General Description of EUT EUT Name : Bluetooth audio adapter Models No. : M9 Pro, M3, M3 Pro, M5, M5 Pro, M6, M8, M9, M10, M10 Pro, M13, M13 Pro, M15, M15 Pro, M16, M16 Pro, M18, M18 Pro, M19, M19 Pro, M20, M20 Pro Model Difference : All PCB boards and circuit diagrams are the same, the only difference is that appearance. Product Description : Operation Frequency: Bluetooth V5.3:2402MHz~2480MHz Number of Channel: 40 channels RF Output Power: GFSK: 2.641dBm π/4-DQPSK: 2.485dBm 8-DPSK: 2.447dBm Antenna Gain: 2dBi External Antenna Power Rating : Input: DC 5V, 1A Li-ion Polymer Battery : DC 3.7V by 1200mAh Rechargeable Li-ion battery Software Version : V2.0 Hardware Version : V1.3 Connecting I/O Port(S) : : Please refer to the User's Manual Remark : The antenna gain provided by the applicant, the verified for the RF conduction test provided by TOBY test lab. Report No.: TBR-C-202305-0170-10 Page: 2 of 3 TB-RF-074-1.0 MPE Calculations for 2.4G 1. Antenna Gain: External Antenna: 2dBi. 2. EUT Operation Condition: Software provided by client enabled the EUT to transmit and receive data at lowest, middle and highest channel individually. 3. Exposure Evaluation: Equation from page 18 of OET Bulletin 65, Edition 97-01 S=(PG)/4πR 2 Where S: power density P: power input to the antenna G: power gain of the antenna in the direction of interest relative to an isotropic radiator.

Report No.: TBR-C-202305-0170-10 Page: 3 of 3 TB-RF-074-1.0 5. Conclusion: As specified in Table 1B of 47 CFR 1.1310- Limits for Maximum Permissible Exposure (MPE), Limits for General Population/ Uncontrolled Exposure Frequency Range (MHz) Power density (mW/ cm 2 ) 300-1,500 F/1500 1,500-100,000 1.0 For Bluetooth:2402~2480 MHz MPE limit S: 1mW/ cm 2 The MPE is calculated as 0.0008 mW / cm 2 < limit 1mW / cm 2 . So, RF exposure limit warning or SAR test are not required. The EUT will only be used with a separation of 20cm or greater between the antenna and nearby persons and can therefore be considered a mobile transmitter per 47 CFR2.1091 (b). The RF Exposure Information page from the manual is included here for reference. Note For a more detailed features description, please refer to the RF Test Report. 6. Conclusion: The measurement results comply with the FCC Limit per 47 CFR 2.1091 for the uncontrolled RF Exposure of mobile device. -----END OF REPORT-----
