Range modes for different radar systems. Range is in nautical miles (nm).

     System Range = 1    Range = 2   Range = 3    Range = 4

     SPY-1A 50           150         200          250

     SPS-49(V)6          25          50           150  200

     SPS-55 5            15          25           50

These numbers are displayed in the lower right corner of the screen and 
correspond to the radar system's range mode currently selected. Beneath 
the Radar Screen, the display range will be given according to which 
system is activated, and what range mode you have selected. For example, 
if you select the SPY-1A radar system and select Range 3, the display 
range will read "200 nm". This information will be shown above your own 
ship's speed and course.

NOTE:  The display range will be shown only when a radar system is active 
and is displayed.
