Teletext is an information service transmitted by most TV stations. The index page of the teletext service
(usually page 100) gives you information on how to use the service. To operate teletext, use the remote
control buttons as indicated below.
Teletext errors may occur if you use a channel (TV Broadcast) with a weak signal.

Input the 3 digits of the page number, using the numbered buttons.
• If you have made a mistake, retype the correct page number.
• If the counter on the screen continues searching, it is because the page is not
available. 
In that case, input another page number.
To access the next or preceding page:
Press PROG +  (
