Record Mode—select Off, Fill, or Wrap.

•Off—does not record a track log.

•Fill—records a track log until the track memory is full.

Where To?

•Wrap—continuously records the track log, replacing the oldest track data with new data.

Record Interval—defines the frequency at which the track plot is recorded. Recording more-frequent plots is more accurate but fills 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-efficient 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.
