The tests were performed in order to determine compliance with §1.1307 & §2.1093 rules. Test Facility The test site used by Shenzhen Accurate Technology Co., Ltd. to collect test data is located on the Floor 1, KuMaKe Building, Dongzhou Community, Guangming Street, Guangming District, Shenzhen, Guangdong, China. Accredited by American Association for Laboratory Accreditation (A2LA).The Certificate Number is 4297.01. Shenzhen Accurate Technology Co., Ltd. Report No.: 2504Y23250E-RF Rev:A/4.0(2024/11/01) Page 5 of 6 TR-4-E-R062 RF EXPOSURE Applicable Standard According to FCC §2.1093 and §1.1307(b), systems operating under the provisions of this section shall be operated in a manner that ensure that the public is not exposed to radio frequency energy level in excess of the Commission’s guideline. According to KDB 447498 D04 Interim General RF Exposure Guidance v01, clause 2.1.2 – 1-mW test Exemption: Per § 1.1307(b)(3)(i)(A), a single RF source is exempt RF device (from the requirement to show data demonstrating compliance to RF exposure limits, as previously mentioned) if the available maximum time-averaged power is no more than 1 mW, regardless of separation distance. This exemption applies to all operating configurations and exposure conditions, for the frequency range 100 kHz to 100 GHz, regardless of fixed, mobile, or portable device exposure conditions. This is a standalone exemption, and it cannot be applied in conjunction with any other test exemption. Test Result: For worst case: Mode Frequency Maximum Power 1-mW test Exemption (MHz) (dBm) (mW) SRD 433.92 -34.86 0.0003 Yes Note : E(dBuV/m)=EIRP(dBm)-95.2 for distance 3m Use the highest E-field strength(60.34 dBuV/m) for the evaluation, so the EIRP= 60.34 dBuV/m-95.2=-34.86 dBm Result: Compliance.
