Address: Building 6C,Jintong International Industrial Park,Changzhou,Jiangsu,213167 China FCC ID: 2A9IA-ST-16-02 Product: Wireless Remote Control Model No.: ST-16-02 Reference RF report # 6128625069501, 6128625069601 2. 447498 D04 Interim General RF Exposure Guidance v01 B.2 Blanket 1 mW Blanket Exemption The 1 mW Blanket Exemption of § 1.1307(b)(3)(i)(A) applies for single fixed, mobile, and portable RF sources with available maximum time-averaged power of no more than 1 mW, regardless of separation distance. The 1 mW blanket exemption applies at separation distances less than 0.5 cm, including where there is no separation. This exemption shall not be used in conjunction with other exemption criteria other than those for multiple RF sources in paragraph § 1.1307(b)(3)(ii)(A). The 1 mW exemption is independent of service type and covers the full range of 100 kHz to 100 GHz, but it shall not be used in conjunction with other exemption criteria or in devices with higher-power transmitters operating in the same time-averaging period. Exposure from such higher-power transmitters would invalidate the underlying assumption that exposure from the lower-power transmitter is the only contributor to SAR in the relevant volume of tissue. 3. RF Exposure Evaluation Per the test report included herein, for 433.92MHz According to C63.10-2020 Annex G EIRP = pt × gt =( E × d) 2 /30 (G.1) where pt is the transmitter output power in watts gt is the numeric gain of the transmitting antenna (dimensionless) E is the electric field strength in V/m d is the measurement distance in meters (m) ERP = EIRP /1.64 = (E x d) 2 / (30 x 1.64) = (E x d) 2 / 49.2 (G.2) Transmitter output power for 433.92MHz Function Field Strength (EMeas): 92.14(dBuV/m)=0.0405V/m (f=433.92 MHz) Measurement Distance(dMeas): 3 (m) ERP (W): 0.0003W ERP (mW): 0.3mW Report No: 708882511476-00A EMC_SHA_F_R_02.06E TÜV SÜD Certification and Testing (China) Co., Ltd.

Evaluation method Exempt Limit (mW) Verdict ◼ Blanket 1 mW Blanket Exemption 1mW Yes  MPE-based Exemption (ERP) 7mW (ERP) N/A  SAR-based Exemption (Pth) 3060mW N/A Remark: The device does not support simultaneous. So, the device is qualified for SAR test exemption, the exemption report is in lieu of the SAR report. -TÜV SÜD Certification and Testing (China) Co., Ltd.
