8.3.1 Options
Options are used to control the presence/absence of certain
features and hardware.
How to change an Option Byte
An Option Byte represents a number of different options.
Changing these bytes directly, makes it possible to set all
options very fast. All options are controlled via seven option
bytes. Select the option byte (OP1.. OP7) with the MENU UP/
DOWN keys, and enter the new value.
Leaving the OPTION submenu saves the changes in the
Option Byte settings. Some changes will only take effect after
the set has been switched “off” and “on” with the AC power
switch (cold start).
How to calculate the value of an Option Byte
• Calculate an Option Byte value (OP1 .. OP7) in the
following way:
• Check the status of the single option bits (OB): are they
enabled (1) or disabled (0).
• When an option bit is enabled (1) it represents a certain
value (see column “Bit value” in table below). When an
option bit is disabled, its value is 0.
• The total value of an Option Byte (decimal) is formed by the
sum of its eight option bits. The factory values are printed
on a sticker on the CRT (depends on region).
