TRACK INTERVAL SETTING

•Manage tracks using the Track List, including Saving, Naming, Eras- ing and Showing a track.

•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 3-41to 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.
