FCC ID LABEL: Label Location: FCC ID: 2BKRK-L1425-1 Model No.: L1425-1

Shenzhen CTB Testing Co., Ltd. FCC ID:2BKRK-L1425-1 Portable device According to §15.247(e)(i) and §1.1307(b)(1), systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess of the Commission’s guidelines. According to KDB447498 D01 General RF Exposure Guidance V06 The 1-g SAR 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 When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion. 433.9252MHz: Modulation Channel Freq. (GHz) Conduct ed power (dBm) Conducte d power (mW) Tune-up power (dBm) Max tune-up power (dBm) Max tune-up power (mW) Distance (mm) Result calculatio n SAR Exclusion threshold SAR test exclusion ASK 0.43393 -24.4 0.00 -24±1 -23.00 0.01 <5 0.00066 3.00 YES Note:dbm=dbuv/m-95.2-2.15=73.95-95.2-2.15=-23.4dBm(ERP), so the conduct peak power=- 23.4-1=-24.4dBm Conclusion: For the max result : 0.00066≤ FCC Limit 3.0 for 1g SAR.

All measurements were performed radiated and therefore additional antenna gain documentation is not required.
