INTRODUCTION
Congratulations on the purchase of your new KODAK
EKTAGRAPHIC AudioViewer/Projector.
Please study this instruction manual. Knowing how your Audio¬
Viewer/Projector works will help you to communicate your message
to your audience more effectively.
The current family of KODAK EKTAGRAPHIC AudioViewerI
Projectors has four models: the Models 220, 270, 470, and 570AF.
The Model 220 is a minimum-investment machine for playback of
synchronized soimd-slide programs for almost any application in
which automatic slide projection with sound for an individual or a
small group is required.
The Model 570AF provides additional features for maximum equip¬
ment versatility, such as autofocus capability and a variable
electronic timer for silent automatic slide advance.
The Models 270 and 470 offer a range of features in between these
two models to satisfy your particular needs.
IMPORTANT: This instruction manual explains all of the
operational features of our top-of-the-line AudioViewer/
Piojector—the Model 570Ar. It therefore describes in detail
features that your AudioViewer/Projector may not have.
To become familiar with the features provided by your Audio-
Viewer/ Projector, and to make this instruction manual as useful to
you as possible, scan the list of features under “Standard Features of
the Current Line of KODAK EKTAGRAPHIC AudioViewer/
Projectors;” then study the “Feature Comparison Chart— K ODAK
EKTAGRAPHIC AudioViewer/Projectors” so that you will be able to
identify the instructions that apply to your machine. (For your
convenience, specific AudioViewer/Projector models are identified in
the instructions, where appropriate.)

OPERATING
INSTRUCTIONS
To play back a sound-slide pro¬
gram with your KODAK
EKTAGRAPHIC AudioViewer/
Projector, follow the steps listed
below:
You will need a program recorded in
conformance with ANSI Standard
PH7.4 —1975. (Any program
recorded with an EKTAGRAPHIC
Audio Viewer/Projector or
EKTAGRAPHIC AudioViewer can
be used.)
Preparing the AudioViewer/
Projector for Program Playback
1. Place the AudioViewer/
Projector on a sturdy support.
(The rubber feet are nonmarring.)
2. Turn the storage-door latches
on the back of the Audio-
Viewer/Projector counter¬
clockwise and open the storage
door from the top.
a. Uncoil the permanently at¬
tached power cord and run it
through the slot of the storage
door.
b. Close the storage door and re¬
lock both latches.
POWER CORD
3. P lug the AudioViewer/Prqjec-
tor into a grounded 120 V,
60 Hz power outlet.
1

SLIDE-NUMBER “0”
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. T urn 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.
Using the Built-In Viewing Screen
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.
Focusing the Image
7. F ocus 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).
b. 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.
Using the Image-Magnifying System
8. T o 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.
b. Refocus the image. (The image
magnifier also works when pro¬
jecting onto an external front-
projection screen.)

Using an External Front-Projection
Screen
NOTE; For optimum image
brightness and quality, the sug¬
gested distance between the exter¬
nal front-projection screen and
AudioViewer/Projector is 3 to
12 feet (0.91 metre to 3.7 metres).
9. T o project onto an external
screen:
a. Place the projection-lamp
switch at high (HI) and move
the front-projection door to the
right. This will expose the per¬
manently installed 77 mm //3.5
front-projection lens.
b. Refocus the image on the exter¬
nal screen.
Raising and Leveling the Image
10. T o raise and level the image
a. Press and hold down both inde¬
pendently adjustable elevation
latches.
b. Raise and adjust the front of
the Audio Viewer/Projector to
the desired angle.
Using the Built-in Cassette Machine
12. Press the tape stop/eject
button (STOP/EJECT) to open
the cassette well.
IMPORTANT: Unlike most cas¬
sette machines, the AudioViewer/
Projector requires the cassette to
be oriented so that
a. The full reel of rewound tape
on the supply reel is located on
the bottom—not at the top.
(The empty takeup reel is
located on top.)
b. The open-tape side of the cas¬
sette faces forward (toward
you).
c. Side A of the tape faces away
from the machine.
FRONT-PROJECTION DOOR
c. R elease the latches.
11. R everse the tray to the
beginning of the program.
Press the slide-reverse button un¬
til slide-number "0” is at the gate
index.
Suggested front-projection distance is 3-12 feet.
13. Insert the Cassette into the
Cassette Well.
a. Orient the cassette as de¬
scribed above and gently press
the cassette into the cassette
well; then close the cassette-
well cover.
b. Press the tape-play button. The
tape will start playing.

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
Audio Viewer/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 AudioViewer/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¬
solve control and two slide projectors)
linked to the external-projector inter¬
connect outlet with an accessory
KODAK Audio Viewer 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/Projec tor 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
4

on the external slide projector.
Align and focus the image. Then
reset the tray at the beginning of
the program.
5. Play the program-cassette tape in
the Audio Viewer/Projector. As the
cassette tape plays, the external
slide projector will advance in syn¬
chronization with the 1000 Hz
slide-advance pulses recorded on
the control track of the program
cassette tape.
Using a KODAK EKTAGRAPHIC
Programmable Dissolve Control
(and two Slide Projectors) with the
External-Projector Interconnect
Outlet
NOTE: Refer to the ’’User’s
Operating Instructions” packed
with your Programmable Dis¬
solve Control for details on dis¬
solve control operation.
To advance two slide projectors in
the dissolve mode, connect the acces¬
sory Audio Viewer EC Interconnect
Cord to the REMOTE receptacle
located on the back panel of the
KODAK EKTAGRAPHIC Program¬
mable Dissolve Control, Model 2. The
Programmable Dissolve Control will
advance at a 1-second rate each time
it receives a slide-advance pulse from
the Audio Viewer/Projector.
Be sure to connect and operate the
equipment before a scheduled show¬
ing. A thorough rehearsal is good
audiovisual practice.
Remote tape-control jack: This
jack (provided on Models 270, 470,
and 570AF), accepts the smaller of the
two microphone plugs supplied on the
Audio Viewer/Projector. This jack
also accepts the plug of a KODAK
Audio Viewer Tape Deck Remote Con¬
trol (an accessory item described on
page 18).
Cassette-Tape Controls and
Visual Indicators
Tape-recording button: To put the
Audio Viewer/Projector into the re¬
cording mode (using Model 270, 470,
or 570AF), simultaneously press this
button (RECORD) and the tape play
button (PLAY).
For details on recording a sound-
slide program, refer to page 9, ’’Re¬
cording the Program on the Tape.”
Tape-forward button: This button
(FORWARD) advances the tape rapid¬
ly onto the top take-up reel of the
cassette.
Tape-rewind button: Press this but¬
ton (REWIND) to rewind the tape
rapidly onto the bottom supply reel of
the cassette.
Tape-play button: Press PLAY to
play the tape. The normal playing
speed is the same as for most cassette
machines intended for home use—
1 7/8 inches per second. When this
button is pressed simultaneously with
the record button, recording models
of the Audio Viewer/Projector (Mod¬
els 270, 470, and 570AF) are put into
the recording mode.
Tape stop/eject button: With any
tape-control button depressed, press¬
ing this button once stops the built-in
tape machine. Pressing it twice un¬
latches the cassette-well cover so the
cassette can be inserted or removed.
(With no tape-control buttons de¬
pressed, the first actuation of the tape
stop/eject button unlatches the cas¬
sette-well cover.)
Tape pause/restart button: Press¬
ing this button (PAUSE/RESTART)
in the recording mode (Models 470
and 570AF only) records a 150 Hz
program-pause (tape-stop) signal on
the tape. (The tape does not stop as
the signal is being recorded, howev¬
er.)
Tapes stopped in the playback mode
by recorded program-pause signals
(using Models 470 and 570AF) can
also be restarted with this button.
This button can also be used during
tape playback to stop and restart the
tape at any point in the program.
Models 220 and 270 will ignore (run
by) recorded 150 Hz tape-stop signals
because these Audio Viewer/Projec¬
tors are not provided with pause/res¬
tart circuitry. However, you can stop
the tape manually. To stop and restart
the tape at the points in the program
indicated in the script, simply press
the tape stop/eject button to stop the
tape; press the tape play button
(PLAY) to restart the tape when de¬
sired.
The cassette tape deck in the Model
270 can also be stopped and restarted
with a KODAK Audio Viewer Tape
Deck Remote Control. See page 18 for
a description of this accessory item.)
Tape pause/restart light (Models
470 and 570AF): This light brightens
when:
• The tape is stopped by a recorded
150 Hz program-pause signal, dur¬
ing program playback.

pressed to stop the tape in the play¬
back mode.
• The tape deck motor switch (located
on the handle of the microphone
supplied with Models 270, 470, and
570AF) is moved to the OFF posi¬
tion, or the tape deck motor switch
on the accessory AudioViewer Tape
Deck Remote Control is placed at
the OFF position. The tape pause/
restart light goes off when the tape
is restarted.
Tone: This control decreases high-
frequency (treble) response as it is
moved down from the top position.
Adjust it for best sound. It is inopera¬
tive during recording.
Volume control: Moving this con¬
trol up increases sound level during
program playback. Moving the con¬
trol down decreases volume.
This control does not affect record¬
ing level.
Signal-recording light: This green
light (on Models 270, 470, and 570AF)
stays on (brightens) when the Audio-
Viewer/Projector is being used to re¬
cord 1000 Hz slide-advance pulses and
150 Hz program-pause signals. (Re¬
cording of slide-advance pulses and
program-pause signals is normally ac¬
complished when the AudioViewer/
Projector is in the recording mode
with the microphone disconnected. Re¬
fer to page 10, ”How to Record the
Slide-Advance Pulses,” and ”How to
Record the Program-Pause Signals.”
Any previous slide-advance pulses
or program-pause signals recorded on
the control tracks of the program
cassette tape will be erased if the tape
is running while the signal-recording
light is on.
Audio-recording light: This red
light (on Models 270, 470, and 570AF)
’’flickers” when sound is being record¬
ed with the microphone.
Sound already recorded on the tape
will be erased if the tape is running
while the audio-recording light is on.

Models 270, 470, and 570AF) accepts
the plug of the handheld microphone
supplied with the Audio Viewer/
Projector.
The small remote tape-control jack
(located next to the microphone jack
on Models 270, 470, and 570AF) also
accepts the plug of a KODAK Audio-
Viewer Tape Deck Remote Control
(an accessory item described on page
18) for manual remote control of tape
stop/ start during recording and
playback.
External-loudspeaker outlet
(SPK): An external loudspeaker hav¬
ing a nominal impedance of 8 to 16
ohms can be connected to this outlet
with a 1/4-inch phone plug.
An external loudspeaker should be
considered when the audience is large

an external slide projector (or dis¬
solve control and two slide projectors)
to the external-projector interconnect
outlet for projection on an external
screen.
The internal omnidirectional loud¬
speaker is automatically disconnected
when an external loudspeaker is con¬
nected to the external-loudspeaker
outlet.
CAUTION: Do not connect
headphones to the external-
loudspeaker outlet!
Omnidirectional handheld micro¬
phone: This microphone (provided
with Models 270, 470, and 570AF) is
used for recording narration and
sound effects. (For more details about
recording audio, refer to *'Recording
the Program on the Tape,” on page 9.)

PREPARING NEW
SOUND-SLIDE
PROGRAMS
(Models 270, 470, and 570AF)
Writing the Outline, Writing the
Script, and Planning the Visuals
The following information applies
only to recording models of the
AudioViewerI Projector: Models
270, 470, and 570AF,
Preparing a new sound-slide pro¬
gram with the KODAK
EKTAGRAPHIC AudioViewer/
Projector is challenging—and fun! If
you’ve never done much writing be¬
fore, the prospect of turning out an
entire script may make you nervous.
If so, relax. Writing is easier if you
tackle he job in stages and allow
enough time.
We suggest novice producers write
the narration first, before they consid¬
er the visuals to illustrate it.
Gathering and Organizing
Your Ideas
Hold a brainstorming session and
write down as many ideas for your
script as you can think of. Use a
3 X 5-inch card for each idea. Review
all of the cards and determine five or
six major subject headings that cover
all your ideas.
Writing the Outline
Next, organize the cards under the
major headings and discard redun¬
dant cards. Add new ones as you
think of new ideas. Now put the cards
in order. This will give you a good
start on the first draft of the outline.
Nximber the cards so they can be
easily rearranged in correct order if
they are dropped. Writing the outline
should be easy if you follow the order
of the cards. Leave five or six blank
lines between each major heading (to
be filled in later with more detailed
information).
When you’re satisfied with the out¬
line, you may want to give your super¬
visor, co-workers, or sponsors a copy
to make sure that they agree with the
creative approach and the content
that you plan to cover.

2. Person with charcoal grill.
It was a hot Sunday afternoon and we
decided to barbecue some steaks.
3. Two people talking.
My son was in a rush to go out on a date
and asked me to start the fire.

5. CU—Charcoal/starter.
Usually we wait 15 to 20 minutes for the
fire to start.
6. Two people dressed
My neighbor came over and we started
in shorts.
talking—it was a hot day; perfect for
bermuda shorts and no shoes or socks.
7. CU—Son at door.
Then my son came to the door, asked
how the fire was coming, and said that
he was in a hurry and had to get going. I
told him to shower and the fire would be
ready.
8. LS—Father at charcoal.
But when I looked, the charcoal didn’t
seem to be lit.
9. CU—Father picking up.
... so I decided to hurry things up a bit. I
got the gasoline can out and ... I have
to admit this was a real dumb thing to
do.
10. CU—Pouring gas on.
I’ve preached to my kids . . . never put
gasoline on a fire—but of course, I
wasn’t thinking, just hurrying, and holy
mackerel . . .
11. MS — G as explosion in grill.
Phoom! The whole thing exploded.
There was fire under the charcoal after
all. It shook me up so badly that I just
threw the gas can and . . .
12. LS — B urning gas can

and bushes.
fire. Then the flames headed toward my
garage.
13. LS — M an extinguishing fire.
My neighbor came over and beat the
flames with some burlap while I ran for
the hose.
14. LS — F oot kicking gas can.
The can was kicked into the driveway
where It started.
Writing the Script
Now add as much relevant detail as
you can in the space under each head¬
ing and then turn the points you’ve
listed into sentences. If you have trou¬
ble finding the right words, ask your¬
self, what am I really trying to say?
When you can answer that question
in a simple sentence, write it down.
When you’ve finished the first
draft, put it away for a few days.
When you pick it up again, you may
be surprised by how little effort is
needed to complete it.
Remember that the audience watch¬
ing your slide show will not be able to
see your paragraphs and punctuation.
You have to write for their ears. Use
short, easily-understood sentences.
Avoid unusual words, technical
terms, and jargon. Remember: clarity
comes from little words.
When you’re satisfied with your
script, record a ''test tape” of the
script with the Audio Viewer/Projec¬
tor and play it back to hear how it
sounds. This serves as a double check.
If you can read the narration aloud
with no difficulty, you or the narrator
you choose should be able to read it
easily too. If the people you ask to
listen to the tape understand it,
chances are your audience will
understand the final production tape
as well.
