1. Press the [MENU] key to show the main menu.
2. Press the [4] key to show the MARKS/SHIP’S TRACKS SETUP menu.
3. To set own ship’s track line, select LINE STYLE on PAGE 1/2.
For the sub track or target track lines, select the appropriate item on the PAGE
2/2.
4. Press appropriate numeric key to select the line type desired.
5. Press the [MENU] key several times to close the menu.
3.5 Track Plotting Method, Interval
In drawing the track, the ship’s position is stored into the unit’s memory at an
interval of time or distance. A shorter interval provides better reconstruction of
the track, but the storage time of the track is reduced. When the track memory
becomes full, the oldest track is erased to make room for the latest.
3.5.1 Track plotting method
● Press the [PLOT INTVL] key to select the track plotting method.
Each time the key is pressed the plotting method changes in the sequence
shown below.
Track interval 1→Track interval 2→Hold→Track interval 1 …
The PLOTTER (or PILOT) NAV INFO 1 display shows the current plotting
method.
Distance is useful for conserving track memory, since no track is recorded when
the boat is stationary.
To change the track plotting method (for time and distance) and interval, see the
next paragraph.
