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 the
brightness of the screen image a
nd
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
KODAK
Lens Cleaning Paper (or equivalent)
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
KODAK
Lens Cleaner (or equiv·
alent)
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.
Condenser Lens, Heat-Absorbing Glass, and
Mirror
CAUTION: The heat-absorbing glass may shat-
ter
. Handle it only with gloves.
Keep
the glass
covered with a cloth
or
other material while
it
is
out
of
the projector.
Turn the projector bottom side up. Open the
LAMP
DOOR
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-
absorbing glass with
KODAK
Lens Cleaning Paper (or equiv·
alent) 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 condenser lens toward the
front
of
the
projector.
Gently clean the surface of the
MIRROR
with
KODAK
Lens
Cleaning Paper (or equivalent)
or
a soft, clean , lintless
cloth moistened with
KODAK
Lens Cleaner.
Close and fasten the lamp door.
