The menu >LNB>Check will now be displayed, together with the DiSEqC setting
selected (e.g. A/A 1 ).
The following settings can be made:
LOF low band
LOF (local oscillator frequency) is the frequency used by the LNB to convert the frequency
received into the so-called 1st Intermediate Frequency, which can then be utilised by the
receiver. So-called universal LNBs utilise 2 LOFs in order to cover the whole frequency
range of 10.7 to 11.8 GHz (low band) and 11.7 to 12.75 GHz (high band). Using the numeric
key pad of your remote control, enter here the LOF frequency corresponding to the low band
of your LNB.
LOF high band
As above - using the numeric key pad of your remote control, enter here the LOF frequency
corresponding to the high band of your LNB.
Transition LOF low/high
Use the numeric key pad of your remote control to enter the frequency at which your LNB
switches from low band to high band.
Transponder Test
The following points of this menu should only be entered if you want to test a satellite signal
by means of a self-generated satellite (User 1 to 15).
Transponder frequency
Use the
numeric key pad
to enter a frequency at which digital programmes are broad-
cast.
Polarisation
Use the OK key to enter the appropriate polarisation plane ( h orizontal or v ertical) on which
the selected programme is broadcast.
Symbol rate
The symbol rate is an indication of the volume of data being transmitted per second. A typi-
cal rate might be 27000, indicating that 27000 symbols per second are being transmitted.
Use the
numeric key pad to enter the appropriate symbol rate.
FEC Rate
The FEC function adjusts error correction to the requirements of the selected transponder.
Use the OK key to enter the appropriate FEC. This can be
1/2
,
2/3
,
3/4
,
5/6
,
6/7
or
7/8
.
If the FEC rate is not known, use the Auto setting.
Signal
This line will indicate the signal strength, provided the details of the transponder have been
entered correctly.
