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 ε r can be calculated from the below equation (Pournaropoulos and Misra): Table D-1 Composition of the Tissue Equivalent Matter Frequency (MHz) 900 Tissue Head Ingredients (% by weight) Bactericide 0.1 DGBE HEC 1 NaCl 1.45 Sucrose 57 Tween 20 Water 40.45 Table D-2 Recommended Tissue Dielectric Parameters (IEC 62209-1) Page 61 of 80 Report No. OT-202-RWD-032 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 62 of 80 Report No. OT-202-RWD-032 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 63 of 80 Report No. OT-202-RWD-032 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 80 Report No. OT-202-RWD-032 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 80 Report No. OT-202-RWD-032 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 80 Report No. OT-202-RWD-032 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 80 Report No. OT-202-RWD-032 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 80 Report No. OT-202-RWD-032 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 80 Report No. OT-202-RWD-032 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 80 Report No. OT-202-RWD-032 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 71 of 80 Report No. OT-202-RWD-032 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 72 of 80 Report No. OT-202-RWD-032 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 73 of 80 Report No. OT-202-RWD-032 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 74 of 80 Report No. OT-202-RWD-032 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 75 of 80 Report No. OT-202-RWD-032 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 76 of 80 Report No. OT-202-RWD-032 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.
