Compliance is demonstrated by showing that the EUT meets the test exemption criteria specified in [3] at a minimum test separation distance of 20 cm. The details of the analysis are presented in Section 4. It should be noted that the test results presented in this test report are valid for the frequency range and for the antenna properties specified in Table 1, in addition to the power level, the power tolerance and TDD downlink duty cycle specified in Table 2. These data, together with information on the physical separation of the antennas were supplied by the client and may affect the validity of the results. The test results were determined for Dot 4455 (equipped with internal antennas) and are also applicable for Dot 4465 connected to external antennas provided that the antenna gain for each branch is equal to or smaller than 4.35 dBi and that the minimum distance between antennas remains equal or larger than 73 mm. Proposed EMF health and safety information for inclusion in the Customer Product Information (CPI) is provided in Appendices A and B. 3 Equipment under test Table 1 summarizes the technical data for the EUT. Photographs and drawing of the EUT are presented in Appendix C. Table 1 Technical data for the EUT.

The minimum test separation distance for which the equipment is shown to comply with the exposure limits must be clearly provided in the operating and installation instructions. A minimum test separation distance of at least 20 cm is required between the device and nearby persons to apply mobile device exposure limits. 4.1 S…
