Where To?
Wrap—continuously records the track log, replacing the oldest
track data with new data.
Record Interval
—denes the frequency at which the track plot is
recorded. Recording more-frequent plots is more accurate but lls
the track log faster.
Interval
—sets whether the interval is determined by distance,
time, or resolution. (Select Change to set the value.)
Distance
—records the track based on a distance between points.
Time—records the track based on a time interval.
Resolution—records the track plot based on a variance from
your course. This setting is recommended for the most-efcient
use of memory. The distance value (Change) is the maximum
error allowed from the true course before recording a track point.
Change—sets the value of the interval.
Track Color—sets the color of the track plot.
