MARK FEATURE - INSTANT WAYPOINTS
The Mark feature allows 20 waypoints to be entered by
using a single key, the MARK key. This enables pots, drift
nets, and other points of interest along your present course
to be instantly memorised. Pressing the MARK key enters
your present position as a MARK into a reserved area of the
waypoint library. These mark waypoints are automatically
allocated the waypoint library names MARK01 to MARK20
and are waypoint numbers WPT 231 to WPT 250.
To enter a mark simply press the MARK key twice.
The first press will display the waypoint
library, the second and further presses
enter the MARKS. This can be carried
out 20 times.
After all 20 mark library locations have
been used the LCD will show
MARKFULL.
Mark waypoints can be used exactly like any other waypoint
that you have entered using the methods described in the
following pages.
If the Marks are of particular interest then it is good practice
to copy them to other waypoint library locations, name them
for easy identification, and then erase the original MARK. By
erasing the original more MARKs can then be entered,
because once the MARK library locations are full no more
MARKs can be entered. These procedures are explained in
this section of the handbook.
MARKs can be used to define a route. If on a passage you
enter MARKs into the library, and then use them in the
correct order to define a route, they can be used in reverse
to lead the way home. These procedures are explained in
USING ROUTES, later in this handbook.
IMPORTANT NOTE: If MARK waypoints have been used to
create a route ensure that the MARK latitude and longitude
is as you expect. If the MARKs have been erased and then
re-entered (by pressing the MARK key) the MARK latitude
and longitude will have changed and the route could be
entirely different. THIS COULD ENDANGER YOU, YOUR
CREW AND YOUR VESSEL. CHECK BEFORE YOU
ENGAGE THE ROUTE.
It is suggested that you use a table to record your MARK
waypoints, it will help you identify and record them in the
future. The following pages could be copied for this purpose
or a table of your own design could be used.
