Range Scale

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 pulselength appear at the top left-hand corner of the
display.
Press the [RANGE (+ or -)] key to change the range scale.
