5.5 Erasing Radar Map Marks and Lines
A total of 3,000 points is allotted for radar map marks and lines. When this
amount is exceeded, no more map marks or lines may be entered unless you
erase unnecessary marks or lines.
5.5.1 Erasing individual radar map marks and lines
1. With the cursor inside the effective display area, roll the wheel to show
“MARK DELETE / EXIT” in the guidance box.
2. Roll the trackball to place the cursor on the radar map mark or line you wish
to erase.
3. Push the left button to erase selected mark or line.
Note: When erasing a line, the cursor location determines how the line will
be erased. To erase a single line segment, place the cursor on the
starting point of the line. When the junction point between two line
segments is erased, the line is redrawn connecting the line segments
which were before and after the erased junction. See the figure below
for an example.
