Federal Communications Commission Authorization and Evaluation Division Equipment Authorization Branch 7435 Oakland Mills Road Columbia, MD 21046 Applicant’s declaration concerning RF Radiation Exposure We hereby indicate that the product Product description: Wireless Transmitter Model No: TA-58, TA-XXXX (X=0~9,a~z,A~Z or Blank) The equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. The integral antennas used for this transmitter must not be co-located or operating in conjunction with any other antenna or transmitter within the host device. A safety statement concerning minimum separation distances from enclosure of the Product : Transmitter will be integrated in the user’s manual to provide end-users with transmitter operating conditions for satisfying RF exposure compliance. The appropriate information can be drawn from the test report no: W6M22104-20820-C-54 and the accompanying calculations. Company: MIPRO Electronics Co., Ltd. Address: 814, Beigang Rd., Chiayi City 600079, Taiwan Date: 2021-05-21 Registration number: W6M22104-20820-C-54 FCC ID: M5X-TA58 3.6 Automatic Discontinuation of transmission, FCC 15.407 (c) The device shall automatically discontinue transmission in case of either absence of information to transmit or operational failure. This function will be declared by manufacturer. 3.7 Reserved, FCC 15.407 (d) 3.8 Indoor Operation Restriction, FCC 15.407 (e) Within the 5.15–5.25 GHz band, U- NII devices will be restricted to indoor operations to reduce any potential for harmful interference to co-channel MSS operations. This equipment has to be declared by manufacturer of the final product as content of the user manual. 3.9 Equivalent Isotropic Radiated Power (EIRP), FCC 15.407 (f) EIRP = max. conducted output power + antenna gain EIRP = 10.33 dBm + 0 dBi [antenna gain claimed by manufacturer] = 10.33 dBm = 10.7895 mW Test equipment used: ETSTW-RE 055 Worldwide Testing Services(Taiwan) Co., Ltd. Page 23 of 33 Registration number: W6M22104-20820-C-54 FCC ID: M5X-TA58 3.10 Exemption Limits for Routine Evaluation according to 47 CFR FCC Part 2 Subpart J, section 2.1091 FCC OET Bulletin 65 Edition 97.01 determines the equations for predicting RF fields and applicable limits. The prediction for power density in the far-field but will over-predict power density in the near field, where it could be used for walking a “worst case” or conservative prediction. Systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy levels in excess limit for maximum permissible exposure. In accordance with 47 CFR FCC Part 2 Subpart J, section 2.1091 this device has been defined as a mobile device whereby a distance of 20 cm normally can be maintained between the user and the device. E ＝ Electric field (V/m) P ＝ output power (W) G ＝ EUT Antenna numeric gain (numeric) d ＝ Separation distance between radiator and human body (m) The formula can be changed to mW/m 2. Worldwide Testing Services(Taiwan) Co., Ltd. Page 24 of 33 Registration number: W6M22104-20820-C-54 FCC ID: M5X-TA58 Established separation distance is 20 cm. Operating frequency band: 5735-5839 MHz The product meets RF exposure requirement. Because the power density of 0.0021 mW/cm 2 at 5839 MHz is below the power density limit of 1 mW/cm 2 . Limits: Limit for General Population / Uncontrolled Exposure Frequency (MHz) Power Density (mW/cm 2 ) 1500 – 100.000 1.0 Worldwide Testing Services(Taiwan) Co., Ltd. Page 25 of 33

The complexity of the technical specifications, however, means that full and thorough testing is impractical for both technical and economic reasons. Furthermore, there is no guarantee that a test sample which has passed all the relevant tests conforms to a specification. Neither is there any guarantee that such a test sample will interwork with other genuinely open systems. The existence of the tests nevertheless provides the confidence that the test sample possesses the qualities as maintained and that is performance generally conforms to representative cases of communications equipment. The test results of this test report relate exclusively to the item tested as specified in 1.5. The test report may only be reproduced or published in full. Reproduction or publication of …
