Options
Options OP1...OP7 in the SAM menu can be used for quickly
restoring 64 features or settings of the HERCULES 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 HERCULES 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 HERCULES 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 NVM
Editor in the SAM menu. In the 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
HERCULES 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 HERCULES options. Changing these
bytes directly makes it possible to set all HERCULES 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
HERCULES 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. A second range of settings and features
can be found in Chapter 5 of this manual, in table
NVM Default
values
. The settings mentioned there can only be changed via
the NVM editor. For further settings, see also the table “ADC
Gain and Grey scale alignment” elsewhere in this manual.
