•  Do not shake or place excessive pressure on the projector or the lens compo-

nents as the projector and lens components contain precision parts. 

•  When shipping the projector with the optional lens, remove the optional lens 

before shipping the projector. The lens and the lens shift mechanism may en-
counter damage caused by improper handling during transportation. 

•  Before removing or installing the lens, be sure to turn off the projector, wait 

until the cooling fans stop, and turn off the main power switch. 

•  Do not touch the lens surface when removing or installing the lens. 
•  Keep fingerprints, dust or oil off the lens surface. Do not scratch the lens sur-

face. 

•  Work on a level surface with a soft cloth under it to avoid scratching. 
•  If you remove and store the lens, attach the lens cap to the projector to keep 

off dust and dirt. 

Pull out the lens cap.
