You
can remove a lens to replace it with a different lens.
Warning: Wait
at least 30 minutes to remove or replace the lens after turning off
the projector. Touching the lens unit before it cools down may
cause burns.
Caution:
Remove the lens only when necessary and
make sure the front of the projector is not facing up when you
remove the lens. This prevents dirt or dust from entering the
projector and lowering the projection quality. Avoid touching the
lens with your bare hands to prevent fingerprints on or damage to
the lens surface.
