LNS-W20/LNS-W21/LNS-S20/LNS-T20/LNS-T21
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-W21 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.
