RF Exposure Calculations: The following information provides the minimum separation distance for each of the antennas provided with the MHX-920 module, 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 system, considering maximum power and antenna gain. The formula used was: S = (Po*G)/(4*pi*r^2) Where S = 0.6 mW/cm^2 for 902.47 MHz Where Po = 100 mW for Yagi antennas (max. power set at factory) Where Po = 1.0 Watt for Omni antennas (max. power user configurable) For: 12 dB Yagi Antenna r = 14 cm 2.5dB Omni Antenna r = 15 cm 6 dB Omni Antenna r = 23 cm The following statement will be presented in the MHX-920 User Manual: WARNING In order to comply with the FCC/IC adopted RF exposure requirements, this transmitter system will be installed by the manufacturer's reseller professional. Installation of all antennas must be performed in a manner that will provide at least 23 cm clearance from the front radiating aperture, to any user or member of the public
