Document DEVICE REPORTGetApplicationAttachment.html?id=3203001FCC: 2AJFZ-MBC005 RF Exposure Report Standard Applicable For The radiation source included into the device the output power is taken from a corresponding RF test report. If needed the output power is converted to source based, time average out power. Finally the output power is compared to FCC and IC low power SAR evaluation exemption level. According to §2.1093 this is a Portable device. FCC SAR test exclusion: According to KDB 447498 D01 General RF Exposure Guidance v06, Appendix A requirement, "The equation and threshold in section 4.3.1 must be applied to determine SAR test exclusion." 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.23 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.24 International Standards Laboratory Report Number: ISL-16LR208FMPE FCC: 2AJFZ-MBC005 1) The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances 50 mm are determined by: [(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,25 where · f(GHz) is the RF channel transmit frequency in GHz · Power and distance are rounded to the nearest mW and mm before calculation26 · 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.
