[. . . ] S Groups 3 and 4 contains all frequencies within the Indoor Use at Fixed Site band, in 25 kHz increment steps. S The master list (Groups A1­A3) covers all frequencies in 25 kHz increments within the 854­862 MHz band. Shure recommends that you maintain a 500 kHz separation between each receiver in the U4D dual receiver. [. . . ]
