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.
1.Press the [CHART ALIGN] key. M. ALIGNING appears at the top of the screen.
2.Rotate the trackball to shift the chart (or own ship) to the correct position.
3.Press the [CHART ALIGN] key again. MAN ALIGNED appears.
