How to Select Track Plotting Method, Interval

In drawing the track for own ship or other ship, 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 be-
comes full, the oldest track is erased to make room for the latest.

How to select the track plotting method for own ship

The own ship track is traced at an interval of time or distance. The default settings are
10 seconds for track interval 1, 0.1 NM for track interval 2.
Press the PLOT INTVL key consecutively to select the track plotting method. Each
press of the key selects the track interval or stops track plotting as follows:
Track interval 1 → Track interval 2 → Stop of track plotting → Track interval 1 → ...
When selecting [OWN TRACK PLOTTING INTERVAL] in the [DISPLAY SETTING]
menu as the navigation/destination information, the current track interval is displayed
in the NAV information box (see section 1.4.2). Distance is useful for conserving the
track memory, since no track is recorded when the vessel is stationary.
For how to set the track plotting intervals, see section 3.5.2.
