The MODE Menu
SKEW ALL – Transferring the Skew Value
After having adjusted the optimum value for a polarization
plane, e.g., horizontal, in the "SKEW" menu option (polarizer
adjustment),
press the
¢
MODE
ɶɶ
button once again.
The display indicates "
SKEW ALL
".
Store with the
¢
MEMORY button.
The optimum skew value set before is automatically transfer-
red into all horizontally preprogrammed programme positi-
ons of the same group (H1 or H2).
Next, select a station with vertical polarization, optimize the
skew value in the "SKEW" menu option, call up the menu op-
tion "SKEW ALL" with the
¢
MODE
ɶɶ
button, and press the
¢
MEMORY button to store in memory. All vertically prepro-
grammed stations of the same group (V1 or V2) are automa-
tically optimized.
WIDE/NARROW – IF Bandwidth
The display indicates "
WIDE
" or "
NARROW
".
If the aerial signals are very weak, or to suppress possible
interference signals, it is recommended to switch the IF
bandwidth to "
NARROW
" by pressing the
¢
<
/
>
buttons.
This will improve the picture quality.
Then, press the
¢
P/F button once again, use the
¢
<
/
>
buttons to correct the frequency in single steps to get a mini-
mum number of spikes, and store with the
¢
MEMORY but-
ton.
DECODER
"
DECODER
" is indicated in the display.
It is possible to switch the decoder into the signal path and to
select between "
AUTOMAT.
" and "
ON
" by means of the
¢
<
/
>
buttons.
Select "
AUTOMAT.
" for decoders which deliver a switching
voltage when a decoded (scrambled) programme is received,
for example, Premiere.
Select "
ON
" for decoders which do not evaluate the switching
voltage.
The receiver is preset to "
AUTOMAT.
".
VID & AUD – Decoder Selection
With the
¢
<
/
>
buttons, it is possible to select whether pic-
ture and sound signals (indication. "
VID&AUD
") or only
video signals (indication: "
VID ONLY
") are to be passed
through the decoder for decoding ("descrambling").
NORM – Norm 1, 2 or 3
In this menu option, you can select the norm in which the
signals are to be available at the decoder socket.
With the
¢
<
/
>
buttons, it is possible to switch the signal at
pin 19 of the decoder socket between
NORM 1 = clamped video signal (e.g., 2nd VCR, Première),
NORM 2 = baseband with PAL deemphasis (e.g., Video
Crypt), and
NORM 3 = baseband with linear deemphasis (e.g., MAC).
The selected norm (1, 2 or 3) is indicated in the display.
DEEMPH. – with MONO < >
This menu option is only called up if you have selected the
sound mode "Main carrier Mono < >" in audio mode. If so,
you can switch the audio deemphasis between J17 and
50µsec by means of the
¢
<
/
>
buttons. This selects the
signal filter characteristic for the sound signal.
For "MONO > <" and "STEREO", this menu option is not requi-
red and therefore skipped.
