INTRODUCTION
WELCOME
Welcome into the family of Zenith Color Television owners.
This guide provides instructions on how to operate your new
TV. In addition, we strongly advise you to read and observe
the precautions listed in the Safety Tips section of this operat-
ing guide. Read this publication carefully so that you will re-
ceive full enjoyment from your new Zenith TV for many years
tO come.
Your new TV has been designed and built to give you the very
best in quality, features and performance. There are many re-
gional Zenith authorized service centers throughout the U.S.,
Canada and Mexico who can attend promptly and effectively
to ordinary service needs.
If you should have an unusual performance or service problem
that cannot be saaisfactorily resolved by your Zenith authorized
service centeL call or write:
Zenith Electronic2: Corporation
Customer Service Department
1000 Milwaukee Avenue
Glenview, IL 60025-2493
Telephone: (847)391-8752
Mon-FrL 8:00 a.m. - 4:30 p.m. Central Time
Send the model number, serial number, and date of purchase
or original installation, with a full explanation of the problem
and the service lnistory. We will ,welcome the opportunity to
look into your specific question or problem and to be of assis-
tance in resolving it promptly.
The model and serial numbers of your new TV are located on the
back of the TV cabinet. For your future convenience and protec-
tion, we suggest that you record these numbers here:
Model No.
SeriaI No.
INSTALLATION CONSIDERATIONS
Before you install your TV...
Ventilation -- Proper ventilation keeps your TV
running cool. Air circulates through perforations
in the back and bottom of the cabinet. Do not
block these vents or you will shorten the life of
your TV.
_k Power Source -- Your TV is designed to operate
on normal household current, 120 volt 60 Hertz AC.
1)o not attempt to operate it on DC current.
Power Cord -- Your power cord has a polarized
plug as required by Underwriters' Laboratories. It
!_as one regular blade and one wide blade and fits
only one way into a standard electrical outlet. If
the blades will not enter either way, your outlet is
very old and non-standard. A new outlet should be
installed by a qualified electrician.
Sate Operation -- Your TV is manufactured and
tested with your safety in mind. However, unusual
stress caused by dropping or mishandling, expo-
sure to flood, fire, rain or moisture, or accidental
spilling of liquids into the TV, can result in poten-
tial electrical shock or fire hazards. If this hap-
pens, have your TV checked by a service
technician before using it again.
Please read and observe each safety point in the "Safety
Tips" section when installing and using your TV.
VIDEO GAMES AND OTHER FIXED
PATTERN DISPLAY CAUTION -- If you use your TV for
video games or if you watch channels that continuously show
a logo or other fixed display, avcid setting the BRIGHTNESS
control for an excessively bright picture. A fixed display is
any image which does not change frequently, such as a chan-
nel network/identification or other symbol that remains in the
same location for long periods of time. A bright, fixed pattern,
if left on for long periods of time, can result in a permanent ina-
print on the TV picture tube. You can reduce thiis possibility
by alternating the use of the fixed pattern display with normal
TV picture viewing, by turning down the CONTRAST control
for sustained fixed pattern use, and by turning off the fixed pat-
tern display when not in use.
PLUGGING IN YOUR TV --- Be sure to plug your TV into
an "unswitched" AC power source. The "switched" AC out-
lets found on some video equipment will not continue supply-
ing power to the TV once the equipment is turned off. If the
power to the TV is interrupted, you will have to reset the clock
in the TV to the current time.

MAINTENANCE AND TROUBLESHOOTING
CARING FOR YOUR "IV
Your TV will look better, have a longer life and perform better
if you care tot it properly.
First check to see that the TV is off. For added
_k safety, unplug the TV from the power outlet.
NOTE: If you unplug your TV, you will have to
reset the clock to the current time.
Cabinet Care

cloth with a mild soap solution or Ivory dishwashing deter-
gent. Wipe the surface with a damp cloth. Then rinse the cloth
in clean water and wipe the surface again. Allow the "IV to air-
dry before turning it on.
Wood Cabinets or Cabinet Components Use any good fur-
niture cleaner and polish. Regular care will help preserve the
finish.
Picture Glass Cleaning
The picture tube face attracts dust particles and should be
cleaned regularly. To clean the 5ace, spray a small amount of
glass cleaner on a cleaning cloth and wipe the picture tube
glass face until clean. Repeat if necessary.
To delay new dust accumulation, wet a soft cloth in lukewarm
water in which a little fabric sol!tener or Ivory dishwashing de-
tergent has been mixed. Wring the cloth almost dry. Wipe the
glass face. Make sure no drops of moisture are:squeezed onto
the glass. Do not wipe the glass dry. Allow the glass to air-dry
before you turn the 'IV on agai a.
EXTENDED ABSENCE
Before an extended absence (such as a vacation) you may
want to unplug the power cord from the electrical wall outlet.
This will protect the TV from possible damage from lightning
or power line surges. If you have an outdoor antenna, you may
also want to disconnect the antenna lead-in wires on the back
of the TV,
NOTE: If you unplug your TV, you will have to reset the
clock to the current time.
TV PICTURE INTERFERENCE
Your TV picture may be affected by interference caused by
one or a nmnber of factors. These include:
Speckled or Streaked Picture Can be caused by nearby auto-
mobile ignition, electrical appliances, etc. This is most notice-
able in weak signal areas.
Snow in Picture Caused by insufficient signal. Usually
caused by the TV being located too far from the TV station or
by an improper antenna installation.
Ghosts or Reflections Caused by signals being reflected
from surrounding building:s, water tanks, or other high struc-
tures.
Radio Signal Police, amateur or CB radio transmitters may
cause interference.
These interference probleras can often be corrected through
the use of a better antenna, signal amplifiers;, or various filter
devices. See your TV dealer for additional information, and
available TV accessories.
