Dip Switch( : 64 frequency option(2401-2464MHz), Frequency interval: 1MHz (As following table).1st to 6th)
Example, As figure 1, the repeater frequency is 2437M, set the 1st, 3rd , 6th dip switch to “1”, the rest to “0”,
the Value summation from 1-6 is 1+4+32=37, so the repeater frequency is 37+2400=2437M.
