Remote Contorller Average Factor calculate: The duration of one cycle = 39.20 ms Effective period of the cycle = (0.74 x 12 + 0.26 x 13) ms = 12.26 ms DC = 12.26 ms/39.20 ms = 0.3128 or 31.28 % Therefore, the averaging factor is found by 20log 10 0.3128 = - 10.1 dB

20dB bandwidth = 500kHz 0.25% of the center frequency = 315.07MHz x 0.25% = 787.675kHz > 500kHz

The EUT is powered by 12V DC. During normal use, it sends the message to control the fan and light. The duration of each transmission is less than 1s. Antenna Type: Integral wire antenna. For electronic filing, the brief circuit description is saved in the filename: Technical Description.pdf. 1.2 Related Submittal(s) Grants The receiver option of this transmitter is subject to Certification procedure. 1.3 Test Methodology Radiated emission measurements were performed according to the procedures in ANSI C63.4 (2009). Radiated Emission measurement was performed in a Semi-anechoic chamber. Preliminary scans were performed in the Semi-anechoic chamber only to determine worst case modes. For each scan, the procedure for maximizing emissions in Appendices D and E were followed. All Radiated tests were performed at an antenna to EUT distance of 3 meters, unless stated otherwise in the “Justification Section” of this Application. 1.4 Test Facility The Semi-Anechoic Chamber facility used to collect the radiated data is Intertek Testing Services Shenzhen ltd. Kejiyuan Branch and located at 6F, Block D, Huahan Building, Langshan Road, Nanshan District Shenzhen, P.R.China. This test facility and site measurement data have been fully placed on file with File Number 242492.
