The models 512AN_HMW, 512ANX_HMW underwent the certification process with each respective FCC ID number listed in "I. Factory preinstalled Wireless LAN/WiMAX module" on page 2. • Each device is restricted to indoor use due to its operation in the 5.15 to 5.25 GHz frequency range. FCC requires these products to be used indoors for the frequency range 5.15 to 5.25 GHz to reduce the potential for harmful interference to co-channel Mobile Satellite systems. • High power radar are allocated as primary users of the 5.25 to 5.35 GHz and 5.65 to 5.85 GHz bands. These radar stations can cause interference with and/or damage this device. 3
