(Shenzhen) Report No.: 2401Z31658E-RFA TR-EM-RF012 Page 94 of 97 Version 4.0 RF EXPOSURE EVALUATION 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. According to KDB 447498 D04 Interim General RF Exposure Guidance v01 MPE-Based Exemption: General frequency and separation-distance dependent MPE-based effective radiated power(ERP) thresholds are in Table B.1 [Table 1 of § 1.1307(b)(3)(i)(C)] to support an exemption from further evaluation from 300 kHz through 100 GHz. is the minimum separation distance in meters f = frequency in MHz Result Mode Frequency (MHz) Tune up conducted power # (dBm) Antenna Gain # ERP Evaluation Distance (m) ERP Limit (W) (dBi) (dBd) (dBm) (W) BLE 2402-2480 4 1.37 -0.78 3.22 0.002 0.2 0.768 2.4G Wi-Fi 2412-2462 16.5 1.37 -0.78 15.72 0.037 0.2 0.768 Note: The tune up conducted power # and antenna gain # were declared and provided by the applicant. BLE and Wi-Fi can’t transmit at the same time To maintain compliance with the FCC’s RF exposure guidelines, place the equipment at least 20cm from nearby persons. Result: Compliant

CIRCUIT DESCRIPTION Overall description of the circuit: * This product uses MCU (RY8310) and WI-FI/BT module TUYA CB3S to control the chromaticity and brightness of a warm light. All operations are finally completed by the TUYA module CB3S link to the network to achieve cloud control function. * Various brightness of the light board can be controlled through the panel buttons and mobile phone APP, mainly used in ambient lights, lighting, creative lights, warning reminders, etc. Control part: This product is realized by the MCU (RY8310) of the machine's LED white light drive and phantom color LED data flow The TUYA module CB3S is responsible for linking to the network in the form of WIFI, and realizes the APP control function issued by the cloud from the mobile phone smart terminal. And through the internal communication interconnection to realize the response call of the mcu native function. CB3S use BK7231NQN32 Chip and 26MHz crystal. Voltage : AC 120V Frequency Range: BLE 1M: 2402-2480MHz 2.4G Wi-Fi: 2412-2462MHz/2422-2452MHz Modulation Technique: BLE: GFSK 2.4G Wi-Fi: DSSS, OFDM
