Figure 3 shows the same chart, but with the chart's viewing
angle now set to leg-up and the vessel on a different course
than the third leg. Notice the new direction of the
north-pointing arrow.
• Course-up or Heading-up (Hdg up) - Suppose that
you're displaying the charts as course-up or heading-up
and you press the cursor pad to go into browse mode. If
your vessel changes course, you won't see the chart turn
to the new direction until you return to vessel mode by
pressing the VESSEL key. You must be in vessel mode to
see any changed course angle. This feature lets you keep
a steady viewing angle if you're browsing around on the
chart.
• Leg-up - If you're displaying charts as leg-up and the 958
switches to a new leg, you'll see the chart rotate to the
direction of that new leg even in browse mode—unless
you're actively pressing the CURSOR PAD.
If you're displaying the charts as either leg-up or course-up, you may see
a black line with white space on the other side. This line is the edge of the
chart, which is now visible since the chart has been rotated. When the
vessel or cursor crosses the line, the display will switch to a new chart.
The edges of other charts in the 958's built-in world atlas are shown, in
addition to those in your local cartridge. These edges are shown as black
or red dashed lines.
The lat/lon grid is labelled only when the chart is north-up.
