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 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 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.
