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 AudioViewer/
Projectors has four models: the Models 220, 270, 470, and 570AF.
The Model 220 is a minimiim-investment machine for playback of
synchronized sound-slide programs for almost any application in
which automatic slide projection with soimd 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/
Projector—the Model 570AF. It therefore describes in detail
features that your AudioViewer/Projector may not have.

recorded with an EKTAGRAPHIC
AudioViewer/Projector or
EKTAGRAPHIC AudioViewer can
be used.)
Preparing the AudioViewer/
Projector for Program Piayback
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.

STORAGE-DOOR LATCHES
3. Plug the AudioViewer/Prqjec-
tor into a grounded 120 V,
60 Hz power outlet.
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.
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 frontprojection 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 Image-Magnifying System
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 frontprojection screen.)

IMAGE-MAGNIFYING
LEVER
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.
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 openframe cardboard-mounted
slide, rather than on a glassmounted 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.
IMAGE IN MAGNIFIED MODE
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. To 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. To raise and level the image

the AudioViewer/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
he 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. Release the latches.
11. Reverse the tray to the
beginning of the program.

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 AudioViewer/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 AudioViewer/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 frontprojection 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 AudioViewer/ 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 AudioViewer/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-adjustable 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 AudioViewer EC Interconnect Cord pro
vides a path for manual, recorded, or
timer-generated (Model 570AF only)
slide-advance pulses from the AudioViewer/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
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 AudioViewer/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.
lì
To advance two slide projectors in
the dissolve mode, connect the acces
sory AudioViewer 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 AudioViewer/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
AudioViewer/Projector. This jack
also accepts the plug of a
KODAK
AudioViewer Tape Deck Remote Con
trol (an accessory item described on
page 18).

(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 AudioViewer/Projectors 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 AudioViewer 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.
• The tape pause/restart button is
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 highfrequency (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.
(For details on recording audio, refer
to "Recording the Program on the
Tape” on page 9.)
Cassette Tape Outlets, Jacks,
and Microphone
Remote-control outlet: This outlet
on Models 220 and 270 accepts t'he
plug of a KODAK AudioViewer/Pro-
jector Remote Control 210/260.
The remote-control outlet on Model
470 and Model 570AF accepts the plug
of the KODAK AudioViewer/Projector Remote Control 410/460. (The
functions of these accessory items are
described on page 18.)
Headphone outlet (EAR): Head
phones with a 1/4-inch plug (or adapt
er) can be used. (Audio is reproduced
monaurally.) Medium- to high-imped
ance headphones (150-2000 ohms) are
recommended. The internal loud
speaker and the external loudspeaker
jack are bypassed when the head
phone outlet is used. When using
headphones, adjust tone and volume
level as desired.
Microphone jack: This jack (on
Models 270, 470, and 570AF) accepts
the plug of the handheld microphone
supplied with the AudioViewer/
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 AudioViewer 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
enough to require the connection of
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 externalloudspeaker outlet!

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.
Number 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.

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

be surprised by how little effort is
needed to complete it.

Narration
MUSIC FADES UNDER AS NARRATION
BEGINS
It was a hot Sunday afternoon and we
decided to barbecue some steaks.
My son was in a rush to go out on a date
and asked me to start the fire.
1 plugged in the electric fire starter and
slipped it under the charcoal.
Usually we wait 15 to 20 minutes for the
fire to start.
My neighbor came over and we started
talking—it was a hot day; perfect for
bermuda shorts and no shoes or socks.
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. 1
told him to shower and the fire would be
ready.
But when 1 looked, the charcoal didn’t
seem to be lit.
... so 1 decided to hurry things up a bit. 1
got the gasoline can out and ... 1 have
to admit this was a real dumb thing to
do.
I’ve preached to my kids . . . never put
gasoline on a fire—but of course, 1
wasn’t thinking, just hurrying, and holy
mackerel . . .
Phoom! The whole thing exploded.
There was fire under the charcoal after
all. It shook me up so badly that 1 just
threw the gas can and . . .
... hit a nearby evergreen, setting it on
fire. Then the flames headed toward my
garage.
My neighbor came over and beat the
flames with some burlap while 1 ran for
the hose.
The can was kicked into the driveway
where it started.
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 AudioViewer/Projector 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.
Planning the Visuals
Now develop the visual side of the
script the same way you developed
the narration. Read through the
script (and listen to the "test tape”
you made). Make a list of all the
images that might work with the
script. Then go back over the list and
eliminate images that aren’t techni
cally feasible or that would be too
troublesome to shoot (because of dis
tant or difficult locations).
V
Type up the script with the com
mentary on the right side of the page
and the descriptions of the visuals on
the left (as shown on page 7, in "On
the Job Safety.”) It’s easier to type
this way. If you double or triple-space,
you’ll have room for the revisions you
may want to make later as you edit
the slides. When planning your slides,
be sure that no image remains on the
screen for too long.
Also remember that you have the
option of recording a program-pause
signal at any point in the program
(with Model 470 and Model 570AF)
for automatic tape stop. When the
tape automatically stops in response
to the recorded 150 Hz program-pause
signal, you can ask questions of the
audience, use the image-magnifying
feature to spotlight details in the
center portion of the slide, and
then resume the program when
appropriate.
If your script does not contain de
scriptions of the visuals, you can still
indicate where each slide change is
located in the program by inserting a
round dot (with a felt-tip pen) above
the words in the script that are spo
ken as the image changes. Then num
ber the dots consecutively.
Placement of Program-Pause
Signals in the Script
To show where program-pause signals
are needed in the script (using Models
470 and 570AF only), simply print
TAPE STOP (preferably in red ink).
Be sure to allow two seconds of
silence (unrecorded tape) before and
after each program-pause signal to
prevent tape slowdown and start-up
distortion of the recorded audio.
Editing, Arranging the Slides,
and Loading the Tray
1. Place your slides so that all im
ages and words are right-side up,
reading correctly from left to
right, and in correct projection
sequence (in the order that you
want them to appear in the show).
2. Review your slides. Is each slide
properly exposed, composed, and
focused? Are all important ele
ments in each slide legible? Is the
meaning of each slide readily ap
parent? Do the images fit together
visually and make logical sense?
Now is the best time to delete or
replace ineffective slides.
3. Rotate the remaining slides upside
down (so that all images are up
side down). Number each slide
mount consecutively in the upper
right-hand corner. (Do not use
sticky labels on the mounts. Pro
jector heat will loosen them, caus
ing the slides to jam in the gate.
Use a permanent ink felt-tip mark
er instead.)
4. Remove the lock ring or cover of
the tray by turning it counter
clockwise.
5. Be sure the bottom metal slide
retainer plate of the tray is locked
in the zero position. (Turn the
bottom metal plate of the tray
until it locks tightly.)
6. Insert the first slide into slot num
ber 1, the second slide into slot
number 2, etc. Remember: the cor
rect slide orientation for the AudioViewer/Projector is with the
image upside down and the cor
rect-reading side of the transpar
ency facing toward the next-higher
number in the tray.
7. Insert the slides into the tray in
exactly the same order and orien
tation as you arranged them (with
the images upside down).
8. Hold the full tray right-side up in
front of you. The mount numbers
on the slide mounts should be
positioned next to the outside cir
cumference of the tray and visible
as the tray is rotated.
9. Replace the lock ring or cover of
the tray.
10. Place the tray on the AudioViewer/Projector and advance
through the slides while checking
them for correct order and image
orientation on the screen.
11. Reset the tray to the beginning of
the program (so that slide-number
"0” is at the gate index).

How to Avoid Image Cropping
As you plan your slides, keep in mind that the more familiar you are with the
imaging requirements of the EKTAGRAPHIC AudioViewer/Projector (as with any
slide-display device having a built-in screen), the better you can prepare 2 x 2-inch
(135-format) slides that effectively communicate your message. Image legibility and
cropping are of prime importance with these communication devices.
Generally, you can use all of the transparency area of a 126-size slide. Horizontal
and vertical 135-size slides and 127-size super slides are cropped somewhat by these
display devices. About 3/64-incb (1.2 mm) of the long dimension (width) of a 135-size
slide is trimmed off each edge by the built-in screen. However, the narrow dimension
(height) of the slide will be visible.
Super slides lose about 1/4 inch (6.4 mm) of image height and width (3.2 mm at
each edge) when projected on the built-in screen of these machines. (It’s necessary
to crop some area from the larger formats so that images from the smaller formats
will not be too small for viewing.)
If you wish to fill the built-in screen of the AudioViewer/Projector completely,
one method is to use slides with a 30.8 mm square aperture. Slides with apertures of
this size are made by Kodak processing laboratories when
duplicates are ordered from superslides or from square transparencies made on
120- or 620-size film.
When projecting onto an external front screen (using the built-in front-projection
lens), the full picture area of all transparency formats (with the exception of 38 x 38
mm super slides that are vignetted when used with the short focal-length lens) will
be projected without image cropping.
We recommend that you shoot or select slides that have the same-size aperture
and same image orientation (all horizontal or all vertical formats).
All slides used with the AudioViewer/Projector are automatically registered
horizontally and vertically in both front- qnd rear-screen modes of projection.

Practicing the Program
(Before Recording It)
While reading the script, practice
pressing the slide-forward button (on
the AudioViewer/Projector or on the
optional KODAK AudioViewer/
Projector Remote Control 210/260 or
AudioViewer/ Projector Remote Con
trol 410/460) to record the slideadvance pulses (and to advance the
tray simultaneously). You may need
to press the slide-advance button a
second or so "ahead of schedule” so
that the images appear on the screen
exactly when they are supposed to.
(Slide-cycling time for the Audio
Viewer/Projector is about the same as
for most KODAK EKTAGRAPHIC
III and EKTAGRAPHIC Slide Pro
jectors—about 1 second.)
Recording the Program on the Tape
Although recording the audio track
and signal track of the program cas
sette tape at one time (in the same
recording "pass” of the tape) is possi
ble, it is not recommended. We recom
mend that you record the program
cassette tape in the following order:
1. Record the audio with the micro
phone.
2. Rewind the program tape to the
beginning. Disconnect the micro
phone. Place the tray of slides on
the AudioViewer/Projector.
3. Record the slide-advance pulses
(and program-pause signals with
models 470 and 570AF) while lis
tening to the audio, reading the
script, and pressing the slideadvance button (and pause/restart
button) as required.

Recording the Audio
1. Turn power on and insert a
blank cassette.
a. Play the program tape for about
8 to 10 seconds to get past the
unrecordable tape leader. Then
stop the tape with the tape stop/
eject button.
2. Record the script.
NOTE: Record in a room
in which you will not be
disturbed!
Put a sign on the door to make
sure you won’t be interrupted
during the recording session.
Disconnect the telephone and
close the windows. (The AudioViewer/Projector microphone
will pick up most noises in the
environment.) Also try to record
the entire script in one session
so the recording sounds consis
tent.
a. To put the Audio’Viewer/Projec-
tor in the recording mode, press
the tape play and tape record
buttons simultaneously. (The
tape will start recording when
you move the switch on the
microphone handle back to the
ON position.)
3. Press the tape pause/restart button
for about 1/2 second to record the
program-pause signal.
4. Allow the tape to play for two
more seconds and then stop it by
moving the switch on the handle of
the microphone to the OFF posi
tion. You can then start recording
the script.
b. Insert the plugs of the micro
phone into the microphone jack
and the remote tape-control
jack. The plugs will go in only
one way.
c. Move the tape-deck-motor
switch located on the handle of
the microphone to the OFF posi
tion so the tape doesn’t start
prematurely when you are
ready to begin recording.
The tape-deck motor switch prevents the tape
from running when the switch is at the OFF posi
tion.
10
b. When you are ready to record,
move the switch on the micro
phone back to ON, pause briefly
to let the tape reach proper
speed, and then narrate the
script into the microphone in a
normal speaking voice.
c. The red audio recording light
will flicker, indicating that your
voice is being recorded. The
built-in AGO (automatic gain
control) will keep the recording
level at an acceptable level.
For Models 470 and 570AF:
Recording a 150 Hz program-pause
signal immediately before the begin
ning of the program so the tape al
ways conveniently stops at the begin
ning of the program in the playback
mode will be helpful to you and other
program presenters. To do this:
1. Put the machine into the recording
mode by pressing the tape play and
tape record buttons simultaneously.
2. Let the tape run for several
seconds from the beginning.
Evaluating the Soundtrack and
Correcting Any Errors
Rewind and listen to the tape. Is the
sound level adequate—and consis
tent? Are there distracting back
ground noises? Is each word clearly
enunciated and correctly pro
nounced? Does the narration sound
like it was patched together from sev
eral recording sessions or does it flow
smoothly at the same playback level
from beginning to end? If you discov
er errors in your recording or if you
wish to make changes to it, change the
script first. Then:
1. Play the tape to any pause in
sound before the required record
ing change.
2. Record the new section, making
sure to avoid erasing good audio.
3. Stop, rewind, and listen to the cor
rected section.
How to Record the Slide-Advance
Pulses
IMPORTANT: To prevent
erasing the audio from the
tape while the AudioViewer/
Projector is being used to
record slide-advance pulses
(and program-pause signals
with Model 470 and Model
570AF), disconnect the
microphone.
When the microphone is discon
nected, slide-advance pulses and pro
gram-pause signals can be erased and
recorded without erasing your valu
able soundtrack. When the micro
phone is connected, both tape tracks
(audio on tracks 1 and 2, and slideadvance pulses and program-pause
signals on tracks 3 and 4) can be
erased and recorded.
1. Install the tray at "0.”
2. Play the tape past the initial pro
gram-pause signal (Models 470 and
570AF only).
3. Then stop the tape.
4. Put the machine into the recording
mode with the microphone discon
nected.
5. As the tape plays, read the script
and press the slide-forward button
(FORWARD) for about 1/2 second
at the points indicated in the
script. The tray will advance one
slide as each signal is recorded.
Reassuring "beeps” will be made
audible when recording slide-ad
vance pulses if the volume control
is raised slightly during recording.
(You won’t hear the "beeps” dur
ing tape playback.)
How to Record the Program-Pause
Signals (Models 470 and 570AF)
IMPORTANT: Do not record
the program-pause signals sepa
rately from the slide-advance
pulses. Record both types of sig
nals during the same "pass” of
the tape.
1. Press the tape pause/restart button
(PAUSE/RESTART) where the
words TAPE STOP appear in the
typed script. (The tape pause/res
tart light will not turn on when the
pause/restart button is pressed.)
2. The program tape actually stops in
response to recorded programpause signals only during tape
playback.
Evaluating the Slide-Advance
Pulses (and Program-Pause
Signals); Correcting Any Errors
Are all slides on the screen long
enough for viewers to see them and
read any text? Are some on the screen
longer than they need to be? Do some
images appear on the screen too late
(lag behind the narration)? Does the
tape stop when it is supposed to? If
the tape contains signal-recording er
rors, you can fix them without erasing
the audio.
1. Correct the script first.
2. Make sure the microphone is still
unplugged.
3. Play the tape to the pulses (and
signals) that need correction.
4. Stop the tape.
5. Put the AudioViewer/Projector
into the recording mode. (The au
dio will not be erased because the
microphone is still disconnected.)
6. As the tape plays, read the script,
listen to the recorded audio, watch
the images on the screen, and re
cord the new slide-advance pulses
(and program-pause signals). (The
tray will not advance, nor will the
tape stop, in response to old pulses
or signals because they are auto
matically erased as the tape is be
ing recorded.)
7. Be sure to stop the tape, with the
tape stop/eject button, before eras
ing good slide-advance pulses (or
program-pause signals).
8. Rewind the tape and check the
corrected section.
NOTE; If the program is short,
recording all of the slideadvance pulses (and programpause signals) from the begin
ning may be easier and more
effective.
Evaluating the Finished Program
You may need an outsider’s viewpoint
because after you’ve worked on an
audiovisual production, you may not
be able to judge it realistically.
Choose someone who is willing and
able to give you an honest opinion.
Chances are you’ll be dissatisfied
with some of the sequences in the
show, but remember that you may be
overly critical of your own efforts.
Perhaps all you need is one or two
new slides to replace marginal ones.
Recording Narration and
Background Music Simultaneously
Recording models of the AudioViewer/ Projector (Models 270, 470,
and 570AF) can be used with the
supplied microphone to record sound
from the built-in loudspeaker of a
radio, television, music playback
system, or other electronic source.
In this way, narration, background
music, and sound effects can be
recorded simultaneously with the
narration.
If your show is intended for sympa
thetic audiences within your organi
zation, you may not require a sound
track with anything more than narra
tion. However, you can often improve
the quality, appeal, and effectiveness
of your show by adding appropriate
music as background.
The easiest way to do this is to play
a tape containing the music over a
second cassette recorder located near
the microphone connected to the Au
dioViewer/Projector. By carefully
changing the volume of the external
tape recorder (i.e., the cassette ma
chine playing the background music),
an assistant can "fade up” or "fade
down” the background music as need
ed as you record the script. Thorough
rehearsal can produce an effective
sound track on your program tape.
Audio also can be recorded elec
tronically from an amplifier through
the AudioViewer/Projector micro
phone input with a special attenuat
ing connecting cord (available at ra
dio supply stores) that reduces signal
level to approximately microphone
level.
A separate cassette recorder can
also be used to record the audio for
your show on your program tape; the
slide-advance pulses (and programpause signals, with models 470 and
570AF) can be added to the program
tape later with the AudioViewer/
Projector.
IMPORTANT: Remember that
music and other copyrighted
materials cannot be recorded
without clearance from the
owner of the copyright.
11
Preventing Accidental
Erasures of Your
Program Tapes
With a suitable tool, break out the
plastic tabs from the edge of your
valuable recorded cassettes so the
tape cannot be accidentally erased
and recorded. With the tabs removed
from the edge of the cassette, the tape
record button (RECORD) cannot be
pressed in to put the AudioViewer/
Projector into the recording mode.
To erase and record the tape again,
cover the tab holes with pressuresensitive (cellophane) tape; then you
can record the cassette again.
Be sure to remove the cellophane
tape after recording the new program.
TABS
IN CASE OF DIFFICULTY
Slide Tray Jammed?
The AudioViewer/Projector is de
signed to stop to reduce the possibili
ty of damage if a bent slide is caught
(jammed) in the gate.

AudioViewer/Projector after a jam,
follow these steps:
1. Stop the program cassette tape by
pressing the stop/eject button.
2. Make a note of the number of the
slide in the gate.
3. Turn the large coin-slotted trayremoval screw (located in the hub
of the projector housing in the
center of the tray) in either direc
tion as far as it will go and then
remove the tray. (The tray-removal screw does not come out.)
Projection Lamp Burned Out?
(How to Change the Projection
Lamp)
CAUTION: Unplug power
cord from power outlet
before changing the lamp!
The lamp may still be hot!
Wear protective gloves!
Replace the projection lamp if the
screen remains dark (no image) when
power is on, the projection-lamp

replace the tray on the Audio
Viewer/Projector at the correct
slide number, and resume the
program.
6. Wipe off any fingerprints from the
lamp with a cloth moistened with
rubbing alcohol. (Avoid touching
the mirror on the lamp-access
door.)
7. Close the door, retighten the
screw, and plug the AudioViewer/
Projector in.
8. Turn the AudioViewer/Projector
on and advance the tray to a slide
to see if the image is projected on
the screen.
Tray Advance Unreliably?
Compact cassette slide-advance sig
nals and program-pause signals con
forming with spacing, frequency, du
ration, and level characteristics listed
under "Specifications” on page 17 will
operate the AudioViewer/Projector
dependably. Signals not conforming
to these specifications may result in
undependable operation. For example,
slide-advance signals of the correct
frequency (1000 Hz) but of the wrong
duration (other than 0.07 sec.) may
result in erratic slide-tray advance.
(Tapes made in conformance with
ANSI Standard PH7.4-1975 will oper
ate this machine dependably.)
Tapes recorded with earlier models
of the EKTAGRAPHIC AudioViewer
or EKTAGRAPHIC AudioViewer/
Projector will operate an
EKTAGRAPHIC AudioViewer/
Projector, Models 220, 270, 470, or
570AF dependably, and vice versa.
OWNER’S
MAINTENANCE
Cleaning the Built-In Tape Deck
If possible, clean the built-in tape
deck after every program. Cleaning
the tape deck takes only a few min
utes and helps prevent buildup of
oxide from tapes and loss of sound
fidelity.
1. Unplug the power cord!
2. Press the tape stop/eject button to
open the cassette well. Then par
tially close the cassette well door
to position the heads of the tape
deck for more convenient access
for cleaning.
3. Press and hold in the tape play
button to keep the tape heads
forward.
Rub the capstan, tape-guide path,
4.
and metallic heads with a cotton
swab moistened with head-clean
ing solution or isopropyl alcohol.
Do not touch the heads with any
metallic object. A head-cleaning
cassette (available at radio-supply
stores) can be used occasionally,
but a swab dipped in isopropyl
alcohol is preferred.
Cleaning the Built-In Viewing
Screen
Use a soft, damp cloth to clean the
built-in viewing screen. Do not use
lens-cleaning solutions or tissues con
taining silicone.
The optics and mirrors inside the
AudioViewer/Projector should be
cleaned only by a qualified techni
cian, such as those at a Kodak Ser
vice Center (addresses on back cover).
Partial disassembly of the Audio
Viewer/Projector is required for this
Adjusting the Position of the Image
on the Built-In Viewing Screen
All KODAK EKTAGRAPHIC AudioViewer/Projectors have been designed
to let the owner maintain, and make
minor adjustments to, the machine as
necessary.
The front mirrors have to be read
justed when the image on the built-in
screen is not in perfect alignment.
Adjustments are made with the
screws located on the front-projection
door. Be sure the image-magnifying
lever is located in its "up” position,
for normal (unmagnified) viewing
of images; then close the frontprojection door.

Adjustment of Lifter Height
The lifter returns the slide to the slide
tray. If adjustment is necessary
1. Remove the slide tray.
2. Pry off the black plastic cap cover
ing the screw.
3. A 0.050-inch Allen wrench is re
quired to turn the screw. Turning
it clockwise will cause the slide to
be lifted higher. Adjust the lifter
height so that the top of the slide
comes close to, but does not touch,
the bottom of the tray lock ring
when pressing the slide-select but
ton. (If the lifter is adjusted too
high, you will hear a noise as the
slides touch the ring. Readjust the
lifter as necessary.)
4. Replace the plastic cap on the
screw.
Aligning the Image-Magnifying
System
1. Make a slide for image positioning
as shown below.
+
2. Tape a 2 X 2-inch slide transparen
cy of poor quality (such as an
overexposed one) squarely over the
illustration.
3. Use a straight edge and pin to
scratch the surface.
4. Place this slide in the gate of the
AudioViewer/Projector.
5. Move the image-magnifying lever
down to the image-magnifying po
sition.
6. Remove the cap covering the
screw.
7. A 3/32-inch Allen wrench is need
ed. Slowly turn the screw to align
the central portion of the slide
with the screen. (The tray cannot
be on the AudioViewer/Projector
for this adjustment.)

Playing Continuously Repeating
Sound-Slide Programs
A silent or recorded endless-loop cas
sette having properly spaced slideadvance pulses can be used as a tim
ing device to advance a sound-slide
program designed to repeat continu
ously. Record slide-advance pulses (at
least 1 1/2 seconds apart) on the end
less-loop cassette at the intervals de
sired. Short endless-loop cassettes are
preferred. Be sure to use only the type
that have sprocket teeth on the hub of
the take-up reel. Clean the metal heads
and tape-guide path in the built-in
cassette machine often because these
tapes are heavily lubricated.
Model 570AF: We suggest using
the built-in variable-electronic timer
as the timing device to advance the
continuously repeating program in
stead of an endless-loop cassette.
Some Sources of Endless-Loop
Compact Cassettes Designed
to be Played in the Vertical
Plane
Compact-cassette format continuousloop tapes are usually designed to be
played in the horizontal plane, label
up. However, owners and users of the
EKTAGRAPHIC AudioViewer/
Projector interested in producing
and presenting continuously repeat
ing sound-slide programs may want
to purchase continuous-loop cas
settes designed to be played vertical
ly. Two firms marketing such cas
settes are:
• Visual Horizons, Inc.
180 Metro Park
Rochester, NY 14623
• Mann Endless Cassette Industries
P.O. Box 1347
3700 Sacramento St.
San Francisco, CA 94101

Stereo Music Tapes
Cassette tapes that have audio record
ed on all four tracks (such as those
sold for playback on home cassette
players) will trigger sporadic and un
wanted slide advances (and program
pauses, with Models 470 and 570AF).
Tapes having no audio recorded
on tracks 3 and 4 (such as those
recorded with an EKTAGRAPHIC
AudioViewer/Projector or with most
audiovisual cassette recorders) can be
played satisfactorily.
15
Using a KODAK EC
Remote Control with
an EKTAGRAPHIC
AudioViewer/Projector
A KODAK EC-1, EC-2, or EC-3 Re
mote Control (normally intended for
use with KODAK EKTAGRAPHIC
III and EKTAGRAPHIC Slide Pro
jectors) can be connected to the re
mote-control outlet of an Audio
Viewer/Projector and used to
remotely advance and reverse the
tray. (The EC Remote Control can
also be used to record slide-advance
pulses when using the Models 270,
470, or 570AF).
If the KODAK EC Remote Control
has a focus switch, it can be used to
pause and restart the program tape
during recording and playback and to
record program-pause signals (with
Models 470 and 570AF). (The focus
switch on the EC Remote Control will
not provide remote-focus capability.)
Accidentally pressing the focus
switch on the EC Remote Control in
both directions while recording a pro
gram-pause signal on the tape may
record an improper signal.
