• Convert the current track to a route.
Setting Up a Track
The track soft keys are used to switch the Track on and to specify the
interval at which track points are placed. 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 maximum track length is 750 points per
track. When this limit is reached, track points continue to be placed, but
the oldest points start to be overwritten. Track points continue to be
placed until TRACK OFF is selected. 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, eg. an estuary or
marina whereas, in contrast, a greater distance interval is best suited to a
long haul voyage.
Refer to the setting guide shown in Figure 3-52 to determine the best
setting for 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.
