GRUNDIG accessories for satellite reception systems
Your dealer or technician will be pleased to give you details on GRUNDIG's comprehensive range of
accessories for satellite receiver equipment.
To operate the receiver you will need a suitable satellite aerial, installed and aligned to the required
satellite (eg ASTRA).
The installation and connection of this satellite aerial is a complex task and is best left to a professional.

SPECIAL FEATURES _____________________________________________________________

One satellite receiver with two reception units
Dear Customer,
To use the receiver you will need a suitable satellite aerial which must be installed and aligned with
the desired satellite (for example Astra).
The satellite receiver STR 7122 TWIN is fitted with two separate reception units Aand B
(Input Aand Input B).
Both reception units (Aand B) of the satellite receiver must receive the signals from the same
satellite.
Reception unit A(Input A) is provided for TV operation, reception unit B(Input B) for video
operation.
By means of this comprehensive equipment, you may
– Input A: watch one satellite programme on a TV set and
– Input B: record at the same time a second satellite programme on your video recorder,
or
– watch two different satellite programmes on two TV sets.
So that it will be easier for you to make a selection and enter the necessary settings, we have pre-
programmed most of the channel positions available via this satellite receiver using all the settings
required.
The pre-set satellite channel positions available via this receiver are shown separately on the enclosed
table of stations.
This table does not claim to be either complete or fully up-to-date.
Current satellite data can be called up using the Teletext tables of the various satellite channels
(eg SAT 1 or 3SAT Text), or via Internet, and will also be available in any current satellite TV guide.

SPECIAL FEATURES ___________________________________________________

You will, of course, be able to re-programme "new" satellite channels in an easy and straight-
forward way.
The television's on-screen menus provide the dialogue between the user and the receiver.
The receiver will respond to many of the functions selected via the remote control by displaying info
menus and on-screen symbols on the TV screen.
In a simple and understandable way, you will be guided step-by-step to the next setting available.
We have also provided you with a symbol card, which sets out all the symbols used in the menu and
gives an explanation of each one.
Using the sub-menus you can
programme the timer;
lock the satellite receiver;
select and mark your favourite programmes;
change channel position settings, e.g. the transmission frequency,
set the LNC polarity, change sound settings;
choose decoder settings, change the contrast settings;
select and change the basic settings;
make LNC settings;
switch the LNC voltage on/off.

INSTALLATION AND SAFETY______________________________________________
In order that you may enjoy this high-quality and comfortable satellite receiver for a long time it
is very important that you observe the following points when installing the receiver.
This satellite receiver is intended for the reception of TV picture and sound signals.
Any other application is expressly prohibited.
If the receiver is exposed to drastic temperature changes, for example when taking it from a cold
to a warm place, connect it to the mains supply and let it stand at the new place for at least
two hours.
Do not expose the satellite receiver to any moisture.
The receiver is intended for use in dry rooms. If you wish to operate it in the open air, make
absolutely sure that it is protected against moisture (rain, splashes of water).
Do not place any object filled with water (vases and similar) on the receiver.
The object might fall over and the liquid spilling into the unit would impair its electrical safety.
Place the receiver on a flat and hard surface. Do not place any objects (e.g. newspapers) on
the receiver.
If placed on a wall-mounted unit, the all-round distance between the receiver and the sides of
the wall unit must be at least 10 cm!
Do not place the receiver in the immediate vicinity of a heat source or in direct sunlight as this would
prevent appropriate cooling.

INSTALLATION, SAFETY, ENVIRONMENT ______________________________________
Thunderstorms are a danger for any electrical appliance. Even when switched off, the receiver might
be damaged by lightning striking the mains supply and/or the aerial lead. During a thunderstorm
you must always disconnect the mains and aerial plugs.
Never open the receiver. Damage caused by unqualified work is not covered by the manufacturer’s
guarantee.
For this satellite receiver, technology and ecology form a convincing overall idea. Only ecologically
high-grade materials are used. The packing consist of almost 100% recycled paper, its plastic parts
have been reduced to a minimum.
The batteries supplied are free of mercury and cadmium. For environmental reasons no buffer
battery is used.
To enable a high-grade recycling after use, the number of plastic parts has consequently been reduced.
All large plastic parts are marked.
To facilitate service and for optimum recycling, this receiver has been designed in a specially
disassembly-friendly and recycling-friendly way.
Do not dispose of used batteries, also those free of heavy metals, together with domestic waste.
Please dispose of them at the appropriate collection points.
If you are not using the receiver for a lengthy period (including overnight), please switch it over to
standby. This saves energy.
This manual is printed on recycled paper. This helps to protect the environment.

PRE-PROGRAMMING_________________________________________________________
Explanatory notes about the table of stations
The extra station table attached provides an overview of the pre-programmed channels on each
satellite.
In the station table, the channels of each satellite are grouped together and marked with a number
(e.g. 1Astra, 2Eutelsat etc.).
Example:
So that the Eutelsat 13°/Hotbird satellite can be received together with the Astra or Eutelsat 16°
satellite, their channel positions are pre-programmed several times.
When receiving from more than one satellite, the pre-programming facility supports aerial
systems with either a digital DiSEqC signal (DiSEqC 1.0), a ToneBurst switch (settings A/B) or
a 22 kHz switch (settings – 0 kHz/~22 kHz).
The table below shows several examples of use:
Which channel position groups can be used for the reception of which satellite (using the appropriate
aerial? How many further combinations are possible.)
*LNC for the 11 GHz range.
** LNC for the 11 and 12 GHz range. When using a Universal LNC, the LO frequencies must be corrected in the “LNC set-up”
sub-menu, see section “LNC oscillator frequencies”, page 38.
