ClearZoom™
ClearZoom is a feature that restores full brilliance and clarity
to a chart when it is zoomed. For details about using
ClearZoom, see "ClearZoom" starting on page 13-28.
There are various ways to customize the setup of your CHART
screen. The CHART SETUP screen includes options to
customize your chart display to meet your individual
navigation needs. For display setup information, including
how to set up the security system, see "Changing the display
setup" starting on page 13-2.
The usual display of your present position on the CHART
screen shows your vessel centered on the CHART screen. You
can immediately find your present position as it relates to your
desired track and any nearby waypoints, nav aids, land masses,
and so on. Your vessel remains centered on the chart, while
the chart moves underneath your vessel.
When the vessel moves near the edge of a chart, the 961/962
automatically switches to another available chart. If more than
one is available, the 961/962 tries to choose one that you've
marked as PREFER, or one that's about at the same zoom in/
zoom out level as the chart you'd been using. (For details
about marking charts as PREFER, see "Common chart
functions" starting on page 13-63.)
You can display your present position on the CHART screen at
any time by pressing the CHART key from within any
function. You're never more than one keypress away from
returning to the CHART screen.

screen:
