Necessary conditions for the TV GUIDE to operate correctly
The Sharp TV GUIDE works by copying information from the Teletext service for each of the four channels. 
For the TV to perform this function properly:
1. Teletext must be available on all 4 channels.
The Teletext for these channels must include pages with hourly schedules of the day's broadcasts.
3. The channels must be set to Pr 1, Pr 2, Pr 3 and Pr 4 on the TV.
4. The TV's real time must be set properly.
5. The TV's configuration must be correct (channel names and teletext paths).
Note: The TV's configuration must be changed only if the channels change the teletext pages where hourly
programming schedules are located.
If the TV cannot copy the data properly from the Teletext, the words "NOT AVAILABLE" appear on menus A and B.
If this happens, display menu C to see the teletext page containing all programming.
To facilitate the teletext scanning process, the automatic data search is also performed periodically while the TV is 
in Stand-By mode.
•  If the TV is turned off with main switch (
®) the data will be lost.
•  If the TV is turned off with the (
æ TV) button on the remote control, then if TV is switched on less than 30 
seconds later data will be lost, other wise, data will not be lost.
•  If data is lost, the search will be repeat once the TV is turned back on.
Menu C
C.- Teletext page with all programming.
A cursor appears too.
Normally, those broadcasting stations with teletext send at least their own programming on several pages of text; in
some cases, information on the programming of other stations is also available. 
Your television is able to scan these pages and extract the information needed to tell you what program is presently on
the screen, what program will follow, or the side page of the programming TXT of the station that you are watching. 
The above operations require the following:
The system must be configured properly (see the relevant section). 
The station that you are currently watching must be sending teletext data containing pages with information on the
programming of the stations stored in the programs PR 1, PR 2, PR 3 and PR 4. 
To understand the operation of this system, the following points must be taken into account:
The information can only be captured starting from the station that is presently on the screen. That is why you must
view certain stations for several minutes before the data is available. Those stations that provide information only about
their own programming must be on the screen for a few moments before the data appears otherwise, you will be advised
that the data are not available.
On the other hand, when you are viewing stations whose teletext contains information about several stations, after a
few minutes you will find further information. 
The information written on the screen consists, in reality, of fragments of the lines that appear in the teletext pages.
Therefore, it is normal to find occasional errors and spurious characters. 
During the time the information is being captured (a few minutes, since generally several different teletext pages
must be captured), the data that you see written on the screen are not reliable. This is natural since the system can only
function properly after all the pages of data have been captured. 
Select a program from
Pr 1 to Pr 4 and press
button two or 
three times until the 
menu is displayed
Note: If the time shown in the upper right-hand corner of this menu is not correct, reset it to the correct time (see the
Connection section of Special Functions). 
In the case shown in the example, the error is due to the fact that the information captured corresponds to the last time
slot of the day (21.00 to 23.55h). The correct data will appear after a brief time interval, when the missing information is
received through the teletext. 
Examples of operation:
Let’s assume you have stored the stations shown below in PR 1 through PR 4: 
PR 1 .......... BBC1
PR 3 .......... ITV
PR 2 .......... BBC2
PR 4 .......... CH4
At the present time BBC1 and BBC2 transmit in their teletext pages the programming schedule of both BBC1, BBC2
and ITV. This means that whether we have selected PR 1 (BBC1) or PR 2 (BBC2), the television is able to capture
information on BBC1, BBC2 and ITV. 
To obtain information on CH4, we must necessarily spend several minutes in PR 4, since none of the stations that we
have stored in the TV memory supplies information on that station. 
Once the information has been captured, it remains in the memory and will not be lost until we turn off the TV or we
enter the tuning menu. 
Help Line (office hours only): 08705 274277
Your television already has a basic configuration stored in memory that should meet any of your essential needs in the 
immediate future. However, the configuration must be revised every time that:
An automatic search is conducted. 
Some change has been made in the way the information is transmitted or in the page numbers that contain the
information on each of the stations. 
A new station is added. 
Before we explain how to configure the system, several points about the teletext are worth clarifying: 
Some broadcasting stations send teletext data and some do not. You can find out whether teletext is available
by pressing the TEXT/MIX button. If you see a black screen, there is no teletext. 
The information that you receive in the TXT is presented in pages, each of which is associated with a number
that appears in the upper left-hand corner.
There are two kinds of pages that are of interest for correctly configuring the TV Guide:
Rolling: pages which once they are requested, regularly change their content (about once every minute).
Usually these are identified by the appearance on-screen of one of the following character groups on  one of the pages:
1/3 or 2/3 or 3/3 or 2/5 or 3/5 or 4/5...
In the above cases, the characters indicate that the page being displayed is the first, second or third page of a total set
of 3, or the second, third or fourth page of a total set of five. 
Non-rolling: pages whose content does not change. 
If the station is transmitting teletext using the FLOF standard, a coloured line appears in the lower area of the text. 
Pressing a colour key accesses new pages associated with these colours. (The allocation of page number to colour is
done by the broadcasting station, and the television automatically decodes it). 
1. Items of Information and path
Press the MENU button, press BLUE button and press YELLOW button to see the TV GUIDE menu.
The name of a station will appear (on a white ground) with data to the right (on a red ground). 
The meaning of this data is clarified by this example:
The first line describes the information that can be found on the station identified as XXX1. The two items (401 and 
indicate the access path to the information and the third item (Rolling) indicates the type of page; finally, the last element
indicates that the information for the end user concerns the station XXX1. 
The second line shows very similar data, indicating the access path and the type of page where the end-user information
on station XXX2 is found. 
These data instruct the television how to proceed when the station XXX1 is being viewed (normal operation of the set).
In this particular case the TV will automatically request page 401 of the teletext and then the page associated with the
colours green and red (to access the programming information on XXX1 and XXX2). 
Two important points should be stressed:
The information captured by the TV can only be effectively displayed if (in the example presented above) XXX1 and
XXX2 are stored in the memory of PR 1 to PR 4. 
The entire process described above is automatic once the system has been configured correctly. There is 
nothing further that must be done. 
Using the buttons 
(up and down), you can move through all the elements on the list, noting that for
each station identification there are different page numbers and different access modes. For example: 
All these data instruct the TV that, when XXX1 is being viewed, the search for the XXX1 programming information should
begin on page 301 (301 and 
), and that this information is not in rolling format; that is, it will request the consecutive
pages from 301 on, up to a maximum of six pages. The procedure is identical for accessing information about XXX2.
