What is Teletext?
Teletext is an information service, organized like a magazine, which is
provided by some television stations in addition to regular television
broadcasting. Your television receives special Teletext signals
broadcast by a TV station, processes the information and displays it
graphically on the screen. News, weather and sports information,
stock exchange prices, program previews and closed captioning for
the deaf are among the many services available through Teletext.
Teletext information is organized much like a magazine: according to
pages and sub-pages. The basic unit of displayed information is the
page. A sub-page is one of a series of pages.
Teletext reception is controlled by using the remote control. Refer to
the appropriate button descriptions for operation of the Teletext
functions. 
Teletext features
Depending on the TV programme, the Teletext pages are transmitted
using different systems. Your SHARP TV is adjusted to receive 2
Teletext systems, namely FLOF and LIST, which are automatically
identified by the receiver.
The user can easily identify them by the manner in which they appear
on the screen.
