Trapped air bubbles beneath the flange were minimized by placing the probe at a slight angle. 3) The complex admittance with respect to the probe aperture was measured. 4) The complex relative permittivity İ r can be calculated from the below equation (Pournaropoulos and Misra): Table D-1 Composition of the Tissue Equivalent Matter Frequency (MHz) 2 450 Tissue Head Ingredients (% by weight) Bactericide - DGBE - HEC - NaCl 0.1 Sucrose - Tween 20 45.0 Water 54.9 Table D-2 Recommended Tissue Dielectric Parameters (IEC 62209-1) Page 55 of 74 Report No. OT-20O-RWD-045 EMC-003 (Rev.2) ONETECH Corp.: 43-14, Jinsaegol-gil, Chowol-eup, Gwangju-si, Gyeonggi-do, 12735, Korea (TEL: 82-31-799-9500, FAX: 82-31-799-9599) Figure D-1 Liquid Height for Head & Body Position (SAM Twin Phantom) Figure D-2 Liquid Height for Body Position (ELI Phantom) Page 56 of 74 Report No. OT-20O-RWD-045 EMC-003 (Rev.2) ONETECH Corp.: 43-14, Jinsaegol-gil, Chowol-eup, Gwangju-si, Gyeonggi-do, 12735, Korea (TEL: 82-31-799-9500, FAX: 82-31-799-9599) Appendix D.1 DAK3.5 Dielectric Probe Calibration Page 57 of 74 Report No. OT-20O-RWD-045 EMC-003 (Rev.2) ONETECH Corp.: 43-14, Jinsaegol-gil, Chowol-eup, Gwangju-si, Gyeonggi-do, 12735, Korea (TEL: 82-31-799-9500, FAX: 82-31-799-9599) Page 58 of 74 Report No. OT-20O-RWD-045 EMC-003 (Rev.2) ONETECH Corp.: 43-14, Jinsaegol-gil, Chowol-eup, Gwangju-si, Gyeonggi-do, 12735, Korea (TEL: 82-31-799-9500, FAX: 82-31-799-9599) Page 59 of 74 Report No. OT-20O-RWD-045 EMC-003 (Rev.2) ONETECH Corp.: 43-14, Jinsaegol-gil, Chowol-eup, Gwangju-si, Gyeonggi-do, 12735, Korea (TEL: 82-31-799-9500, FAX: 82-31-799-9599) Page 60 of 74 Report No. OT-20O-RWD-045 EMC-003 (Rev.2) ONETECH Corp.: 43-14, Jinsaegol-gil, Chowol-eup, Gwangju-si, Gyeonggi-do, 12735, Korea (TEL: 82-31-799-9500, FAX: 82-31-799-9599) Page 61 of 74 Report No. OT-20O-RWD-045 EMC-003 (Rev.2) ONETECH Corp.: 43-14, Jinsaegol-gil, Chowol-eup, Gwangju-si, Gyeonggi-do, 12735, Korea (TEL: 82-31-799-9500, FAX: 82-31-799-9599) Page 62 of 74 Report No. OT-20O-RWD-045 EMC-003 (Rev.2) ONETECH Corp.: 43-14, Jinsaegol-gil, Chowol-eup, Gwangju-si, Gyeonggi-do, 12735, Korea (TEL: 82-31-799-9500, FAX: 82-31-799-9599) Page 63 of 74 Report No. OT-20O-RWD-045 EMC-003 (Rev.2) ONETECH Corp.: 43-14, Jinsaegol-gil, Chowol-eup, Gwangju-si, Gyeonggi-do, 12735, Korea (TEL: 82-31-799-9500, FAX: 82-31-799-9599) Page 64 of 74 Report No. OT-20O-RWD-045 EMC-003 (Rev.2) ONETECH Corp.: 43-14, Jinsaegol-gil, Chowol-eup, Gwangju-si, Gyeonggi-do, 12735, Korea (TEL: 82-31-799-9500, FAX: 82-31-799-9599) Page 65 of 74 Report No. OT-20O-RWD-045 EMC-003 (Rev.2) ONETECH Corp.: 43-14, Jinsaegol-gil, Chowol-eup, Gwangju-si, Gyeonggi-do, 12735, Korea (TEL: 82-31-799-9500, FAX: 82-31-799-9599) Page 66 of 74 Report No. OT-20O-RWD-045 EMC-003 (Rev.2) ONETECH Corp.: 43-14, Jinsaegol-gil, Chowol-eup, Gwangju-si, Gyeonggi-do, 12735, Korea (TEL: 82-31-799-9500, FAX: 82-31-799-9599) Page 67 of 74 Report No. OT-20O-RWD-045 EMC-003 (Rev.2) ONETECH Corp.: 43-14, Jinsaegol-gil, Chowol-eup, Gwangju-si, Gyeonggi-do, 12735, Korea (TEL: 82-31-799-9500, FAX: 82-31-799-9599) Page 68 of 74 Report No. OT-20O-RWD-045 EMC-003 (Rev.2) ONETECH Corp.: 43-14, Jinsaegol-gil, Chowol-eup, Gwangju-si, Gyeonggi-do, 12735, Korea (TEL: 82-31-799-9500, FAX: 82-31-799-9599) Page 69 of 74 Report No. OT-20O-RWD-045 EMC-003 (Rev.2) ONETECH Corp.: 43-14, Jinsaegol-gil, Chowol-eup, Gwangju-si, Gyeonggi-do, 12735, Korea (TEL: 82-31-799-9500, FAX: 82-31-799-9599) Page 70 of 74 Report No. OT-20O-RWD-045 EMC-003 (Rev.2) ONETECH Corp.: 43-14, Jinsaegol-gil, Chowol-eup, Gwangju-si, Gyeonggi-do, 12735, Korea (TEL: 82-31-799-9500, FAX: 82-31-799-9599) APPENDIX E: SAR SYSTEM VALIDATION Per FCC KDB Publication 865664 D02v01r02, SAR system validation status should be documented to confirm measurement accuracy. The SAR systems (including SAR probes, system components and software versions) used for this device were validated against its performance specifications prior to the SAR measurements. Reference dipoles were used with the required tissue-equivalent media for system validation, according to the procedures outlined in FCC KDB Publication 865664 D01v01r04 and IEEE 1528-2013. Since SAR probe calibrations are frequency dependent, each probe calibration point was validated at a frequency within the valid frequency range of the probe calibration point, using the system that normally operates with the probe for routine SAR measurements and according to the required tissue-equivalent media. A tabulated summary of the system validation status including the validation date(s), measurement frequencies, SAR probes and tissue dielectric parameters has been included.
