you place the set in your home, can affect your color
picture. So you may wish to make a few simple
adjustments. Zenith has made this easy to do. In fact,

FIRST THINGS FIRST
LOCATION
Put your TV set where sunlight or bright light will not fall
directly on the screen. Allow a comfortable viewing
distance, usually six feet or more.
ANTENNAS
To get the best color picture, you must have a good
antenna system. See pages 11 and 12 on antennas.
VENTILATION
Proper ventilation helps keep your set running cool. On
the back and bottom of every set, there are slots, ora
perforated screen, which permit a flow of air to the set.
DO NOT ENCLOSE THE CABINET OR OTHERWISE
OBSTRUCT VENTILATION AT THE BACK OR BOTTOM.
POWER
Your set is designed to operate on 120 volt 60 Hertz AC.
DO NOT ATTEMPT TO OPERATE YOUR SET ON DC.
The power cord of your TV set has a polarized plug as
required by Underwriters’ Laboratories. This plug has one
regular blade and one wide blade. It will fit only one way
into the standard electrical outlet. If the blades will not
enter your outlet, try reversing the plug. If the blades will
not enter either way, your outlet is probably many years
old and is non-standard. In that event, a new outlet
should be installed by a qualified electrician.
WARNING :
DO NOT EXPOSE THIS TV SET TO RAIN OR MOISTURE.
NEVER OPERATE THE SET IF LIQUID HAS
ACCIDENTALLY SPILLED INTO IT. If this happens, have
your set checked by a service technician before using it
again. Fire or electric shock could result. For additional
points on safe operation of your set, see the Safety
Tips folder.
VIDEO GAMES
CAUTION: If you use your TV set to play video games,
avoid setting the PICTURE CONTROL (brightness) for an
excessively bright game display. The reason for this is
that a bright, fixed pattern such as “tennis court’ lines, if
used for long periods of time, can imprint the pattern
permanently on the TV picture tube. You can reduce this
possibility by alternating use of the game with normal TV
viewing, by turning the brightness down when playing
video games, and by turning off the game promptly
after using it.
WHEN ON VACATION
When you are going away on vacation, or don’t plan to
use your Set for a long time, we suggest you unplug your |
set from the wall outlet. If your set is connected to an
outdoor antenna, we also suggest you disconnect the
lead-in wires at the back of your set.

HOW TO SETUP AND FINE-TUNE
VIF AND URF CHANNELS
TOUCH-COMMAND CHANNEL SELECTION
Zenith’s 14-position Touch-Command Channel
Selection System makes channel selection easy. After you
complete the simple setup and fine-tuning steps, you can
select up to 14 VHF and UHF channels with just the touch
of a button. Channel change is instant and direct. To
change channels, lightly press the proper button. There is
no need to fine-tune each time you change channels—
not even on UHF channels!
The control panel to the left shows you where to find the
controls you need. Open the panel door at the right
side of receiver for access to the controls. Remove Dial
Scale Cover Panel for access to Dial Scales and Fine
Tuning Controls. Follow these steps:
1. Hook up your VHF and UHF antennas.
(See antenna section on pages 11 and 12.)
2. Plug in your set. (See page 3.)
3. Push the ON-OFF switch to turn the set ON and allow
it to warm up for two or three minutes. (To turn the set
OFF, just push the ON-OFF switch again.) The COLOR
SENTRY control can be set either ON or OFF while you
are fine-tuning the color picture.
4, AFC (AUTOMATIC FINE-TUNING CONTROL)
IMPORTANT: Set the AFC switch to the OFF position
and leave it in the OFF position while fine-tuning
each channel. 3
5. Twelve of the fourteen positions in the channel selector
have been preset for you at the factory with VHF
channels in a sequence 2 through 13. However, signal
conditions vary from station to station. To compensate
for this, each VHF channel available in your area should
be fine-tuned to give you the sharpest possible picture.
These VHF channels (2-13) can be left as set up at the
factory or rearranged in any order whicli you find
convenient. It is not possible to preset UHF channels
(14 through 83) at the factory because different areas of
the country have different UHF channels available. The
U1 and U2 positions can be used for VHF and/or UHF
channels. Also, UHF channels (14-83) may be set up on
any unused VHF position.
6. To set up a Channel, you first remove the tab you wish
to replace. You do this by pushing back on the exposed
part and pulling to the RIGHT. Then insert the VHF or -
UHF channel tab which you have selected.
NOTE: UHF channel number tabs are supplied on a
separate sheet and must be inserted before you can
tune a UHF channel.

7. When you have
inserted the proper
VHF or UHF channel
tabs, use the Perma-
Set fine-tuning
control, dial scale
and dial scale pointer to fine-tune the channels. These
controls are located to the right of the channel tab.
Select the channel you want to fine-tune by pushing
the proper channel selector button (located at the left
of the channel number). The channel number will
then be illuminated.
. Using the dial scale pointer as a guide, turn the
Perma-Set Fine-tuning control (located at the right
side of the dial scale) to locate the channel you want.
The upper numbers on the dial scale are for VHF
channels, the lower ones for UHF channels.
To fine-tune this channel, turn the Perma-Set Fine-
tuning control first in one direction, then in the other,
until you get a sharp, clear picture. If you turn the knob
too far to the left, the color picture goes to black-and-
10.
11.
12.
white. If you turn it too far to the right, the color picture
breaks up into wavy lines. You’ll find the sharpest,
clearest picture at a point just before the picture
starts to break up.
. Repeat steps 4, 5, 6, 7 and 8 for each VHF and UHF
channel you wish to receive.
Replace the dial scale cover panel.
Close the control panel door. Now that you have the
channels set up, all you have to do to choose the
channel you wish to view is to touch me button at the
left of the channel indicator.
REMEMBER: Whenever you wish to change the
channel settings, always repeat steps 4, 5, 6, 7 and 8.
When you are satisfied with the VHF-UHF fine-tuning
on all channels, turn the AFC switch ON and leave it
ON. This “locks” in the tuning to each channel, so that |
every time you change channels, you'll get a clear,
sharp picture.
NOTE: In some cases where TV signals are not normal,
you may get a better picture with the AFC switch OFF.
If you get a better picture with the AFC switch OFF,
leave it OFF.

HOW TO GET A GOOD COLOR PICTURE
WITH COLOR SENTRY ON
Your COLOR SENTRY system has been designed to
provide an excellent color picture, automatically, under
typical viewing and telecast conditions. However, because
TV signals vary in different localities, and because
people’s preferences differ, your new Zenith Color TV
lets you make additional adjustments if you wish.
To make sure the COLOR SENTRY gives you the kind of
picture you want, follow these steps:
1. Push the ON-OFF switch to turn the set ON and allow
it to warm up for two or three minutes.
2. Select a channel that is telecasting in color.
3. Be sure that your set is properly fine-tuned. ae
fine-tuning section on pages 5 and 6.)
4, Push the COLOR SENTRY control to the ON position
(a bright yellow color will show in the control). This
should give you an excellent color picture. If this isn’t
the picture you want, follow steps 5 through 9.
. Turn the PICTURE control to an approximate mid-range
position.
6. Now turn the BLACK LEVEL control to the middle, or
7.
detent, position. This position will usually assure that
areas of the picture which should be black are black.
Turn the PICTURE control in either direction to get the
brightness level you want.
. If the dark areas and colors appear faded or washed-
out, the BLACK LEVEL control should be turned to the
left. If light backgrounds and colors appear too dark,
it should be turned to the right.
. We recommend you set the SHARPNESS control in the
mid-range, or detent, position. If you prefer a softer
picture, turn the control to the left. Turn it to the right
for a sharper picture.
For a wider range of color tuning adjustments, tune the
color picture with the COLOR SENTRY control OFF.
(See next page.)
NOTE: If you still don’t get a good picture after fine-tuning
and following the above steps, check your antenna
system. (See antenna section on pages 11 and 12.)

HOW
TO
GET
A
GOOD
COLOR
PICTURE
WITH COLOR SENTRY OFF
The preceding page tells how to get a good color picture
with the COLOR SENTRY control ON. But there may be
times when you will want to make even more adjustments.
You can do this with the COLOR SENTRY control OFF.
This is because, with the control OFF, the COLOR LEVEL
and TINT controls can be adjusted and the PICTURE
control has a wider range of adjustments. Just follow
these steps:
1.
Turn your set on and allow it to warm up for two or
three minutes. Push the COLOR SENTRY control to the
OFF position and be sure you select a channel that is
telecasting in color.
. Turn the COLOR LEVEL control all the way to the left
to change the color picture to black-and-white.
. Turn the PICTURE control to an approximate mid-range
position.
. Now turn the BLACK LEVEL control to the middle, or
detent, position. This position will usually assure that
areas of the picture which should be black are black.
. Now turn the COLOR LEVEL control to give the picture
as much color as you want.
_ Turn the TINT control for the most natural flesh tones.
. Turn the PICTURE control in either direction to get the
brightness level you want.
. If the dark areas and colors appear faded or washed-
out, the BLACK LEVEL control should be turned to the
left. If light backgrounds and colors appear too dark,
it should be turned to the right.
. We recommend you set the SHARPNESS control in the
mid-range, or detent, position. If you prefer a softer
picture, turn the control to the left. Turn it to the right
for a sharper picture.

AUTOMATIC PICTURE
CONTROL
The Zenith COLOR SENTRY system includes all five of
the following essential picture control circuits working
together to bring you an excellent color picture
automatically, scene to scene, channel to channel.
1. Light Sensor. An “electronic eye” and associated
control circuit automatically adjust picture brightness
for comfortable viewing—in low light, bright light,
any light.
2. Color Signal Monitor. An electronic circuit automatically
checks the incoming color signal and adjusts the
_ picture to prevent over-saturation of color from scene
to scene, channel to channel. :
3. Tint Stabilizer. A special electronic circuit automatically
balances colors to provide lifelike flesh tones.
4. Color Level Lock. Preprogrammed color level and tint
adjustments are locked in to complement the functions
of Color Signal Monitor and Tint Stabilizer.
5. Contrast Regulator. An electronic circuit automatically
maintains preset picture black level. As a result,
dramatic contrast and highlights seen by the camera
are faithfully reproduced.
HELPEUL HINTS.
Never attempt to operate thes set with the back cover
removed.
Never probe or push objects into the set through cabinet
slots.
If the cabinet has been damaged, do not operate the set.
Have it checked by a service technician before use.
-PICTURE-GLASS CLEANING
When you want to clean the face plate of the picture tube,
first turn the set OFF. Wet a soft cloth in lukewarm water
mixed with a little fabric softener or dishwashing detergent.
Wring the cloth almost dry. Wipe the glass. Make sure that
no drops of moisture are squeezed onto the glass. DON’T
wipe the glass dry. Let it air-dry before you turn the set
back on again.
CARE OF CABINET 3
Non-wood cabinets should be cleaned with a mild soap
solution. Use a soft cloth. Rinse with clear water before
wiping dry. Any good furniture cleaner and polish will help
preserve the finish on wood cabinets. Do not place
objects that are made of rubber or plastic on top of the
cabinet unless the cabinet is protected by a cloth doily
or place mat. This is because a chemical reaction may
occur, causing permanent damage to the finish.

INDIVIDUAL CONTROLS
PICTURE
This control lets you adjust the color picture brightness
for varying room light conditions. It does this by adjusting
contrast and color level at the same time and in
proper balance.
BLACK LEVEL
This control lets you adjust the black areas in the
picture to the level you want. Once set, the CONTRAST
REGULATOR, an electronic circuit, automatically
maintains this preset black level from scene to scene,
channel to channel. After the BLACK LEVEL control is
set, further brightness adjustments should be made with
the PICTURE control.
COLOR LEVEL
This control sets the intensity of the colors. If turned too
far to the left, colors appear faded or weak. If turned too
far to the right, colors appear vivid or intense.
TINT
Adjust this control for the most natural flesh tones. If
turned too far to the left, flesh tones will appear purple;
too far to the right, they will appear green.
SHARPNESS
This control lets you get a softer picture by turning the
control to the left. It lets you get sharper picture detail by
turning the control to the right.
AFC (AUTOMATIC FINE-TUNING CONTROL)
The
AFC
“locks”
