Power listed is conducted. The antenna(s) used for this transmitter must be fixed-mounted on outdoor permanent structures. RF exposure compliance was assessed based on a 0 dBi gain antenna, and the minimum separation distance was determined to be 488.5 cm (16 ft). Higher gain antennas would require greater spacing to ensure compliance RF exposure requirements.

EF: This device may contain functions that are not operational in U.S Territories except as noted in the filing. This grant has extended frequencies as noted in the filing and Section 2.927(b) applies to this authorization.
