You will notice that as the interval option changes, the setting
values will also alter to reflect the chosen interval. Using the
and
keys highlight the desired time or distance
setting and press the
SELECT
key. The current setting will be
shown at the top of the Sub-Menu.
The Chartnav will record your position every 0.05, 0.1, 0.5 or
1.0 nautical miles or 0.5, 1.0, 2.0 or 5.0 minutes depending
on your selection.
A maximum of 1,000 points can be stored, so choose the
interval based on your needs. If you choose a large track
interval, for example, 1.0 nautical miles, and follow a course
with turns less than a mile apart, you may not have enough
track points, recorded to redraw the track as it was actually
travelled.
When in Charting Mode the number of points remaining,
shown as a percentage of track memory remaining, is
displayed in the Data Display Window on the PLOTTER Page.
When the memory is full the Chartnav will continue to record
new positions but the oldest part of the track will be lost as
new points are added.
When tracking is ON, the vessels track will automatically be
drawn on the chart as the vessel moves. When the screen
redraws the full track will be plotted gradually, as a
background activity, starting at your present position and
working backwards to fill in the entire track.
While sections of the track are being drawn you have full use
of the keyboard and Trackerpad.
To delete the current track memory simply highlight the ERASE
TRACK MEMORY option and press
SELECT
.
When you have finished making the appropriate selections,
press the
PAGE
key to return to the PLOTTER Page.
