Authorized Agent: Radiometrics Midwest Corporation (815) 293-0772 – [email protected] RF exposure The following information provides the minimum separation distance for the EUT, as calculated from FCC OET 65 Appendix B, Table 1B “Guidelines for General Population/Uncontrolled Exposure” This calculation is based on the highest EIRP possible from the EUT considering maximum power and antenna gain. The following formulas were used: The peak output power of the EUT is 286 mW (24.6 dBm) and the gain of the antenna is 2 dBi. The EUT is not handheld.
