                                                       FCC RF Exposure
         Exposure category: General population/uncontrolled environment
         EUT Type: Production Unit
         Device Type: Portable Device
         Refer Standard: KDB 447498 D01 General RF Exposure Guidance v05r02
         FCC Part 2 §2.1093
         Evaluation method
         According to KDB447498 D01 General RF Exposure Guidance v05r02 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 separa on 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.
