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 cursor UP/
DOWN keys, and enter the new value.
Leaving the OPTION sub menu 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).
