For use in America and this chip will not support/enable BDR (GFSK), EDR (π/4-DQPSK, 8DPSK) and BLE 2M. The BDR (GFSK), EDR (π/4-DQPSK, 8DPSK) and BLE 2M function has been shielded by the manufacturer using the software. The RF Chip, model: RTL8720CF installed in our product Govee Smart Air Quality Monitor, Model: H5106, FCC ID: 2A7VD-H5106, supports 2.4G Wi-Fi(802.11b/g/n20/n40 mode) and BT/BLE, but for marketing purpose, this chip only supports 2.4G Wi-Fi(802.11b/g/n20 mode). The 2.4G Wi-Fi(802.11n40 mode) and BT/BLE were disabled to use by manufacture in the software, the end user has no capability to activate it.

Shenzhen Accurate Technology Co., Ltd. Report No.: SZNS220818-37699E-RF-00 Version 12: 2021-11-09 Page 12 of 58 FCC- BLE&2.4G Wi-Fi FCC §15.247 (i) & §1.1307 (b) (3) & §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. According to KDB 447498 D04 Interim General RF Exposure Guidance 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)(1)(i)(C)] to support an exemptionfrom further evaluation from 300 kHz through 100 GHz. Ris the minimum separation distance in meters f = frequency in MHz For multiple RF sources: Multiple RF sources are exempt if: in the case of fixed RF sources operating in the same time-averaging period, or of multiple mobile or portable RF sources within a device operating in the same time averaging period, if the sum of the fractional contributions to the applicable thresholds is less than or equal to 1 as indicated in the following equation: Shenzhen Accurate Technology Co., Ltd. Report No.: SZNS220818-37699E-RF-00 Version 12: 2021-11-09 Page 13 of 58 FCC- BLE&2.4G Wi-Fi Result Mode Frequency (MHz) Tune up conducted power Antenna Gain ERP Evaluation Distance (m) ERP Limit (W) (dBm) (dBi)(dBd)(dBm)(W) BLE 2402-2480 3.0 2.73 0.58 3.58 0.002 0.2 0.768 Wi-Fi 2412-2462 14.5 1.78 -0.37 14.13 0.026 0.2 0.768 Note: 1. The tune up conducted power and antenna gain was declared by the applicant. 2. The BLE can transmit at the same time with the Wi-Fi. 3. 0dBd=2.15dBi Simultaneous transmitting consideration (worst case): The ratio=ERP BLE /limit+ERP Wi-Fi /limit=0.002/0.768+0.026/0.768=0.036＜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.
