Product name：Remote Control Production Date：2025Q2 Product Model：RCTGEN2A4AIM Limx Dynamics Technology Co.,Ltd. FCC ID：2BOD5-RCTGEN2A5AIM This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. 68mm 10mm label location

FCC ID: 2BOD5-RCTGEN2A5AIM 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. GFSK: 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 calculation SAR Exclusion threshold SAR test exclusion 2.401 4.31 2.70 5±1 6 3.98 <5 1.23375 3.00 YES 2.441 5.21 3.32 5±1 6 3.98 <5 1.24398 3.00 YES 2.481 8.22 6.64 8±1 9 7.94 <5 2.50232 3.00 YES GFSK Conclusion: For the max result : 0.19873 ≤ 3.0 for 1g SAR, SAR is not required.
