CAUTION concerning the Power Cord
Most appliances recommend they be placed upon a dedicated circuit; that is, a single outlet circuit
which powers only that appliance and has no additional outlets or branch circuits. Check the specification page of this owner's manual to be certain.
Do not overload wall outlets. Overloaded wall outlets, loose or damaged wall outlets, extension
cords, frayed power cords, or damaged or cracked wire insulation are dangerous. Any of these conditions could result in electric shock or fire. Periodically examine the cord of your appliance, and if
its appearance indicates damage or deterioration, unplug it, discontinue use of the appliance, and
have the cord replaced with an exact replacement part by an authorized servicer.
Protect the power cord from physical or mechanical abuse, such as being twisted, kinked, pinched,
closed in a door, or walked upon. Pay particular attention to plugs, wall outlets, and the point where
the cord exits the appliance.

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 wasn’t captioned when it was produced, transmitted, or taped.
Closed captioning is a process which converts the audio portion of a television program into written words
which then appear as subtitles on the television screen. Closed captions allow viewers to read the dialogue and narration of television programs.
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 system
and computer for translation into English.
Captioning is an effective system for the hearing-impaired, and it can also aid
in teaching language skills.
• The picture at left shows a typical caption.
• IGNITION:
Picture may flutter, drift, suffer from black spots, or horizontal streaking.
Usually caused by interference from automobile ignition systems, neon lamps,
electrical drills, and other electrical appliances.
• 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.

Another mode might show demonstration or programming information.
• Your TV might not receive caption signals normally in the following situations.

1. Here’s 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 it’s
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.
To remove dirt or dust, wipe the cabinet with a soft, dry, lint-free cloth.
Please be sure not to use a wet cloth.
If you leave your TV dormant for a long time (such as a vacation), it’s a good idea to
unplug the power cord to protect against possible damage from lightning or power surges.
- 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.
