OPERATING CONTROLS
Slide Controls
Slide-focus knob: Turn this knob in
either direction to focus images.
With the Model 570AF, place the
autofocus on/off switch at the ON
position and focus the first image
only. Subsequent images will remain
in focus, even when using mixed types
of mounts, providing the autofocus
ON/ OFF switch is kept on.
Autofocus on/off switch: This
switch (Model 570AF only) must be
set at ON for the autofocus mecha­
nism to operate.
Slide-forward button: Press and re­
lease this button once to advance the
tray to the next slide. Hold it down to
advance the tray rapidly.
Pressing this button while the
AudioViewer/Projector is in the re­
cording mode (Models 270, 470, and
570AF) advances the tray and records
a 1000 Hz slide-advance pulse on the
projector-control track of the tape.
(See page 15 for information on the
tape-track configuration of the Audio-
Viewer/Projector, under the heading
"Magnetic Cassette Tapes.”
Slide-reverse button: Press and re­
lease this button once to reverse the
tray to the preceding slide. Hold it
down to reverse the tray rapidly.
NOTE: The slide-forward and
slide-reverse buttons can be
used during program playback
to resynchronize the images
with the audio track, if
necessary.
Power switch: Moving this switch to
the ON position provides power to the
entire Audio Viewer/Projector.
Slide-select button: When this but­
ton is held down (with power on), the
tray can be rotated by hand in either
direction to any slide for projection or
for editing, or to slide-number "0” for
tray removal.
Projection-lamp switch (HI/
LO/EXT): As noted previously. High
(HI) produces a brighter image and is
normally used when projecting slides
onto an external screen with the
built-in front-projection lens.
The low position of this switch (LO)
is normally used when viewing im­
ages on the built-in viewing screen
(front-projection door closed).
The external position (EXT) turns
off the projection lamp in the Audio-
Viewer/Projector and routes manual,
recorded, or timer-generated (Model
570AF only) slide-advance pulses to
an external slide projector (or dis­
4
solve control and two slide projectors)
linked to the external-projector inter­
connect outlet with an accessory
KODAK AudioViewer EC Intercon­
nect Cord.
Image-magnifying lever: When this
lever is lowered to its bottom position,
the center portion of a 24 x 36 mm
transparency is magnified by about 50
percent so the center portion of the
image fills the screen and small de­
tails in the center of the slide can be
seen more easily.
The normal (unmagnifying) posi­
tion of the image-magnifying lever
is up.
Images can be magnified while us­
ing the built-in viewing screen or
while projecting images onto an ex­
ternal screen using the built-in front-
projection lens. (Refer to page 9, un­
der the heading "How to Avoid Image
Cropping” for important information
on transparency formats and the
usable picture area.)
Variable electronic timer: The vari­
able electronic timer (Model 570AF
only) provides continuously variable
automatic slide advance pulses from
approximately 2 seconds at the fast
end (1) to 24 seconds at the slow end
(9). The slide tray on the Audio-
Viewer/ Projector (or on an external
slide projector or dissolve control con­
nected to the external-projector inter­
connect outlet) will cycle automati­
cally at any chosen interval from 2 to
24 seconds.
When using the variable electronic
timer to advance an external slide
projector or dissolve control (con­
nected to the external-projector inter­
connect outlet with an AudioViewer
EC Interconnect Cord), set the Audio-
Viewer/Projector projection lamp
switch at the external (EXT) position.
Move the variable electronic timer
control to off to resume manual or
taped slide advance.
Quick-locking elevation legs: As
noted previously, you can adjust the
Audio Viewer/Projector for proper im­
age height and leveling by pressing
down on both independently-adjust-
able latches while raising or lowering
the Audio Viewer/Projector to the de­
sired angle. When the image is in the
required position, release both latch­
es. The elevation legs will lock in
position.
Slide Control Outlets and Jacks
External-projector interconnect
outlet: This outlet accepts the plug of
a KODAK AudioViewer EC Intercon­
nect Cord (an accessory item de­
scribed on page 18). When the 3-posi-
tion lamp-control switch is set at the
external position (EXT), the Audio-
Viewer EC Interconnect Cord pro­
vides a path for manual, recorded, or
timer-generated (Model 570AF only)
slide-advance pulses from the Audio-
Viewer/Projector to an external slide
projector (or dissolve control and two
slide projectors).
To use the external-projector
interconnect outlet, the following
equipment is needed: a KODAK
EKTAGRAPHIC AudioViewer/
Projector, Model 220, 270, 470, or
570AF; a KODAK AudioViewer EC
Interconnect Cord; a slide projector
(such as a KODAK EKTAGRAPHIC
III E Projector) or a dissolve control
and two slide projectors (such as a
KODAK EKTAGRAPHIC Program­
mable Dissolve Control, Model 2, and
two KODAK EKTAGRAPHIC III E
Projectors.) You will also need a suit­
able sound-slide program (an AV cas­
sette tape recorded with narration
and 1000 Hz slide-advance signals)
and a tray of slides.
Using a Single External Slide Pro­
jector with the External-Projector
Interconnect Outlet
NOTE: Refer to the "User’s Op­
erating Instructions” packed
with your slide projector for de­
tails on projector operation.
1. Connect the 2-pin plug of the
KODAK AudioViewer EC Inter­
connect Cord (accessory item) into
the external projector (EXTER­
NAL PROJECTOR) jack on the
side panel of the AudioViewer/
Projector.
2. Then insert the 5-pin plug of the
AudioViewer EC Interconnect
Cord into the remote-control recep­
tacle of the external slide projector.
3. Set the projection-lamp switch of
the Audio Viewer/Projector at the
external position (EXT). If the pro­
jection-lamp switch is set at HI or
LO, the slide-advance mechanism
of the Audio Viewer/Projector will
advance instead of the external
slide projector.
4. Turn on the lamp of the external
slide projector and install the tray
