(Text)    weather, stock data or the like, when it is provided by individual station.
 Notes
This projector supports a special feature called closed captioning which allows 
subtitles to be displayed at the bottom of the picture. This is pursuant to the 
Regulations set forth by the US Federal Communications Commission (FCC). Due 
to the different broadcasting or signaling system, it may not operate correctly in 
other regions or countries where TV programs do not support closed captioning.
Closed Caption may not appear correctly depending on the signal conditions or the 
recording conditions of videotapes. 
If the Text is not available, only a black rectangle background may appear on 
screen. 
To prevent this from appearing, set the Closed Caption to [Off].
When you switch channels of broadcasting programs or playing a videotape using 
“trick play” functions such as rewinding or fast-forwarding, those operations in the 
connected device may cause the Caption or Text to remain on the screen for a 
while.
Closed Caption is available for Video and S-Video input images.
