RayChart 420/420D Chartplotter
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.
