Brand Name : Nightowl Product Description : Operation Frequency: Bluetooth 4.2(BLE): 2402MHz~2480MHz Number of Channel: Bluetooth 4.2(BLE): 40 channels see note(3) RF Output Power: 6.267 dBm (Max) Antenna Gain: 1.0 dBi PCB Antenna Power Rating : Adapter (CS-1202000) Input: 100-240V~, 50/60Hz, 1.5A MAX Output: DC 12V2A Software Version : ---- Hardware Version : ---- Connecting I/O Port(S) : Please refer to the User's Manual Remark : the MPE report used the EUT-2(20210628-28-02). Report No.: TB-MPE182528 Page: 2 of 3 TB-RF-075-1.0 MPE Calculations for Bluetooth 1. Antenna Gain: PCB Antenna: 1.0dBi. 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. R: distance to the center of radiation of the antenna 4.

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 4.2(BLE):2402~2480 MHz MPE limit S: 1mW/ cm 2 The MPE is calculated as 0.0013mW / 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-----
