958 Operator's Manual, Rev. A
The 958's CHART screen displays navigation data in an easily
recognizable, practical format: an overhead view of your
vessel's present position (or any position you choose) in
relation to land masses, nav aids, and your own defined
waypoints and routes. As you navigate, your vessel remains
centered on the CHART screen, and the chart moves
underneath your vessel.
The CHART screen's high-speed redraw feature means you
don't have to wait when you're scrolling from one location to
the next. The 958 automatically keeps the chart visible—even
as you move from one chart to the next. Move the cursor,
press a key, and you're still navigating through a channel,
around an island, or in open water—always in full view of
what's around you at all times.
Occasionally, you may see an hourglass symbol briefly
displayed on the screen while the 958 is changing or
redrawing the chart.
If your 958 is equipped with radar and/or echo sounder, you
can split the screen to show the chart, radar, and sounder
together in various combinations. In addition, you can overlay
a radar image on the chart and/or overlay a video image on
most screens. An introduction to these functions is given later
in this chapter. For details about the split screen, see "Splitting
the screen" starting on page 46.
The 958's large full-color screen is easily readable under all
conditions from full, direct sunlight to total darkness.
Anti-reflection treatment of the display and its window
eliminates over 90 percent of the reflection and glare usually
encountered in bright sunlight.
