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 20cm normally can be maintained between the user and the device. RF Exposure Evaluation Result RF exposure evaluation method is based on KDB 447498 D01, this calculation is based on the conducted power, maximum power and antenna gain with provides the minimum separation distance. The formula shown below is from OET Bulletin 65 Edition 97-01 Per KDB 447498 D01: S = PG/(4πR 2 ) S = Power Density (mW/m 2 ) P = RF output Power (mW) G = EUT Antenna gain (numeric) R = Separation distance between radiator and human body (cm) From the minimum separation distance, R=20cm Test mode Max.
