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 (OB1.. OB7) with the MENU UP/
DOWN keys, and enter the new value.
Leaving the OPTION submenu and switching the set off with
the standby button on the remote 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 (OB1 .. OB7) in the following
way:
1. Check the status of the single option bits (OP): are they
enabled (1) or disabled (0).
2. When an option bit is enabled (1) it represents a certain
value (see first column 'value between brackets' in first
table below). When an option bit is disabled, its value is 0.
3. The total value of an Option Byte is formed by the sum of
its eight option bits. See second table below for the correct
Option Bytes per typenumber.
