Front-Panel Operations
One-Line Diagrams
As Figure 4.40 and Figure 4.41 show, panning is discontinuous and necessitates
your toggling between two front-panel screens.
➤ Screen 1 plus the common area (Figure 4.40)
➤ Screen 2 plus the common area (Figure 4.41)
When you specify a custom screen, be sure to separately specify these three
