●
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.
