Shenzhen Accurate Technology Co., Ltd. Report No.: RA221125-56834E-RF-00 Version 11: 2021-11-09 Page 11 of 61 FCC-BT FCC§15.247 (i), §1.1307 (b) (3) &§2.1093 – RF EXPOSURE Applicable Standard According to FCC §2.1093 and §1.1307(b) (3), 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 SAR-Based Exemption: SAR-based thresholds are derived based on frequency, power, and separation distance of the RF source. The formula defines the thresholds in general for either available maximum timeaveraged power or maximum time-averaged ERP, whichever is greater. Per § 1.1307(b)(3)(i)(B), for single RF sources (i.e., any single fixed RF source, mobile device, or portable device, as defined in paragraph (b)(2) of this section): A single RF source is exempt if: the available maximum time-averaged power or effective radiated power (ERP), whichever is greater, is less than or equal to the threshold P th (mW) described in the following formula. This method shall only be used at separation distances (cm) from 0.5 centimeters to 40 centimeters and at frequencies from 0.3 GHz to 6 GHz (inclusive). P th is given by: Shenzhen Accurate Technology Co., Ltd. Report No.: RA221125-56834E-RF-00 Version 11: 2021-11-09 Page 12 of 61 FCC-BT For worst case: Exemption limit: For f=2.48 GHz, d =0.5 cm, the P th =2.72 mW The higher of the available maximum time-averaged power or effective radiated power (ERP): The antenna gain is 0 dBi (-2.15 dBd), 0 dBd=2.15 dBi The maximum tune-up conducted power is 1.5 dBm (1.41 m W), which less than 2 .72mW@2480 MHz exem ption limit. So the stand-alone SAR evaluation can be exempted.
