All deviations in the power measurements from the specific MPR targets shown in the SAR Report are expected and within factory tolerances. 4.LTE Release 14 implementation is limited. The uplink does not support enhanced SC-FDMA. Features such as CoMP, HetNet, Relay, SON, cross carrier scheduling, eICIC, enhanced downlink MIMO, MBMS, M2M/D2 are also not supported. SVLTE is not supported as described in the operational description. 5.This device complies with FCC Part 27.75(a)(1) requirements: Mobile and portable stations that operate on any portion of frequencies in the paired 1755-1780 MHz and 2155-2180 MHz band must be capable of operating on all frequencies in the paired 1710-1780 MHz and 2110-2180 MHz band, using the same air interfaces that the equipment utilizes on any frequencies in the paired 1710-1780 MHz and 2110-2180 MHz band. 6.This device complies with FCC Part 27.77 requirements: Mobile and portable stations in the 1695-1710 MHz and 1755-1780 MHz bands may operate only when under the control of a base station. Base stations that enable mobile or portable equipment to operate in the 1695-1710 MHz and 1755-1780 MHz band are subject to prior coordination requirements. Should you have any questions or comments concerning the above, please contact the undersigned. Sincerely, Confidentail 7.

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. FCC ID: A3LSMG781U Report No: HCT-SR-2008-FC014 F-TP22-03 (Rev.00) 2 / 15 HCT CO.,LTD. 1. Power Reduction Verification for Main Ant This device utilizes a power reduction mechanism for some wireless modes and bands for SAR compliance under hotspot conditions and under some conditions when the device is being used in close proximity to the user’s hand for Main Ant1 The proximity sensor applied to this product has a higher priority than the Hotspot power reduction, so these two conditions do not work simultaneously. and In both cases, powers were reduced to the same Power level. All Hotspot SAR evaluations for this device were performed at the maximum allowed output Power when Hotspot is activated. FCC KDB Publication 616217D04v01r02 section 6 was used as a guideline for selection SAR test distances for this device when being used in phablet use conditions. For detailed measurement conducted power results, please refer to the Section .11 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. 1.1. Power Verification Procedure for Main Ant 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.
