  12. Radio Frequency Exposure
     12.1 Applicable Standards
           The measurements shown in this test report were made in accordance with the procedures given in
           FCC Part 2 (Section 2.1093)
           KDB 447498
           IEEE C95.1:2005

          LIMIT

           KDB 447498 D01 § 4.3(a)
           For 100 MHz to 6 GHz and test separation distances ≤ 50 mm, the 1-g and 10-g SAR test
           exclusion thresholds are determined by the following:
           [(max. power of channel, including tune-up tolerance, mW) / (min. test separation distance,
           mm)] · [√f(GHz)] ≤ 3.0 for 1-g SAR, and ≤ 7.5 for 10-

          *f(GHz) is the RF channel transmit frequency in GHz
          * Power and dis

          *The values 3.0 and 7.5 are referred to as numeric thresholds in step b) below

           The test exclusions are applicable only when the minimum test separation distance is ≤ 50
           mm, and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test
           separation distance is < 5 mm, a distance of 5 mm according to 4.1 f) is applied to determine
           SAR test exclusion

           Remark:
           1. The maximum conducted output power is 4dBm (2.512mW) at 2462MHz (with
              2.8 dBi antenna gain.)
           2. DTS device is not subject to routine RF evaluation; MPE estimate is used to justify the
              compliance.
           3. For mobile or fixed location transmitters, no SAR consideration applied.

          CERPASS TECHNOLOGY CORP.                                               Report No.: TEFI1903241



     12.3 Test Results
           No non-compliance noted.

          According to the KDB447498:
          The SAR test exclusion thresholds Level:
          [(max. power of channel, including tune-up tolerance, mW) /(min. test separation distance,
          mm)] * sqrt (freq. in GHz) < 3


          Calculation
                                    Max.            Max.                       SAR test
                Channel

               Frequency
                                   output          output         (mm)        thresholds
                 (MHz)
                                power(dBm)       power(mW)                       (mW)
               2412-2462            4.00            2.51             5           10.00


           Since the source-based time-averaging conducted output power is well below the SAR
           low threshold level, so the EUT is considered to comply with SAR requirement without
           testing
