2.  RADAR, CHART RADAR OPERATION

Note: [SUPPRESS TRAIL AROUND OS] is automatically turned on when [OS TRAIL] 
is activated. The possible ON/OFF combinations between [OS TRAIL] and [SUP-
PRESS TRAIL AROUND OS] are as shown in the table below.

PI lines are useful for keeping a constant distance be-
tween own ship and a coastline or a partner ship when 
navigating. Up to six sets of PI lines are available depend-
ing on the maximum number of PI lines selected on the 
menu.

Control of the orientation and interval of the PI lines is 
done from the PI line box, which is at the bottom-left posi-
tion.

[TRAIL GRAD]: The afterglow of the target trails can be 
shown in a single tone or gradual shading.

[TRAIL COLOR]: The trail color can be selected from the 
colors shown in the left figure. This feature is not available 
with the IMO or A type.
[TRAIL LEVEL]: The level (intensity) of the afterglow that 
extends from radar targets can be adjusted. The higher 
the number the greater the intensity of the afterglow.
[OS TRAIL]: Show or hide trail for own ship.
[SUPPRESS TRAIL AROUND OS]: You can prevent the 
display of sea clutter in true trails about your ship, to clear 
the radar picture.
