Interfacing The 957 - NorthStar 957 Operator's Manual

Chapter 2 - Introducing the 957
Cleaning the display
screen
Pre-packaged moist tow-
ellettes (especially those
containing a small amount
of alcohol) are excellent for
cleaning the 957's display
window. You might want to
keep a supply on hand to
wipe off fingerprints and
other smudges.

Be careful when cleaning the glass window covering the
display screen. Although the window is scratch-resistant, you
may damage the anti-reflective coating if you use a dry cloth
to wipe dirt off. When wiping the window, always use a damp
cloth or a clean and dry microfiber-type lens cleaning cloth. To
dissolve any oil or grease on the screen, use a small amount of
window cleaner or alcohol.
If possible, try not to touch the window with your fingers. The
natural oils from your hand will temporarily affect the
characteristics of the screen and cause your fingerprints to
appear as bright reflections. These will disappear, however,
when you clean the screen as described above.
Excessive heat can cause short- and long-term damage to the
957. Although the 957 can recover from short-term effects,
long-term damage may be permanent. When the 957 is out in
the hot sun, but isn't being used, always use the protective
plastic cover.
If left disconnected and exposed, the 957's rear connectors
may corrode slightly from exposure to saltwater spray. If the
connectors are not in use, always keep their plastic caps on.
Protect the entire 957 from prolonged exposure to the
elements by mounting it, if possible, in a relatively dry
location. At the end of a trip, wipe the 957 dry.
The 957 can be connected to a wide variety of compatible
marine devices, including the Northstar 490 that adds
complete fishfinding capability to the 957. This type of
connection should be done by a qualified marine electronics
technician. For details, contact your local authorized Northstar
dealer.
