CLEANING 
To 
get  the  brightest,  sharpest  screen  images,  keep  the 
optical system  of your projector clean. Dust or fingerprints 
on 
the  projection  or  condenser  lenses  will  reduce  the 
brightness of the screen  image and  will cause  it 
to 
appear 
unsharp or low 
in 
contrast.

as

as 
it 
will go.  Carefully move the focus  knob toward the side of 
the  projector 
as 
you 
withdraw  the  projection  lens.  Blow 
any dust or 
dirt 
from the lens.
