WARNING
Do not block the WN-5220-S cooling fan or free air movement
under, over, or around the WN-5220-S. Loose papers or other
objects should not be nearer to the WN-5220-S than 6 inches
on any side.
CAUTION
Air handling ducts can discharge unwanted dust or high-
temperature air directly on the display. Do not operate the
WN-5220-S in dusty or high-temperature conditions.
CAUTION
Where several WN-5220-S displays are combined vertically,
installation of the top level requires a minimum of 16 inches of
clearance in order to position and fasten the display in place.
CAUTION
Some types of environmental lighting, such as incandescent, or
high-intensity discharge lamps such as metal halide or mercury
vapor lamps create high temperatures. This can cause
excessive heating of the display. The unit should be positioned
away from lighting to prevent heat buildup.
CAUTION
The front screen of the WN-5220-S display can be easily
scratched and the optical quality degraded by fingerprints.
Install the WN-5220-S in such a way that it is not exposed to
touching or possible scratching by hard objects.
