2.18 Remove the heading line/navigation data
This function is used when a target is overlapped with a heading line and hard to be distinguished.
1
Press OFF key to temporarily hide the heading line.
For safety reason, the heading line disappears only while the key is pressed. (It is not possible to
keep it removed.)
Continue pressing OFF key for 2sec. All navigation tool data (RR, EBL, VRM, ERBL, PI, [MAP],
such as COAST LINE, NAV LINE, ROUTE, EVENT MKR, and AREA, etc.) will hide.
2.19 Target trail
Other ships trails are displayed by following procedures.
Two display modes, relative display REL and true display TRUE are available.
At the start of trail
, “TRAIL” characters at lower left of the display change to yellow. When trail time has
passed, character color turns white.
Note:
• The trail by its nature records and displays past images. The trail does not display right after
transmission is started.
In addition, after the change of [TIME], or after the change of two or more steps in [RANGE], the trail
will disappear, because the recording is reset (erased).
• The trail [TIME] and [REL] or [TRUE] mode can be changed directly at the lower left of the display,
with trackball and ENT key, without using menu function.
1
Press MENU key to display
“Menu”.
Select [TRAIL] => [TRUE / REL], and press ENT after making selection.

There are additional set up items, [TIME], [SHAPE], [TRAIL LEVEL], [CLEAR], [RANGE KEEP],
