The range setting determines the size of the area (in nautical miles) that will appear on your display. In addition, the range setting will also automatically
adjust the range ring interval so that accurate range measurements may be made while operating on any range setting. The range, range ring interval,
and pulse length appear at the top left-hand corner of the display.
Press the [RANGE (+ or - )] key to change the range scale.
Note
: Range and scale are used interchangeably.
Radar range/plotter display will require constant adjustment due to operational
environment.
