How to Edit Own Ship Track
The color and line type of own ship track can be changed. For example, you may want
to change the color and line of the track after returning to port, to distinguish previous
and current track. Four methods of selecting range to edit are available:
• [1. BTWN 2PTS.]: Edits all tracks between two points entered on the plotter display.
Both current track and playback track cannot be edited at the same time.
• [2. SET RNG]: Edits tracks within an area you set.
• [3. WITHIN RNG]: Edits tracks currently shown on the screen.
• [4.OUT OF RNG]: Edits tracks currently not shown on the screen.
Note 1:
The tracks in the internal memory, set to [YES] on [DISPLAY OWN TRACK]
in the [DISPLAY INTERNAL MEMORY] menu, cannot be edited.
Note 2:
If the tracks are being automatically colored according to depth or water tem-
perature, the tracks cannot be edited (see section 3.3.1).
