Remote control handset
The receiver contains command sets for Kathrein remote controls with both 24 and
26 keys. The remote control included with the receiver has 26 keys and this is the
predefined command set on delivery. Therefore leave this setting unchanged as
“26 keys“ (factory preset).
Oscillator frequency
The satellites radiate their programmes in a frequency range that satellite receivers
are unable to process. In the receiving system (known as the

onverter) this frequency is converted into a
lower frequency that can be processed by satellite receivers.
The satellite transmission frequencies lie in the following ranges:
10700 ... 11700 MHz Low-band
11700 ... 12750 MHz High-band
The receiver‘s input frequency range, however, lies in the range: 920...2150 MHz.
Conversion of the higher frequencies into a lower frequency is achieved with the
oscillator frequency (LO frequency). Various oscillator frequencies are used for the
conversion according to the satellite frequency range and type of system.
For Astra and Eutelsat receiving systems, this is generally 9.75 GHz (9750 MHz)
for the lower frequency band (low-band) and 10.6 GHz (10600 MHz). for the upper
frequency band (high-band). Older receiving systems still operate in the low-band
region with 10 GHz oscillator frequency.
The receiver calculates the frequency onto which it needs to tune by subtracting
the oscillator frequency from the satellite transmission frequency stored for each
programme.
As a result, you can easily install the UFD 400 on other receiving systems without
needing to reprogramme every single programme slot.
You only need to set up the particular oscillator frequencies that your receiving
system uses.
On delivery the oscillator frequencies set up are those listed in the picture below.
Changing the oscillator frequency
•
Call the initial setup menu (see paragraph: “Calling the initial setup menu“).
•
Using the
keys move to menu entry “Oscillator menu . . .“.
•
Call up the “Oscillator selection“ submenu using the
keys.
•
Move to line in which you want to alter the oscillator frequency (LO 1... LO 4).
Various fixed pre-programmed LO frequencies can be selected with the
keys.
•
You can enter deviant oscillator frequencies in the range from 9000 MHz to
12000 MHz directly via the numeric keys
... in 5-digit form, (e.g. 11700).
•
Save the settings with the
key (press twice).
