tance_

toward the side of the projector and guiding the
lens into the projector. I nsert the lens
far

t
he

the lens
barrel will
be
engaged
by
the gear
on
the focus-
knob shaft.
2. Rotate the focus knob unil the projected image
is
sharp.
3.
Rotate the
front
part of the lens barrel until the
image fills the
scceen
.
4.
To
obtain maximum image sharpness and the
desired image size, you may
need
to repeat steps
2 and 3 alternately.
