FCC RF Exposure FCC ID: SNL-16006200 Frequency: 2403.920 - 2472.056 MHz Mid-Channel Peak Power, Conducted, highest valud measured: 18.17 dBm == 65.61 mW Antenna Gain: G = 1.2 dBi Peak, Radiated = 18.17 dBm + 1.2 dBi = 19.37 dBm = 86.5 mW SAR Test Exclusion Thresholds specified in KDB447498 Appendix A: Evaluation: Given the handgrip and position of the swivel antenna, it generally is more than 50mm from the human hand or human body while operating the device. The power this device generates is 86.5 mW, thus below the 96mW that is allowed at 50mm. Conclusion: The emitted power appears to be below the required limit, so PASS.
