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. 4.2 Conducted Power Results Mode GFSK Pi/4DQPSK TX Type SISO SISO Frequency Packet (MHz) 2402 2441 2480 2402 2441 2480 Type DH5 DH5 DH5 2DH5 2DH5 2DH5 Maximum Peak Conducted Output Power (dBm) ANT1 Limit -2.8 <=20.97 -3.67 <=20.97 -4.3 <=20.97 -1.74 <=20.97 -2.72 <=20.97 -3.33 <=20.97 Shenzhen HTT Technology Co.,Ltd.
