be ordered from Clarity Visual Systems, Inc. Use only the
projection lamp module specified by Clarity Visual Systems,
Inc. or an authorized Clarity Visual Systems, Inc. Service
center. Use of any other lamp voids the warranty.
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.
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.
Where several WN-5220-S displays are combined vertically,
installation of the top level requires a minimum of 12 inches of
clearance in order to position and fasten the display in place.
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.
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.
Display units with Ultra-Thin Mullion screens are not
serviceable from the front.
