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.
