The 961's CHART screens maximize usability by including
such features as an overhead view, fast chart redraw, an LCD
screen with easy-to-read numbers, and a plotter function for
up-close navigation.
Overhead view
The 961's CHART screens show navigation data in an easily
recognizable, practical format: an overhead view of your
present position (or any position you choose) from the air
"down" to your vessel, in relation to land masses, nav aids, and
user-defined waypoints and routes.
Chart redraw
Normally, as you navigate, your vessel remains centered on
the CHART screen, and the chart moves underneath it. The
961's high-speed screen redraw feature automatically keeps
the chart visible—even as you move from one chart to the
next.
Lighting
The 961's liquid crystal display (LCD) screen is easy to see in
all kinds of light—from full, direct sunlight to total darkness.
Anti-reflection treatment of the screen removes over 90 per-
cent of the reflection and glare usually found in bright sun-
light. Moreover, the screen is fully lit for nighttime use.
To adjust the screen's brightness, press the BRIGHTNESS key
(this key isn't labelled) to the left of the display screen. For
details, see "Brightness key" starting on page 3-26.
Plotter function
The 961's plotter function helps you navigate if you're ever in
areas that aren't represented on your installed navigational
