INTERTEK TESTING SERVICE FCC ID: EW780-1960-00D MPE Analysis Report The Equipment-Under-Test (EUT) is a Video Monitor - Baby Unit . I t has a microcontroller and 2.4GHz RF module. The EUT is powered by a 6V DC AC/DC adaptor. For Maximum Permissible Exposure (MPE) evaluation of the unit, the maximum power density at 20 cm from this transmitter shall be less than the General Population / Uncontrolled MPE limit in OET Bulletin 65 and meet the requirement listed in KDB447498 D04 v01. For the 2.4GHz RF portion of the unit, the measured powers among all the measured channels were within its production tolerance. The antenna gain is 0 dBi = 1 (num gain) and its maximum source-based time-averaging duty factor is 100%. From these data and its operating configuration, the exposed power density at a distance (R) of 20 cm from the center of radiation of the antenna can be calculated according to OET Bulletin 65 as follow: T he EIRP radiated power = conducted power (with maximum tolerance) + antenna gain = 17 dBm + 0 dBi = 17 dBm (50.1 mW) The radiated (EIRP) source-based time-averaging output power = (50.1 * 1) mW = 50.1 mW The power density at 20 cm from the antenna = EIRP / 4πR^2 = 0.009967 mW cm-2 I n the frequency range of 1,500 - 100,000MHz, the MPE limit is 1.0 mWcm-2 for general population and uncontrolled exposure. As the measured power density at 20cm from the transmitter is lower than the MPE limit, the compliance to the MPE limit can be ensured by indicating the minimum 20cm separation between the transmitter's radiating structures and body of the user or nearby persons. T he following RF exposure statement is proposed to be included in the user manual: “ FCC RF Radiation Exposure Statement Caution: To maintain compliance with the FCC’s RF exposure guidelines, place the Baby unit at least 20cm from nearby persons.”
