2.6.4 Track plotting method and interval for own ship track
In drawing the own ship track, first the ship’s position fed from position-fixing
equipment 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.
Track plotting method
Track may be plotted by time or distance. The default setting is “time.”
1. Press the [MENU] key followed by the CHART SETUP and TRACKS &
MARKS CONTROL soft keys to open the TRACK CONTROL menu.
