2.6. A-Scope Diameters
The FCV-600 and FCV-800 show the A-Scope with the coverage in diameters at the bottom and middle layers.
Previously, only the radius (half the total distance) was shown. The indication of diameter helps to intuitively identify
how wide the total transmission area is covered at each layer.
