If your projector is equipped with either of these
optional lenses, you can vary the size of the projected
image to fill a screen
without
changing the projector·
to·screen distance.
Using Zoom Lens
1. Install the zoom lens
by
moving the focus knob
toward the side of the projector and guiding the
lens into the projector. Insert the lens far enough
into its recess
so
that
the gear teeth
on
the lens
barrel will
be
engaged
by
the gear on the focus·
knob shaft.
2. Rotate the focus knob until the projected ima
ge
is sharp.
3. Rotate the
front
part of the lens barrel
until
the
image fills the screen.
4.
To
obtain maximum image sharpness and the
desired image size, you may need to repeat steps
2 and 3 alternately.
