Chapter 9 - Creating Tracks
Tracks screen sorted by name
If there aren't any tracks defined yet, as is the case with a new
system or if you've erased all user-defined tracks, the TRACKS
screen will be blank, although the NEW TRACK and START
SAVING keys will be present (the master track is never
displayed on this list). After you've stored one or more
individual tracks, however, the TRACKS screen lists all these
existing tracks, showing whether a track is marked for display
on the CHART screen, and its color, name, start date and time,
and end date and time. If entered, a description of the selected
track appears in the description field near the bottom of the
screen, and details about the extent of the track appear at the
bottom of the screen.
To select a track (indicated by the horizontal stripe), press the
CURSOR PAD up or down.
To the right of the END column is a red vertical slide bar,
which indicates your relative position in the list. The length of
the line relates to the size of the list of tracks. The smaller the
slider, the larger the list; the larger the slider, the smaller the
list.
