Parallel Index (PI) Lines

The parallel index lines are useful for keeping a constant distance between own ship
and a coastline or a partner ship when navigating. There are six sets of PI lines (PI-
P6) on the [PI] page and you can turn them on or off individually. Select the PI line to
process with the [Display] pull-down list then click the [ON] or [OFF] button as appro-

PI line.
The bearing can be set two ways: with the scrollwheel or dragging the PI line on the
screen.
