8.4.4 OPT. NO. (Option numbers)
Select this sub menu to set all options at once (expressed in
two long strings of numbers).
An option number (or option byte) represents a number of
different options. When you change these numbers directly,
you can set all options very fast. All options are controlled via
eight option numbers.
When the EAROM is replaced, all options will require a re-
setting. To be certain that the factory settings are reproduced
exactly, you must set both option number lines. You can find
the correct option numbers on a CRT sticker inside the TV set.
Example: The CRT sticker in the 28PW9502/12 gives the
following option numbers (Note: this is just an example):
12660 16672 49984 00000
04118 00001 00032 18250
The first line (group 1) indicates options 1 to 4, the second line
(group 2) options 5 to 8 (see tables below).
Every 5-digit number represents 16 bits (so maximum number
can be 65536 if all options are set).
When all the correct options are set, the sum of the decimal
values of each Option Byte (OB) will give the option number.
