Decoder

Video recorder

If your video recorder is provided with a EURO-AV
socket (”Euroconnector”), you get the best picture
quality if you connect this socket via a EURO-AV
cable (available from your dealer) to the VCR socket
of your receiver.

w

!

No on-screen displays are output via the VCR
socket of the receiver. That is why video recordings
cannot be affected by calling up menus.

When playing back video recordings, the signals
from the video recorder (VCR socket) are looped
through the satellite receiver (also in stand-by) to
the TV set (TV socket) “vcr” will appear on the dis-
play.

Decoder

If you use a decoder which is provided with a
EURO-AV socket (”Euroconnector”), you get the
best picture quality if you connect this socket via a
EURO-AV cable (available from your dealer) to the
DEC socket of your receiver.

After connecting the decoder, please check the
decoder mode selected in the "System setup" menu
3 ("

gramme position concerned ("

How to connect the satellite aerial

w

!

It is absolutely necessary to respect the safety and
installation notes on page 2.

Connect the cable of your satellite aerial(s) to the
INPUT A and/or INPUT B input(s) ( F connector) on
the back of your receiver. The receiver is pre-pro-
grammed. Please see enclosed channel list.

Check to see whether the preset LNC oscillator 
frequency (see pages 14 and 15) corresponds to
the LNC used.

Connection via a EURO-AV cable

TV set

If your TV receiver is provided with a EURO-AV
input (”Euroconnector”), you get the best sound
and picture quality if you connect this socket via a
EURO-AV cable (available from your dealer) with
the TV socket of your receiver.

w

!

Only when using the TV socket of the receiver, the
on-screen displays (menus) will appear when they
are called up.

Second video recorder or decoder

If you wish to connect a second video recorder
instead of the decoder, use the DEC socket for this. 

You can connect a second decoder instead of the
video recorder to the VCR socket, provided the
decoder is suited for the “normal“ decoder mode.
The decoder mode selection (see page 13) is only
possible for the DEC socket.

Terrestrial reception

If you wish to receive also terresrtrial programmes,
connect the terrestrial aerial cable to the AERIAL
socket on the rear of the receiver. The signal for the
video recorder and the TV set is available at the
TV/VCR modulator output of the receiver.

Connection via the modulator
output

If your TV set or video recorder is not provided with
a EURO-AV socket, these sets are supplied via the
TV/VCR socket with the SAT signals. In this case, it
will be necessary to adjust the sets to each other. At
the factory, the modulator of the satellite receiver
has been preset to channel 37.

The following section describes how the TV set and
video recorder are tuned to the receiver.

Tuning the TV set and video
recorder to the receiver

This adjustment can be omitted if you have con-
nected the receiver via a EURO-AV connecting lead
to the television receiver or video recorder.

Press the 

.

key and then the 

1

key on the remote

control unit of the receiver. The receiver then will
send an on-screen display on channel 37.

Select a free channel position on your TV set and
tune to UHF channel 37 (the receiver's output chan-
nel). For this, refer to the instruction book of your TV
set. You will see the following on-screen display.

If this channel is already being used by a TV chan-
nel or a different unit (say, your video recorder),
you will see interference if the other equipment is
operating. 

Retune your TV to an unused part of its range
(channel number 28 to 47).
Turn the adjusting screw "CH. ADJ." on the back of
the receiver by means of a small screwdriver until
you see a picture.

Optimize the picture quality by finetuning your TV
set.

Tune in the same way a free programme position of
the video recorder to the receiver's ouptut channel.

How to connect your hifi system

Best sound quality is obtained when connecting the
receiver to hifi equipment. 
On the AUDIO OUT L and R sockets only the sound
of the selected TV or radio programme of the tuner
A is provided.

Connect the AUDIO OUT L (left) and R (right)
sockets on the back of your receiver via a phono
(Cinch) cable (available from your dealer) to the hifi
amplifier.
