Chart position correction
There may be a case where the radar picture does not match the chart overlay.
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. Note that track is neither
recorded nor plotted while chart position is being corrected.

screen.
2. Rotate the trackball to shift the chart (or own ship) to the correct position.
