CLEANING 
To 
get  the  brightest,  sharpest  screen  images,  keep  the 
optical system 
of 
your projector clean.  Dust 
or 
fingerprints 
on 
the  projection 
or 
condenser  lens  will  reduce 
th
e 
brightness of the screen  image and will cause  it to appear 
unsharp or low  in  contrast. 
Projection Lens 
Turn the focus knob clockwise until the lens 
is 
out 
as 
far 
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. 
With paper such 
as 
KODAK 
Lens Cleaning Paper 
or 
a soft, 
clean,  lintless cloth, gently wipe the 
front 
and rear surfaces 
of 
the  lens. 
If 
moisture  is  required,  breathe 
on 
the  lens 
surface 
or 
use  a  drop  of  cleaner  such 
as 
KODAK 
Lens 
Cleaner 
on 
the  paper  or cloth. 
Replace the lens 
by 
again  moving the focus knob toward 
the  side  of  the  projector  and  guiding  the  lens  back  into 
position.  Insert the lens 
far 
enough  into its recess 
so 
that 
the gear teeth 
on 
the side 
of 
the lens barrel will 
be 
engaged 
by 
the gear 
on 
the  focus· knob shaft.

al 
while out 
of

Turn  the  projector  bottom  side  up.  Open  the

as 
described 
on 
page  11.  Push  the 
LENS 
RETAINER 
down· 
ward  until 
it 
is 
free  of  its  retaining  clip;  then  raise  the 
retainer 
as 
far 
as 
it will 
go. 
Carefully 
lift 
out the 
CONDENSER 
LENS 
and  the 
HEAT'ABSORBING 
GLASS, 
and  gently place them 
on 
a soft cloth. 
Clean  both sides of the condenser lens and the heat·absorb· 
ing glass with 
KODAK 
Lens  Cleaning Paper 
or 
a soft, clean, 
lintless cloth. 
Be 
careful  not to leave  fingerprints 
on 
any of 
the surfaces. Replace the lens and  heat·absorbing glass in 
their 
original  locations,  with  the  flatter  side  of  the  con· 
denser lens toward the 
front 
of the projector. 
Gently clean  the  surface of the 
MIRROR 
with 
KODAK 
Lens 
Cleaning  Paper 
or 
a  soft,  clean,  lintless  cloth  moistened 
with
