INTERTEK TESTING SERVICES RF Exposure The Equipment Under Test (EUT) is a WiFi PIR Dimmer Switch with Wi-Fi function operating at 2412-2462MHz for 802.11b/g/n-HT20, 11 channels with 5MHz channel spacing. The EUT is powered by AC120V/60Hz. For more detailed features description, please refer to the user’s manual. 2.4GHz Wi-Fi: Antenna Type: Integral Antenna. Antenna Gain: 1.5dBi. Modulation Type: CCK, BPSK, QPSK, 16QAM, 64QAM, DQPSK, DBPSK. The nominal conducted output power specified: 20dBm (Tolerance: +/-3dB). The maximun conducted output power for the EUT is 22.52dBm in the frequency 2412MHz(IEEE 802.11b) which is within the production variation. The minimum conducted output power for the EUT is 21.87dBm in the frequency 2462MHz(IEEE 802.11n-HT20) which is within the production variation. According to FCC Part 2.1091, this unlicensed transmitting devices is categorically excluded from routine environmental evaluation for RF exposure prior to equipment authorization or use, According to the KDB 447498 and OET 65, the simple calculation as below: The source-based time averaged maximum radiated power = 20dBm+3dB+1.5dBi = 24.5dBm = 281.8mW From above data, the exposed power density at a distance (R) of 20cm from the center of radiation of the antenna for 2.4GHz WIFI band can be calculated according to OET 65 as follow: = 281.8mW/ 4 πR^2 = 0.056mW/cm^2 <1mW/cm^2 The MPE limit is 1.0 mW/cm^2 for general population and uncontrolled exposure in the Wi-Fi frequency range according to FCC Part 1.1310. 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 structure and body of the user or nearby persons. The following RF exposure statement or similar sentence is proposed to be included in the user manual: “FCC RF Radiation Exposure Statement Caution: This Transmitter must be installed to provide a separation distance of at least 20 cm from all persons.” FCC ID: 2ASVU-U371
