8.3.1 Options
Options are used to control the presence or 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 quickly. All options are controlled via seven option
bytes.
Note: Each option byte controls several features of the
television set; therefore, before changing option byte
information, it is important to record the current option byte
values. This ensures that the television features can be
restored to the original settings, if necessary.
1.
To enter SDAM, press the following key sequence on the
remote control transmitter: 0 6 2 5 9 6 directly followed by
the MENU button (do not allow the display to time out
between entries while keying the sequence).
2. Use the MENU UP/DOWN keys to highlight the OPTIONS
sub menu.
3. Press the MENU LEFT or MENU RIGHT key to enter the
OPTIONS sub menu.
4. In the OPTIONS sub menu, press the MENU UP/DOWN
keys to select 'OP 1' through 'OP 7'.
5. Use the number keys on the remote control transmitter to
enter a new value for the selected option byte. The value
must be entered as a three-digit value (for example, '4'
would be entered as '0 0 4').
6. The selected value must be between '0' and '255'.
7. When all desired changes to the option bytes are made,
press the MENU button to return to the top level SDAM
menu. This will save changes to the option byte settings.
8. To ensure the option byte changes take effect: Turn the
television set OFF by using the POWER button on the
remote control transmitter or the local keyboard.
Disconnect the television set from AC power for at least ten
seconds. Reconnect the television set to AC power. Turn
the television set ON by using the POWER button on the
remote control transmitter or the local keyboard.
