                                        FCC RF Exposure Evaluation

          Exposure category: General population/uncontrolled environment
          EUT Type: Production Unit
          Device Type: Portable Device
          Refer Standard: KDB 447498 D01 General RF Exposure Guidance v06
          FCC Part 2 §2.1093
          Evaluation method
          According to KDB447498 D01 General RF Exposure Guidance v06 Section 4.3.1 Standalone SAR test
          exclusion considerations: “Unless specifically required by the published RF exposure KDB procedures,
          standalone 1-g head or body and 10-g extremity SAR evaluation for general population exposure
          conditions, by measurement or numerical simulation, is not required when the corresponding SAR Test
          Exclusion Threshold condition, listed below, is satisfied. These test exclusion conditions are based on
          source-based time-averaged maximum conducted output power of the RF channel requiring evaluation,
          adjusted for tune-up tolerance, and the minimum test separation distance required for the exposure
          conditions.22 The minimum test separation distance is determined by the smallest distance from the
          antenna and radiating structures or outer surface of the device, according to the host form factor,
          exposure conditions and platform requirements, to any part of the body or extremity of a user or
          bystander (see 5) of section 4.1). To qualify for SAR test exclusion, the test separation distances applied
          must be fully explained and justified by the operating configurations and exposure conditions of the
          transmitter and applicable host platform requirements, typically in the SAR measurement or SAR
          analysis report, according to the required published RF exposure KDB procedures. When no other RF
          exposure testing or reporting is required, a statement of justification and compliance must be included
          in the equipment approval, in lieu of the SAR report, to qualify for the SAR test exclusion. When
          required, the device specific conditions described in the other published RF exposure KDB procedures
          must be satisfied before applying these SAR test exclusion provisions; for example, handheld PTT
          two-way radios, handsets, laptops & tablets etc.23 “
          [(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-g extremity SAR, where:
          • f (GHz) is the RF channel transmit frequency in GHz
          • Power and distance are rounded to the nearest mW and mm before calculation
          • The result is rounded to one decimal place for comparison
          • 3.0 and 7.5 are referred to as the numeric thresholds in the step 2 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 5) in section 4.1 is applied to determine SAR test exclusion.

Remark:
1. Output power including tune up tolerance;
2. When the minimum test separation distance is < 5 mm, a distance of 5 mm according to 5) in
section 4.1 of KDB447498 is applied to determine SAR test exclusion.

            Conclusion
            The measurement results comply with the FCC Limit per 47 CFR 2.1093 for the uncontrolled
            RF Exposure and SAR Exclusion Threshold per KDB 447498 v06.
