Center
By pressing the "CENTER" soft key, your current
position will be moved to the center of the track plot
display and the track line dots will be shifted accordingly.
Reset
The "RESET" soft key in the menu restarts your track
plotting by placing your present position in the center of
the track plot screen and erasing all track line dots.
Note: The Twinscope has both a full screen and a split
screen track plotter. Both of these Views are updated
automatically, regardless of what display screen is in use.
Although these two track plot views are similar, the user
may select different ranges for each of these views. For
example, the full screen track plotter can be set up for a
64 mile range, while the split screen track plotter can be
set up for 1/4 mile! This allows you to get two different
instantaneous views of your boat's movement by
selecting the two different track plot views.
