FCC ID:A3LSMA426B Report No: HCT-SR-2009-FC001-R1 F-TP22-03 (Rev.00) 1 / 6 HCT CO.,LTD. Appendix H. – Power reduction verification Per the May 2017 TCBC Workshop notes, demonstration of proper functioning of the power reduction mechanism is required to support the corresponding SAR Configurations. The verification process was divided into two parts: 1). Evaluation of output power levels for individual triggering mechanism 2) Evaluation of the triggering distances for proximity-based sensors. 1. Power Reduction Verification The Power verification was performed according to the following procedure: 1. A base station simulator was used to establish a conducted RF connection and output power was monitored. The Power measurements were conformed 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. Step 1 and 2 were repeated for all individual power reduction mechanism and combinations thereof. For the combination cases, one mechanism was switched to a “triggered” state at a time; powers were conformed to be within tolerance after each additional mechanism was activated.

Procedures for determining proximity sensor triggering distances (KDB 616217D04v01r02§6.2) 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 .Each applicable test position was evaluated. The distance were conformed to be the same or larger (more conservative) than the minimum distances provided by the manufacturer. 3. Step 1 and 2 were repeated for the relevant modes, as appropriate 4. Steps1 through 3 were repeated for all distance-based power reduction mechanisms.
