Closed Captions  
Closed captioning is a process which converts the audio portion of a television program into written words which then appear as sub-  
titles on the television screen. Closed captions allow viewers to read the dialogue and narration of television programs.  
Using Closed Captions  
Captions are the subtitles of the dialogue and narration of television programs. For prerecorded  
programs, program dialogue can be arranged into captions in advance. Its possible to caption a  
live program by using a process called real-time captioning, which creates captions instantly.  
Real-time captioning is normally done by professional reporters using a machine shorthand sys-  
tem and computer for translation into English.  
Captioning is an effective system for the hearing-impaired, and it can also aid in teaching lan-  
guage skills.  
FOLLOW ME  
The picture at left shows a typical caption.  
Caption Tips  
Not all TV broadcasts include closed caption signals.  
Sometimes TV stations broadcast four different caption signals on the same channel. By selecting From CC 1 to CC 4, you can  
choose which signal you view. CC 1 is usually the signal with the captions, while Another mode might show demonstration or  
programming information.  
Your TV might not receive caption signals normally in the following situations.  
1. Poor reception conditions are encountered:  
IGNITION:  
Picture may flutter, drift, suffer from black spots, or horizontal streaking. Usually caused by inter-  
ference from automobile ignition systems, neon lamps, electrical drills, and other electrical appli-  
ances.  
GHOSTS:  
Ghosts are caused when the TV signal splits and follows two paths. One is the direct path and the  
other is reflected off tall buildings, hills or other objects. Changing the direction or position of the  
antenna may improve reception.  
SNOW:  
If your receiver is located at the weak, fringe area of a TV signal, your picture may be marred by  
small dots. It may be necessary to install a special antenna to improve the picture.  
2. An old, bad, or illegally recorded tape is being played.  
3. Strong, random signals from a car or airplane interfere with the TV signal.  
4. The signal from the antenna is weak.  
5. The program wasnt captioned when it was produced, transmitted, or taped.

Maintenance & Product Specifications  
Maintenance  
- Early malfunctions can be prevented. Careful and regular cleaning can extend the amount of time you will have your  
new TV. Be sure to turn the power off and unplug the power cord before you begin any cleaning.  
Cleaning the Screen  
1. Heres a great way to keep the dust off your screen for a while. Wet a soft cloth in a mixture of lukewarm water and  
a little fabric softener or dish washing detergent. Wring the cloth until its almost dry, and then use it to wipe the  
screen.  
2. Make sure the excess water is off the screen, and then let it air-dry before you turn on your TV.  
Cleaning the Cabinet  
To remove dirt or dust, wipe the cabinet with a soft, dry, lint-free cloth.  
Please be sure not to use a wet cloth.  
Extended Absence  
If you leave your TV dormant for a long time (such as a vacation), its a good idea to unplug the power  
cord to protect against possible damage from lightning or power surges.
