FCC RF Exposure FCC ID: SXXKTS-86 Frequency: 2402-2480 MHz (79 channels) Mid-Channel or Highest Peak Power, Conducted: 0.903 dBm Antenna Gain: G = 0 dBi Peak, Radiated = 0.903 dBm + 0 dBi = 0.903 dBm = 1.23 mW SAR Test Exclusion Thresholds specified in KDB447498 Appendix A: Evaluation: The Calculated Radiated Peak output power is taken as worst case, and this emission level appears to be far under the maximum allowed emission level at even the closest distance for 2.4G device specified in this table. Conclusion: The emitted power appears to be (far) below the required limit, so PASS.
