off. When wiping the window, always use a damp cloth or a dry,
clean, microfiber-type lens cleaning cloth. To dissolve any oil or
grease on the screen, use a small amount of window cleaner or
alcohol. Pre-packaged moist towelettes, especially those con-
taining a small amount of alcohol, are excellent for cleaning
the display screen. You may want to keep a supply handy for
removing fingerprints and other smudges.
Whenever possible, avoid touching the glass with your fingers,
since the natural oils of your hand will temporarily affect the
characteristics of the screen, causing your fingerprints to
appear as bright reflections. These will disappear, however,
when the screen is cleaned as described above.
To prevent moisture and dirt from entering the processor,
keep the CD-ROM drive's door and tray closed unless you're
inserting or removing a CD. Because the 961 copies and stores
CD data onto its internal hard drive, you'll only have to insert
these CDs during their installation. You shouldn't have to
open or close the drive for any other reason.
Keep all of your CDs in a safe, watertight place where they
won't be damaged or exposed to sunlight and any other kind
of heat.
You can interface the 961 to a variety of devices, including
autopilots, paper plotters (traditional navigation devices using
paper charts), radar plotters (navigation devices tracking radar
data as well as waypoints), fishfinders, instrument displays,
and personal computers.
The 961 features the following interface ports:
•
three independent output ports for driving NMEA-com-
patible devices
•
three input ports for accepting data from other NMEA
devices
•
an auxiliary (aux) port for either input or output of
SC-104 DGPS corrections and for uploading/downloading
waypoints, routes, or tracks to/from a personal computer
