Range Scale

The range setting controls the size of the area (in nautical miles, kilometers or statute
miles) that appears on your display. The range ring interval is set automatically ac-
cording to the range scale. This automatic selection allows for accurate range mea-
surements on any range setting. The range and range ring interval appear at the top
left-hand corner of the display.
There are three methods to select a range scale:
• RANGE key: Hit RANGE OUT to increase the range,
or RANGE IN to decrease the range.
• Left-click button: Put the cursor on the range indica-
tion. Push the left-click button, and the range box
turns green. Rotate the RotoKey to select a range
then push the key to validate your selection.
• Right-click button: Put the cursor on the range indi-
cation. Push the right-click button to show the Range
pop-up menu, shown below. Rotate the RotoKey to
select a range then push the key to validate your se-
lection.
