Maximum Permissible Exposure 12.1 Applicable Standard 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 levels in excess limit for maximum permissible exposure. In accordance with 47 CFR FCC Part 2 Subpart J, section 2.1091 this device has been defined as a mobile device whereby a distance of 0.9 m normally can be maintained between the user and the device. 12.2 MPE Calculation Method E ＝ Electric field (V/m) P ＝ output power (W) G ＝ EUT Antenna numeric gain (numeric) d ＝ Separation distance between radiator and human body (m) The formula can be changed to Worldwide Testing Services (Taiwan) Co., Ltd. Page 85 of 87 Registration number: W6M22003-19794-C-1 FCC ID: L9N-7085PUE5 EIRP = max. conducted output power + antenna gain+ tune up EIRP = 38.75 dBm + (3 dBi [antenna gain claimed by manufacturer]+ 0.35 dB [tune up]) = 42.1 dBm = 16218.101 mW Established separation distance is 35 cm. Operating frequency band: 406~430 MHz, 440~470 MHz The product meets RF exposure requirement. Because the power density of 1.0535 mW/cm 2 at 430 MHz is below the power density limit of 1.4333 mW/cm 2 . Worldwide Testing Services (Taiwan) Co., Ltd. Page 86 of 87
