SLIDE-NUMBER “0”
I
GATE INDEX
a. Place the tray of slides on the
AudioViewer/Projector with
slide number "0” at the gate
index. (If the tray does not seat
properly on the Audio Viewer/
Projector, remove the tray and
rotate the bottom metal plate
of the tray until the metal
plate locks into the "0”
position.)
b. Replace the tray on the Audio­
Viewer/Projector.
4. Turn on the AudioViewer/
Projector by moving the power
button to the ON position.
a. The projection lamp will
turn on.
b. The motor and fan will also
start but the built-in viewing
screen (or built-in front-projec­
tion lens) will remain dark be­
cause the dark-screen shutter
opens to allow the light beam
to project only when a slide is
in the gate.
5. Set the projection-lamp switch
(HI/ LO/EXT) to the low (LO)
position.
a. Low (LO) is normally used for
projecting images onto the
built-in viewing screen.
b. High (HI) is normally used for
a brighter image when project­
ing onto an external front
screen (using the built-in front-
projection lens). Using high
with the built-in viewing
screen will not damage the
AudioViewer/Projector, the
built-in screen, nor the slides.
c. The function of the external
position of the lamp switch
(EXT) is discussed on page 4,
under the heading, "Projec­
tion-lamp switch (HI/LO/
EXT),” and also under "Exter­
nal- projector interconnect
outlet.”
6. Press the slide-forward button
to advance the tray to a slide.
An image will appear on the
screen.
Using the Built-In Viewing Screen
Focusing the Image
7. Focus the image.
a. Model 570AF: Move the
AUTOFOCUS ON/OFF
SWITCH to the ON position. If
possible, focus on an open-
frame cardboard-mounted
slide, rather than on a glass-
mounted slide; the autofocus
mechanism will then focus
automatically on each slide
type, even when intermixing
cardboard, plastic, and metal
mounts (with the exception of
glass-mounted black-and white
slides).
h. Models 220, 270, and 470:
Manual focusing is normally
needed only once at the begin­
ning of the slide program if all
slide mounts are the same type.
If cardboard and glass-mounted
slides are intermixed, however,
refocusing for each mount type
may be necessary.
8. To magnify the image for
close-up study, press in and
lower the image-magnifying
lever.
a. The center portion of a 24 x
36 mm transparency is magni­
fied about 50 percent to fill the
built-in viewing screen.
h. Refocus the image. (The image
magnifier also works when pro­
jecting onto an external front-
projection screen.)
