5.7.2 Chart position correction
There may be a case where the chart overlay is not aligned with the radar image.
This is due to an error in the position fixing system (GPS, Loran, etc.) or the
different coordinates between the position fixing system and the radar. In this
case, align the chart with the radar image as below.
1. With the cursor inside the effective display area, roll the scrollwheel to display
"CHART ALIGN L=OFF / EXIT" in the guidance box.
2. Operate the trackball to align the chart with the radar map. Note that track is
neither recorded nor displayed at this point.
3. Push the left button to set. "CHART ALIGN" appears (in red) at the right side
of the screen.
To release the chart position correction, display "CHART ALIGN L=OFF /
EXIT" in the guidance box then push the left button until "CHART ALIGN"
disappears from the screen.
