Options
Options OP1...OP7 in the SAM menu can be used for quickly
restoring 64 features or settings of the SCALER part of the TV
set to their orginal default factory values (8 groups of 8
features/settings each). When the decimal value of one option
byte OP1...OP7 is changed (see the first table below) then a
group of 8 bits, representing 8 SCALER options or features, is
changed as well (see the second table below for a detailed
description of the features or settings that are changed).
The second table shows which option byte (OP1...OP7)
represents which group of 8 option bits. Each bit (0...7)
switches a particular SCALER feature or setting ON or OFF,
depending on its value (1 or 0).
It is also possible to change the features or settings mentioned
in the second table directly at bit level, by means of the SC (i.e.,
SCALER) NVM Editor in the SAM menu. In the SC NVM Editor,
first the correct NVM address (ADR) has to be entered, then the
correct value (VAL, 1 or 0) for each bit (see second table), and
finally the settings have to be stored (STORE). For quickly
restoring the SCALER part of the TV set to its original factory
settings, however, it is more convenient to simply enter the
default factory settings OP1...OP7 that are given in the first
table below. How to do this, is described in the next paragraph.
How to Change an Option Byte
As has been explained above, an Option byte (OP) represents
a number of different SCALER options. Changing these bytes
directly makes it possible to set all SCALER 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 (decimal) value. For the correct Factory Default
settings, see the first table below. For more detailed
information, see the second table.
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 Change Options at Bit Level
If you wish to know which features or settings of the SCALER
are changed via OP1...OP7, or if you want to change each
option or feature bit by bit, use the more detailed table below.
Note: the table below contains only part of the NVM settings
that can be changed (i.e., only part of the SCALER settings). A
second range of settings and features, belonging to the
HERCULES part of the TV set, can be found in Chapter 5 of
this manual, in Table 5-2. The HERCULES NVM settings
mentioned there can only be changed via the NVM editor, and
