Installation Menu51For ASTRA and EUTELSAT receiving systems, this is normally9.75 GHz (9,750 MHz) for the lower frequency range (low band) and10.6 GHz (10,600 MHz) for the upper frequency range (high band). Olderreceiving systems still use a 10 GHz oscillator frequency in the lowband range (which usually are not suitable for digital reception).The receiver generates the frequency to which it needs to adjust bysubtracting the oscillator frequency from the satellite transmissionfrequency saved for each programme. You only have to set theoscillator frequency used by your reception system. Before chancingthe LO frequency, you must therefore ascertain whether this is actuallynecessary.The oscillator frequencies listed in the text above are set in the factory.Changing the Oscillator FrequencyUse the  key to switch to the “LNB Confi guration Menu” on the right-hand side. The setting for “L.O. High” is highlighted in colour. You cannow use the number keys to enter a new frequency appropriate foryour system. This also applies to the “L.O. Low” setting. This is reachedusing the  keys.You can exit the menu by pressing  four times; this also confi rmsthe saving of the set value. If you make an incorrect setting, you will seethe following message: “Poor or no signal”.OperationThe factory setting is “On”. Select using the  keys.Under normal circumstances, the supply voltage should be turned on.For community antenna systems, you must ascertain whether thesupply voltage needs to be turned off.StandbyThe factory setting is “Off”. Select using the  keys.Under this option, you can turn the supply voltage for the LNB on or offin receiver standby mode. For single and community antenna systems,it can be turned off.If your receiver is connected to a multi-feed antenna, which is alignedwith the HOTBIRD satellites for example, you must change the receiversettings for the DiSEqC™(Digital Satellite Equipment Control) signal.This also applies to other satellites.Different control signals are required to select the satellite signals.However, the input frequency range for the receiver is in the range950 to 1250 MHz. The high frequencies are therefore converted into alower frequency using the oscillator frequency (LO frequency/L.O. = localoscillator, “LNB local oscillator”). Different oscillator frequencies areused for the conversion depending on the satellite frequency range andthe system type.
