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.
