Digital NICAM Behaviour
If the signal received does not indicate a valid and error free
NICAM sound, then analog FM/AM sound is selected.
Otherwise NICAM is selected automatically. After each
programme change, the NICAM sound will be preferred.
NICAM sound preference will be respected if the received
sound type indicates that the NICAM sound is related to the
picture. Otherwise NICAM preference will be overruled by
switching to analog FM or AM mono. Whenever the user forces
a different sound mode, the automatic following of the received
sound type will be terminated and forced preference of the user
is assigned the higher priority. The bit error rate is monitored
regularly to check the quality of the NICAM signal. The analog
FM/AM mono channel is forced when the bit error rate exceeds
a maximum value. The previous sound mode will be restored
as soon as the bit error rate drops below the maximum value.
If the previous sound mode happens to be analog FM or AM,
then this will have no effect.

Volume:
Volume can be controlled within local keyboard or by the
remote control unit. If mute is active and volume up key is
pressed, audio will exit mute and volume will start to increase
from the indication mark where it was muted previously. If mute
is active and volume down key is pressed, audio will stay in
mute and start to decrease from the indication mark where it
was muted previously. When mute is deactivated audio value
will preserve its last setting.
Mute:
LS sound can be switched off temporarily with the MUTE key.
Sound can be switched on again by;
•
Re-pressing the mute key.
•
Pressing the V+ key.
•
While mute is active and the volume down key is pressed,
preserving the mute condition audio will start to decrease
from where it was muted previously. When mute is
deactivated audio value will keep it's last setting.

Mute will be stored to NVM before cold power on and will stay
in it's last state after switching the TV set on. All through the
time mute is active, mute symbol will be displayed on the
screen permanently.
Back-end Mute:
The loudspeakers and the headphone are automatically muted
when there is no ident from the video processor. Audio is muted
within 200msec after the back-end ident disappears. Mute
stays active for 1sec. after ident returns. For all internal and
external sources that are selected, this ident control and sound
mute will be performed.
Front-end Mute:
If the terrestrial front-end does not deliver any ident, audio is
muted within 200 msec. after the front-end ident disappears.
Mute stays active for 1 sec. after the ident returns.
Smart Sound Modes
4 different Smart Sound Modes (Voice, Music, Theatre and
Personal) are available. User can select any of these modes or
return to the personal selections. Using the Smart Sound key
on the Remote Control unit can perform selection of different
modes or returning to personal selections. When Smart Sound
key is pressed for the first time, an OSD stating the current
mode will be displayed. In order to select another mode this key
must be pressed before the OSD disappears (within 5
seconds). The last selected mode is always stored to NVM.

Pin8 Behaviour for EXT:
•
While the set is going out of Standby (if the last state of the
set is not Standby State before cold power off, set will go
out of Standby automatically after cold power on), if the
Scart Pin8 is activated set will automatically switch to
external source.
•
While the set is in RF mode (if not any menu displaying and
if teletext is not activated), if Pin8 is activated (including
Canal +) set will automatically switch to external source.
•
If set switches to external source with Pin8, P+/P- keys on
the RC or keyboard will react as if set is in the last program
or source before switching to external source not in
external mode.
ie:
–
Set is in Program 5 Press P+ - Set is in Program 6
–
Pin8 activated while set is in Program6 - Set switches to
EXT
–
Press P+(or P-) - Set will switch to Program7 (or Program5)
