Setting Up a Track
Setting Up a Track
You use the track soft keys to switch the track on and to specify the interval, 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
points are overwritten. The track is saved until you switch it off. 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.
Refer to the setting guide shown in Figure 5-9 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.
Figure 5-9: Track Interval Setting Guide
You can change the setting at any time. The setting applies only to the current
track and is not saved as a stored track.
➤ To set up a track:
1. Press the
MORE soft key to access the TRACK INTERVAL soft keys.
Press the appropriate soft key to set either a time interval or a distance inter-
val; press the
UP arrow to increase the interval, the DOWN arrow to decrease
the interval.
