The following instructions assume that the track functions are displayed.
Setting up a track
Use the track functions 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, 10s, 30s, 1min, 10min or 30 minutes. The distance spacing between track points can be set to 0.05nm, 0.1nm, 0.5nm or 1nm. The maximum track length is 2000 points. When this limit has been reached, track points continue to be placed, but the oldest points start to be deleted. Track ponts continue to be placed until you switch track off; the current track is retained even when the unit is powered off.
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.
When complete, a track can be converted to and saved as a route (SmartRoute).
Refer to the setting guide shown below 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.
