Fasttext Operation
In addition to the standard Teletext functions, the receiver GT 2105
has Fasttext. This system provides more value from Teletext by
allowing fast access to highlighted pages and by linking many related
pages for easy access.
The key to Fasttext is four colour coded prompts at the bottom of each
teletext page. These red, green, yellow and blue prompts relate to the
four colour coded buttons on the tv remote control.
Each colour coded prompt acts as a "signpost" through the huge
choice of Teletext pages available, allowing faster and easier access
to highlighted pages.
Use of Fasttext
To select any colour coded page from Teletext press the correspond-
ing coloured button on the TV remote control.
The new page selected will appear almost instantly although there can
still be a delay for some pages to appear. This is particularly the case
if a rapid succession of coloured Fasttext buttons are pressed.
As new pages are accessed, at the bottom of the page a new series of
subject related colour coded prompts will appear.
Fasttext Index Function
To return any time to the main index pages it is not necessary to enter
the index page number.
INDEX To return to the main index press the INDEX button once.
INDEX With the main index on screen a further press of the INDEX
button will access the main A - Z index or other subsidiary index
pages.
