Lens  installation  and  replacement  should  be  made  by  the  qualified 

service personnel.

Do  not  give  a  shock  or  excessive  load  to  the  projector  or  the  lens 

components  as  the  projector  and  lens  components  contain  precision 

parts.

When transporting the projector with the lens, remove the lens before 

transporting the projector. The lens and the lens shift mechanism may 

be damaged 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 surface.

Work on a level surface with a soft cloth under it to avoid scratching.

If  you  remove  and  store  the  lens,  attach  the  lens  hole  cover  to  the 

projector to keep off dust and dirt.

When using the LNS-W52 lens unit, set the lens shift adjustment to the 

center of the screen. Otherwise, the edges of the screen may  become 

darker or shadows may appear.
