                                     FCC RF Exposure
FCC ID: GPO38874
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 v05r01Section 4.3.1 Standalone SAR
test exclusion considerations:͞ hŶůĞƐƐ ƐƉĞĐŝĨŝĐĂůůLJ ƌĞƋƵŝƌĞĚ ďLJ ƚŚĞ ƉƵďůŝƐŚĞĚ Z& ĞdžƉŽƐƵƌĞ 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,

  [(max. power of channel, including tune-up tolerance, mW)/ (min. test separation distance,
mm)] · [Ĝf (GHz)] ζ 3.0 for 1-g SAR andζ 7.5 for 10-g extremity SAR, where:
Ȉf (GHz) is the RF channel transmit frequency in GHz
ȈPower and distance are rounded to the nearest mW and mm before calculation
ȈThe result is rounded to one decimal place for comparison
Ȉ3.0 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 ζ 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.
