 SAFETY INSTRUCTION

  WARNING : Only competent service personnel may carry out work involving the testing or repair of this equipment


   X-RAY RADIATION PRECAUTION
1. Excessive high voltage can produce potentially hazardous X-RAY RADIATION. To avoid such hazards, the high
   voltage must not exceed the specified limit. The nominal value of the high voltage of this receiver is 22-23 kV (14" or
                                                                                                                       )
   24-26 kV (20"- 21" at max beam current. The high voltage must not, under any circumstances, exceed 27.5 kV (14"
                      )                                                                                                  ,
   20" 29KV (21" Each time a receiver requires servicing, the high voltage should be checked. It is important to use an
       ),         ).
   accurate and reliable high voltage meter.

2. The only source of X-RAY Radiation in this TV receiver is the picture tube. For continued X-RAY RADIATION
   protection, the replacement tube must be exactly the same type tube as specified in the parts list.




   SAFETY PRECAUTION
1. Potentials of high voltage are present when this receiver is operating. Operation of the receiver outside the cabinet or
   with the back cover removed involves a shock hazard from the receiver.
   1)Servicing should not be attempted by anyone who is not thoroughly familiar with the precautions necessary when
      working on high voltage equipment.
   2)Discharge the high potential of the picture tube before handling the tube. The picture tube is highly evacuated and if
      broken, glass fragments will be violently expelled.
2. If any Fuse in this TV receiver is blown, replace it with the FUSE specified in the Replacement Parts List.
3. When replacing a high wattage resistor (oxide metal film resistor) in circuit board, keep the resistor body 10 mm away
   from the circuit board.
4. Keep wires away from high voltage or high temperature components.
5. This receiver must operate under AC 230 volts, 5O Hz. NEVER connect to a DC supply of any other voltage or
   frequency.




   PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in this equipment have special safety-related characteristics. These characteristics are
often passed unnoticed by a visual inspection and the X-RAY RADIATION protection afforded by them cannot necessarily be
obtained by using replacement components rated for higher voltage, wattage, etc. Replacement parts which have these spe-
cial safety characteristics are identified in this manual and its supplements, electrical components having such features are
identified by designated symbol on the parts list. Before replacing any of these components, read the parts list in this manual
carefully. The use of substitutes replacement parts which do not have the same safety characteristics as specified in the parts
list may create X-RAY Radiation.

ATSS sorting method

The TV set sweeps all the TV bands from beginning of VHF to the end of UHF. The TV controlling software for each program
checks if a VPS CNI code is transmitted. If no VPS CNI code is found, the system checks if a CNI code is transmitted in the tele-
text lines ( Packet 8/30 format 1 ). If such a code ( VPS or teletext ) is found and if this code is in the ATSS list, the program is
automatically named.
The programs found are then sorted into 4 groups :

Group I : Contains all the programs from the selected country and named by the TV controlling software. Within this group the
sorting order is fixed by the ATSS list.
Group II : Contains all the programs with a strong signal strength which are not listed in group I.
Group III : Contains all the programs with a weak signal strength which are not listed in group I.
Group IV : If two or more programs with the same code are found, only the strongest (or if they have the same level the one
with the lowest frequency) is listed in group I, II or III. The others are listed in group IV.

Note : If two programs with the same name but a different code are found these two programs are listed in group I, II or III (e.g.
Regional program SW3 in Germany).

The sorting order within group II, III, and IV is based on the channel frequency. The program with the lowest frequency is allo-
cated the first rank in its group, and so forth until the last program of the group which has the highest frequency.

Special case : France
If France is selected the TV controlling software firstly sweeps all the TV bands with France system selected (positive video
modulation) and secondly with Europe system selected (negative video modulation).

Special case : Switzerland
If Switzerland is selected the TV controlling software firstly sweeps all the TV bands with Europe system selected (negative
video modulation) and secondly with France system selected (positive video modulation).

Special case : GB
Note for satellite receiver users : Before starting ATSS turn On your satellite receiver and tune "SKY NEWS ".
If GB is selected the TV controlling software seeks for programs only in UHF ( C21 to C70 ). The sorting order is :
1 - BBC1
2 - BBC2
3 - ITV
4 - CH4
5 - CH5
6 - NEWS

If two or more "identical " programs ( same name but different code e.g. BBC1 and BBC1 Scotland ) are found the following pro-
grams in the list will be shifted up. (1 - BBC1, 2 - BBC1, 3 - BBC2, 4 - ITV, 5 - CH4, 6 - CH5, 7 - NEWS, ..)

If one of the program above is not found, the associated program number remains empty ( freq.=467.25 MHz - Skip selected -
