ETLT150527.0028, Page J1 of J2 Head Office: #371-51, Gasan-dong, Geumcheon-gu, Seoul, 153-803, Korea Tel : 82-2-858-0786 Fax : 82-2-858-0788 Open site: #499-1, Sagot-ri, Seosin-myeon, Hwaseong-si, Gyeonggi-do, 445-882, Korea ETLQP-21-F40-0 FCC ID:VH9KDC350A Standard Applicable: According to §1.1307(b)(1), systems operating under the provisions of this section shall be operated in a manner that ensure that the public is not exposed to radio frequency energy level in excess of the Commission’s guideline. This is a Portable device with its physical nature to be used nearby, the distance between radiating structure and human is less than 20 cm. As per KDB 447498 D01, 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 * Bluetooth test mode Measurement Result: This is a portable device and Max peak output power is (2.51 mW) lower than the threshold given and derived as above, where = 2.51 (mW) / 5 (mm) * √2.480 (GHz) = 0.79 < 3.00 * WiFi test mode Measurement Result: This is a portable device and the average output power is (7.08 mW) lower than the threshold given and derived as above, where = 7.08 (mW) / 5 (mm) * √2.472 (GHz) = 2.23 < 3.00 As the result of calculation result indicates, the RF exposure generating from given transmitter (transmitter employed digital modulation) can be excluded from SAR measurement, and is deemed compliant with RF exposure as per FCC.
