This equipment should be installed and operated with a minimum distance of 70 centimeters (27.5 inches) between the radiator and your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.Wireless 5 GHz Band Statements:As the Access Point can operate in the 5150-5250 MHz frequency band it is limited by the FCC to indoor use only so as to reduce the potential for harmful interference to co-channel Mobile Satellite systems.High power radars are allocated as primary users (meaning they have priority) of the 5250-5350 MHz and 5650-5850 MHz bands. These radars could cause interference and /or damage to the access point when used in Canada.Wireless 4.9 GHz Band Statement:Installation and operartion requires an approved license from the FCC.
