Installation Menu
You should not change the following settings without good reason as they represent factory settings or operational settings that are adapted to your receiving system.
New settings are only required when changes or expansions are made to the reception system.
The main menu consists of the following submenus:
Select the "Installation" menu with the menu button M, the oubuttons
in the main menu and O. If set, you must also enter the password. Select the
menu points with the oubuttons .
LNB configuration
The first submenu is the "LNB configuration". Press Oto open this menu.
Normally, you should not make any changes in this submenu. Before making any changes, however, you should make a note of the settings in the form provided at the end of this User's Guide.
Your receiver is set at the factory to the satellites of the ASTRA and HotBird systems.
The other basic settings are shown in the illustration opposite.
Oscillator frequency L.O.
Satellite receiver systems consist of the parabolic antenna (satellite dish) with the actual receiving system mounted in front of it (LNB – Low Noise Block Converter or LNC - Low Noise Converter) which converts the HF signals of the satellite to a lower frequency so it can be processed by a satellite receiver.
The satellite transmission frequencies are within the following ranges:
10.7…11.7 GHz | |
11.7…12.75 GHz | |
| (valid for ASTRA satellites at 19.2° E) |
The reception frequency of the receiver, however, is in the range from 950 to 2150 MHz. The high frequencies are therefore stepped down with the aid of the oscillator frequency (LO frequency / LO = Local Oscillator of the LNB) to a lower frequency. Various oscillator frequencies are used for this purpose depending on the satellite frequency range and the type of system.
For ASTRA and Eutelsat receiver systems, this frequency is normally 9.75 GHz (9750 MHz) for the lower frequency range
The receiver generates its required frequency by subtracting the oscillator frequency from the satellite transmission frequency stored for each channel. You only need to set the oscillator frequencies that your receiver system actually uses.
