I understand the following FCC requirements: 1. Devices subject to the DoC procedure are required to be tested to show compliance with the FCC technical regulations by a recognized accredited testing laboratory. The testing laboratory must be accredited by a Commission approved accreditation body or designated under the terms of a government-to-government Mutual Recognition Agreement (MRA). A listing of those accredited testing laboratories that have been recognized by the Commission is published on the FCC Webpage: https://apps.fcc.gov/oetcf/eas/reports/TestFirmSearch.cfm (Select the "accredited" option to search for FCC recognized accredited test firms.) 2. Test facilities located in countries, where the U.S. does not have an operational Telcom MRA are not recognized by the FCC to test for the DoC procedure. 3. Pt 2.1077 contains the list of information that must be included in the Declaration of Conformity, which must be supplied with each product sold. The DoC compliance info shall be included in the User’s Manual or as a separate sheet.

RF Exposure evaluation According to KDB 447498 D01 General RF Exposure Guidance v05 The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] ·[√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR, where f(GHz) is the RF channel transmit frequency in GHz Power and distance are rounded to the nearest mW and mm before calculation The result is rounded to one decimal place for comparison Worse case is as below: [2412 MHz 9.74dBm(9.42mW) output power] (9.42mW /5mm) ·[√2.412 (GHz)]= 2.96 <3.0 for 1-g SAR Then SAR evaluation is not required
