Jeff:
I'm not sure what PNLCS stands for, probably some Yaesu weird acranum. :)
The contour is a signal inhancing filter. So when you togal the DSP button 
to contour, pressing the select button towards the front panel gives you a 
certain audio sound.
When you rotate the select knob counter clockwize and clockwize etc, you 
get different audio sounds that shape the audio. Its mainly used for week 
signal copying but not quite as good as an audio peak filter in CW, which 
the FT-450D does have I think.
So you togal the DSP button through contour, notch which is explanatory, 
DNR which is the noise reduction, width which narrows things from 6KHZ down 
to 3, then 1.8 and in CW from 500HZ down to 250HZ. The last push of the DSP 
button turns it off and allows the select knob to jump up and down in 
frequency or if you set it in the menu, a push of the select knob towards 
the panel, accesses the power adjustment.
This leaves the CS button to activate 1 of many options programmed such as 
moni turn off and on, the digital voice recorder etc but when you enable it 
in the PNLCS menu item, pressing the F key followed by the CS announces 
your configured speech out put. I had mine set to freq and mode 
announcement and gave an S-9 estimate.
