flashing an alarm icon on the screen. The 958 offers four
adjustable alarms, including anchor, cross-track distance,
arrival radius, and DGPS time-out. For details, see
"Understanding alarms" starting on page 144.
The 958's TIDE TRACK screen displays a 24-hour tide graph
for any of over 3,000 NOAA tide stations covering the entire
U.S. coastline, including Alaska and Hawaii, plus much of the
eastern and western Canadian coastline. You can display tides
for the current date or any other date. For details about
TideTrack, see "Understanding TideTrack™" starting on page
158.
The 958 offers a video display feature that lets you overlay an
image from a connected video source onto most of the 958's
display screens. You can also easily adjust the size, position,
and transparency of the image (that is, how much of the
underlying screen you can see through the video image). For
details, see "Using the video display option" starting on page
160.
To help retain the 958's best possible performance, Northstar
recommends following these suggestions:
•
keep the cartridge access door closed at all times, unless
inserting or removing a chart cartridge, to prevent
moisture and dirt from entering the 958
•
don't change the cartridge when the 958 is exposed to
water spray, rain, or moisture of any kind
•
keep spare cartridges in a safe, watertight place where
they can't be misplaced
•
keep fingerprints off the display screen (remove any prints
with a lens cleaning cloth)
•
remove dirt and grime with Windex and a soft cloth, or
else soap and water
