Software Version 2.6 Enhancements; Changing The Chart Screen's Orientation - NorthStar 961 User Manual

Software version 2.6 enhancements

This section describes several software enhancements made in
upgrading the 961/962 software version 2.5 to software version
2.6.

Changing the chart screen's orientation

You can now change the display of charts on the 961/962
&+$57 screen to any of the following viewing angles, regardless
of their original paper orientation:
CHART-up (This is the orientation of the original paper
•
chart. Previous software versions always used a Chart-up
orientation.)
COURSE-up (This is the orientation of your true course
•
during the last few seconds, as determined by the 961/962's
GPS receiver.)
LEG-up (This is the orientation of your desired track when
•
navigating, on a leg-by-leg basis, which provides a more
stable display than Course-up.)
NORTH-up (This usually is the same as Chart-up, but rotates
•
any charts that were originally skewed to fit a particular
coastline or harbor, so that true north is up on the CHART
screen.)
Once you set the desired chart orientation, the 961/962 automat-
ically adjusts the orientation angle as needed, according to the
currently viewed chart, or the course, or the trip leg. However,
whenever you've displayed the cursor on the CHART screen, in
order to retain precise positioning with the &85625 3$', the
961/962 temporarily inhibits any of these automatic changes in
the orientation angle. This does not mean that the chart-orienta-
tion feature isn't working. To re-enable any changes in
orientation, simply press the 9(66(/ key to remove the cursor
from the CHART screen.
When you rotate a chart by changing its orientation, all of the
original paper-chart information, such as labels of geographic
features and depth readings, are rotated along with the chart.
Also rotated with the chart are routes, tracks, the trip, and
