Initial settings25Remote control handsetThe receiver contains command sets for Kathrein remote controls with both 24 and26 keys. The remote control included with the receiver has 26 keys and this is thepredefined command set on delivery. Therefore leave this setting unchanged as“26 keys“ (factory preset).Oscillator frequencyThe satellites radiate their programmes in a frequency range that satellite receiversare unable to process. In the receiving system (known as the LNB - Low NoiseBlock converter or LNC - Low Noise Converter) this frequency is converted into alower frequency that can be processed by satellite receivers.The satellite transmission frequencies lie in the following ranges:10700 ... 11700 MHz Low-band11700 ... 12750 MHz High-bandThe 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 theoscillator frequency (LO frequency). Various oscillator frequencies are used for theconversion 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 upperfrequency band (high-band). Older receiving systems still operate in the low-bandregion with 10 GHz oscillator frequency.The receiver calculates the frequency onto which it needs to tune by subtractingthe oscillator frequency from the satellite transmission frequency stored for eachprogramme.As a result, you can easily install the UFD 400 on other receiving systems withoutneeding to reprogramme every single programme slot.You only need to set up the particular oscillator frequencies that your receivingsystem 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 to12000 MHz directly via the numeric keys ... in 5-digit form, (e.g. 11700).• Save the settings with the key (press twice).All manuals and user guides at all-guides.com
