Model: NA-P01 Address: #402, 16 Pildong-ro, Jung-gu, Seoul, 04626, Republic of Korea FCC ID: 2BUL4-NA-P01 Per KDB 447498 D01 General RF Exposure Guidance v06 (10/23/2015) section 4.3.1 (a) Standalone SAR test exclusion threshold is applied; a) For 100 MHz to 6 GHz and test separation distances ≤ 50 mm, the 1-g and 10-g SAR test exclusion thresholds are determined by the following: [(max. power of channel, including tune-up tolerance, mW) / (min. test separation distance, mm)] ꞏ [√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  The values 3.0 and 7.5 are referred to as numeric thresholds in step b) below Freq: BLE / 2 440 MHz Tune-up max. power : 0.53 dBm (1.13 mW) Min. Test separation distance : 5 mm SAR exclusion threshold: [1.13/5] x [√2.440] = 0.353 (=0.4, is rouned to one decimal place) * Tune-up tolerance : 0.5 dBm +/- 1.0 dB Therefore, the EUT was not evaluated as the value of SAR exclusion threshold was less than 3 per KDB 447498 D01 v06 section 4.3.1(a)
