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.

Focus Correction

When the lens is attached to the projector and images are being projected onto the screen, the

peripheral focus may be out of focus in some localized areas. If this happens, insert the one of

three kinds of spacers, in between the lens mounter and the projector unit to adjust the focus.

It is corrected in the direction where the position of the best focus in the part that corresponds

to the opposite angle at the position in which the spacer was inserted is near to the projector.

The corrected distance is determined by the thickness of the used spacers. As guide, the

distance is adjusted by approximately 120 mm for each 0.1-mm thickness of the spacers. It is

supplied for each 4 pieces with three kinds of spacers.
