Setting Up a Track
You usethe tracksoft keys toswitch thetrack onand to specify theinterval, as
time or distance, at which track points are saved. The time interval between
track points can be set to 1s, 5s, 10s, 30s, 1min, 3min, 5min, 10min or
30minutes. The distance spacing between track points can be set to 0.1nm,
0.5nm or 1.0nm. The interval default is a distance of 0.1nm. The maximum
track length is 750 points. When the track has reached this length, the first
pointsare overwritten.Thetrack issaveduntilyou switch itoff.When the unit
is powered off, the current track (thus far) is retained in memory.
Setting a short time interval between track points is best suited to navigation
within a close or complex environment, e.g. an estuary or marina whereas, in
contrast, a greater distance interval is best suited to a long haul voyage.
Referto thesettingguide showninFigure 5-9to determine the best settingfor
your planned voyage; this is particularly important if you wish to use
SmartRoute to convert your track to a route.

You can change the setting at any time. The setting applies only to the current
track and is not saved as a stored track.
