These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interferenceto radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: • Reorient or relocate the receiving antenna. • Increase the separation between the equipment and receiver. • Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. • Consult the dealer or an experienced radio/TV technician for help. Radiation Exposure Statement This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator and your body.

Report No.: TBR-C-202310-0239-2 Page: 2 of 3 TB-RF-074-1.0 MPE Calculations for WIFI 1. EUT Operation Condition: Software provided by client enabled the EUT to transmit and receive data at lowest, middle and highest channel individually. 2. 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. R: distance to the center of radiation of the antenna 3. Simultaneous transmission MPE Considerations According to KDB447498: All transmitters and antennas in the host must be either evaluated for MPE compliance, by measurement or computational modeling, or qualify for the standalone MPE test exclusion in section 7.1. Simultaneous transmission MPE test exclusion applies when the sum of the MPE ratios for all simultaneous transmitting antennas incorporated in a host device, based on the calculated/estimated, numerically modeled or measured field strengths or power density, is ≤ 1.0. This means that: ∑ of MPE ratios ≤ 1.0 4. Test Result: Bluetooth worst reported.

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, 2.4G WiFi MPE limit S: 1mW/ cm 2 The MPE is calculated as 0.0217 < 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-----
