Binary-coded selection (P1016 = 2)
Using this technique up to 16 fixed frequencies can be selected using four control signals.
The fixed frequencies are indirectly selected using the binary coding. The connection
methods to the fixed frequency selector inputs (P1020 ... P1023) are as for the direct
selection mode.
