3
UV radiation from unprotected, operating bulb. Eye damage
injury. Do not disturb light path shielding from the bulb.
∇
WARNING
Only the WN-5220-V lamp, air filter, and fuse are user serviceable. Refer all other
service to a qualified service center. Failure to do so can result in electrical shock,
ultraviolet radiation burns, contact heat burns, serious injury, or irreparable
damage to the WN-5220-V.
∇
WARNING
The area around the projection lamp and the projection lamp assembly can become
extremely hot during and after use. Use extreme caution and let the WN-5220-V’s
lamp assembly cool for 5 minutes before touching or replacing the lamp assembly.
∇
WARNING
The WN-5220-V contains electrical interlocks that prevent operation when the
front screen or lamp access cover are removed. Do not bypass these interlocks,
except for servicing. Never operate the WN-5220-V with any access panels or the
front screen removed from the unit, except for servicing. Operating the WN-5220-
V with access panels or the front screen removed can expose service or operating
personnel to ultraviolet burns and high electrical voltages. Always wear
ultraviolet-blocking eyeware with side guards when servicing the WN-5220-V.
∇
WARNING
The WN-5220-V uses a high-intensity projection-lamp module. Do not attempt to
replace the projection lamp module with any alternative light source. Doing so
can cause overheating or unacceptable image quality. Use only the projection
lamp module specified by Clarity Visual Systems. Use of any other lamp voids the
warranty.
∇
WARNING
Do not block the WN-5220-V cooling fan or free air movement under, over, or
around the WN-5220-V. Loose papers or other objects may not be nearer to the
WN-5220-V than 6 inches on any side.
∇
CAUTION
Air handling ducts can discharge unwanted dust or high-temperature air directly
on VideoWall. Do not operate the WN-5220-V in dusty or high-temperature
conditions.

NOTE
Where several WN-5220-V VideoWalls displays are combined vertically,
installation of the top level requires a minimum of 16 inches of clearance to
position and fasten the VideoWall in place.
