A high pass filter is included in the communications input citcuit.The frequency at
which the filter starts to “turn-over” (also known as the knee or -3 dB point for the fil-
ter) is selected by moving a “jumper-link” on the motherboard. The frequencies avail-
able are 60, 160 and 400 Hz.
This switch selects the HPF IN or OUT of circuit.
