (powered by 2pcs AAA batteries) Software Version : HXD2151V04 DT202406191603 CK55EC.ZCW Hardware Version : HXD2151 V2 Remark: The antenna gain provided by the applicant, and verified for the RF conduction test and adapter provided by TOBY test lab. Note: More test information about the EUT please refer the RF Test Report. Report No.: TBR-C-202407-0003-1 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-202407-0003-1 Page: 3 of 3 TB-RF-074-1.0 Calculation: Frequency (MHz) Max. Output Power (dBuV/m) Max. Output Power (dBm) Tolerance ± (dB) Output power (Max. Turn-up Procedure) (mW) Limit P th (mW) 433.925MHz 66.16 -35.1 ±1 0.000389 22 Note: For conducted measurements below 1000 MHz, the field strength shall be computed as specified in item d), and then an additional 4.7 dB shall be added as an upper bound on the field strength that would be observed on a test range with a ground plane for frequencies between 30 MHz and 1000 MHz, or an additional 6 dB shall be added for frequencies below 30 MHz. So: EIRP=E+20log3-104.8-(4.7 or 6) Note: At separation distance of ≤5 mm 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-----
