Shenzhen Accurate Technology Co., Ltd. Report No.: SZNS220330-11529E-RFA Version 15: 2021-11-09 Page 13 of 75 FCC-BT；RSS-BT FCC §15.247 (i) & §2.1091- MAXIMUM PERMISSIBLE EXPOSURE (MPE) Applicable Standard According to subpart 15.247 (i) and subpart 2.1091 systems operating under the provisions of this section shall be operated in a manner that ensures the public is not exposed to RF energy level in excess of the communication guidelines. Limits for General Population/Uncontrolled Exposure Limits for General Population/Uncontrolled Exposure Frequency Range (MHz) Electric Field Strength (V/m) Magnetic Field Strength (A/m) Power Density (mW/cm 2 ) Averaging Time (Minutes) 0.3-1.34 614 1.63 *(100) 30 1.34-30 824/f 2.19/f *(180/f 2 ) 30 30-300 27.5 0.073 0.2 30 300-1500 / / f/1500 30 1500-100,000 / / 1.0 30 f = frequency in MHz * = Plane-wave equivalent power density Result Calculated Formulary: Predication of MPE limit at a given distance S = 2 4R PG π S = power density (in appropriate units, e.g. mW/cm 2 ) P = power input to the antenna (in appropriate units, e.g., mW). G = power gain of the antenna in the direction of interest relative to an isotropic radiator, the power gain factor, is normally numeric gain. R = distance to the center of radiation of the antenna (appropriate units, e.g., cm) Shenzhen Accurate Technology Co., Ltd.

The tune up conducted power and antenna gain was declared by the applicant. 2. The Bluetooth can transmit at same time with Wi-Fi, the 2.4G Wi-Fi cannot transmit at the same time with the 5G Wi-Fi. Simultaneous transmitting consideration (worst case): The ratio=MPE Wi-Fi /limit+MPE BT /limit=0.063/1+0.002/1=0.065＜1.0, so simultaneous exposure is compliant. To maintain compliance with the FCC’s RF exposure guidelines, place the equipment at least 20cm from nearby persons. Result: Compliant.
