FCC ID: HBWGCU2 UL Project Number: 09NK15074 RF Exposure / SAR statement Applicant: Chamberlain Group Inc. Model: R1000, Wireless Repeater Calculations: The following information provides the minimum separation distance for the highest gain antenna provided with the “R1000” as calculated from FCC OET Bulleting 65 Appendix A, Table (B) Limits for General Population / Uncontrolled Exposure. This calculation is based on the highest EIRP possible from the system, considering maximum power and antenna gain, and considering a f/1500mW/cm 2 (0.601mW/cm 2 ) uncontrolled exposure limit. The Friis formula used was: 2 **4 * r GP S   Where P = 55.5mW (Maximum Peak Output Power) G = 3.27 (Numerical Antenna Gain, 5.14dBi) R = 20.0cm For NTD the S = 0.0361mW/cm 2
