With reference to Figure “B”, note the initial position
of the contour when the [CONT] button is pushed. You
may observe the “indentation” in the receiver passband
where the contour filter is placing a low-Q “notch” (per
the setting of Menu item “108 RDSP CNTR LV”, ref-
erenced previous page). Counter-clockwise rotation (to
the left) of the [SELECT](contour) knob causes the
indentation to move towered a lower frequency within
the passband, while clockwise rotation (to the right)
causes the indentation to move toward a higher fre-
quency within the passband. By removing interference
or unwanted frequency components on the incoming
signal, it is possible to make the desired signal rise out
of the background noise/interference, enhancing intel-
ligibility.
