The tissue was placed in a nonmetallic container. 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 ’ can be calculated from the below equation (Pournaropoulos and Misra): where Y is the admittance of the probe in contact with the sample, the primed and unprimed coordinates refer to source and observation points, respectively, ,  is the angular frequency, and .

FCC ID: A3LSMX820 SAR EVALUATION REPORT Approved by: Technical Manager DUT Type: Portable Tablet APPENDIX E: Page 1 of 2 A P P E N D I X E : M U L T I-T X A N D A N T E N N A S A R C O N S I D E R A T I O N S E.1 Introduction The following procedures adopted from FCC KDB Publication 447498 D01v06 are applicable to devices with built-in unlicensed transmitters such as 802.11 and Bluetooth devices which may simultaneously transmit with the licensed transmitter. E.2 Simultaneous Transmission Procedures This device contains transmitters that may operate simultaneously. Therefore, simultaneous transmission analysis is required. Per FCC KDB Publication 447498 D01v06 and IEEE 1528-2013 Section 6.3.4.1.2, simultaneous transmission SAR test exclusion may be applied when the sum of the 1g SAR for all the simultaneous transmitting antennas in a specific a physical test configuration is ≤1.6 W/kg. The different test positions in an exposure condition may be considered collectively to determine SAR test exclusion according to the sum of 1g or 10g SAR. E.3 Tablet SAR Analysis Table E-1 Simultaneous Transmission Scenarios of WLAN/BT Notes: 1. For all combinations where the sum of WLAN+BT is less than 1.6 W/kg, there’s no further analysis required for compliance demonstration. 2.

FCC ID A3LSMX820 SAR EVALUATION REPORT Approved by: Technical Manager DUT Type: Portable Computing Device APPENDIX F: Page 1 of 4 APPENDIX F: POWER REDUCTION VERIFICATION Per the May 2017 TCBC Workshop Notes, demonstration of proper functioning of the power reduction mechanisms is required to support the corresponding SAR configurations. The verification process was divided into two parts: (1) evaluation of output power levels for individual or multiple triggering mechanisms and (2) evaluation of the triggering distances for proximity-based sensors. F.1 Power Verification Procedure The power verification was performed according to the following procedure: 1. A base station simulator was used to establish a conducted RF connection and the output power was monitored. The power measurements were confirmed to be within expected tolerances for all states before and after a power reduction mechanism was triggered. 2. Step 1 was repeated for all relevant modes and frequency bands for the mechanism being investigated. 3. Steps 1 and 2 were repeated for all individual power reduction mechanisms and combinations thereof. For the combination cases, one mechanism was switched to a 'triggered' state at a time; powers were confirmed to be within tolerances after each additional mechanism was activated. F.2 Distance Verification Procedure The distance verification procedure was performed according to the following procedure: 1. A base station simulator was used to establish an RF connection and to monitor the power levels. The device being tested was placed below the relevant section of the phantom with the relevant side or edge of the device facing toward the phantom. 2. The device was moved toward and away from the phantom to determine the distance at which the mechanism triggers and the output power is reduced, per KDB Publication 616217 D04v01r02 and FCC Guidance. Each applicable test position was evaluated. The distances were confirmed to be the same or larger (more conservative) than the minimum distances provided by the manufacturer. Triggering states within ±5 mm of the triggering distance, moving towards and away from the phantom, are tabulated below. The influence of table tilt angles to proximity sensor triggering was also evaluated at the smallest sensor triggering distance by rotating the device the edge next to the phantom in 10 degree increments between +- 45 degrees. 3. Steps 1 through 3 were repeated for all distance-based power reduction mechanisms.
