* The character sets are shown correctly for the indicated languages only if the teletext
decoder of the TV offers the West European languages. If the TV has a
different decoder, for example, Eastern Europe, the characters generated by 54200
are shown in the corresponding language. The different languages are controlled by
the Page Header Control Bits (C12 to C14) of the teletext data. For example, the
generated character set of Page 200 is shown by a decoder for Western Europe in
British and will be shown in Polish with a decoder for Eastern Europe.
** PDC/VPT test data are only programmable if the instrument has the PDC/VPS
option.
