LNC arrangements ($)
1
In order to tune the receiver as finely as possible to
the various aerial installations, 6 LNC arrangements
are available for the SAT input.
Depending on the LNC arrangement selected, vary-
ing switching signals are emitted when changing to
2
other channel positions (22 kHz, mini DiSEqC,
DiSEqC 1.0) in order to select the LNC required for
reception and its frequency range.
The oscillator frequency of the LNC used must be
entered. The number of possible oscillator frequen-
cies will depend on the LNC arrangement chosen.
The different variations in the 6 LNC arrangements
are shown on pages 14 and 15.
LNC oscillator frequencies ($)
The receiver is pre-programmed for the following
LNC oscillator frequencies:
A1
22 KHz off:
09 . 750 GHZ

Use the ] and | buttons to select the row you
want to change and enter the "new" value of the
oscillator frequency.
If you are using a number of LNCs, all the oscillator
frequencies will need to be checked and, if neces-
sary, "re-entered".
LNC voltage supply – to switch on/off
($ % )
The LNC voltage supply is switched on as a factory
setting. The receiver supplies power to the satellite
aerial.
If your receiver is connected together with other
satellite receivers to a joint aerial (a so-called single
cable solution in the master distribution), you will
need to switch off the LNC voltage supply
