Lots of settings, all done by selecting the setting with short push or 
long push of the right-hand buttons and setting values with the knob. 
For day-to-day operation, I have the display scaling set for 24 dB full 
screen and set the bottom of the display so that there's a small bit of 
"grass" visible. It is also a VERY good idea to set display averaging to 
a pretty long value (top button). I use the maximum setting. What this 
does is cause random noise to average to zero (because it's random) and 
add the signals (because they are the same on every sweep).

For contests or DX pileups, when there are many strong signals, I adjust 
the display scaling as high as 42 dB (but never higher).
