3.5 Hiding the Track
The track lines can be hidden (but recorded). This function is useful when there
are too many tracks to distinguish on the screen and it is hard to distinguish one
from another.
1. Choose TRACK from the PLOTTER menu and then push the [ENTER] knob.
2. Choose VISIBLE and then push the [ENTER] knob.
3. Rotate the [ENTER] knob to select On.
To re-display the track, choose Off.
4. Press the [MENU] key to close the menu.
3.6 Track Plotting Method and Interval
In drawing the own ship track, first the ship’s position fed from the internal GPS
navigator is stored into the unit’s memory at an interval of time or distance. A
shorter interval provides for 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.
3.6.1 Track plotting method
Track may be plotted by time or distance.
1. Choose TRACK from the PLOTTER menu.
