Installation menuChanging the oscillator frequencyMove over to the right-hand side in the LNB configuration menu by pressing and the setting for LO High will be highlighted in colour. Using the number buttons,you can now enter a frequency matching your system. The same also applies forthe LO Low setting. Press the buttons to go to this setting.Press the 4 times to exit the menu. At the same time, the receiver will confirmthat the values have been saved.If a setting is incorrect, you will see the following message on the screenBad or no signalOperationFactory setting "ON".Normally, the supply voltage should always be switched on.For communal or party systems, you must check whether the supply voltage mustbe switched off!StandbyUnder this menu point the supply voltage for the LNB in receiver standby mode canbe switched on and off. It can be switched off for individual and communal sys-tems. The factory setting is "OFF".Receiving two satellitesIf your receiver is connected to a multifeed antenna which is also aligned with theHotBird satellites for instance, you will need to change the receiver settings for theDiSEqC signal. The same, of course, also applies to other satellites. (DiSEqC =Digital Satellite Equipment Control).Different control signals are required for the purpose of selecting the satellite sig-nals. To date, the LNB supply voltages 14/18 V and the 22 kHz signal (superim-posed on the LNB supply voltage) have been sufficient for signal selection in themajority of applications. With these four switching signals it is possible to switch be-tween horizontally and vertically polarised signals as well as between satellites(multifeed reception).However, additional control signals are now required for LNB activation and signalselection in view of the expansion of the frequency range to 12 GHz (high-bandrange) and for receiving more than two satellites.The "DiSEqC" control signal is responsible for this task. This signal represents aspecial modulation of the already existing 22 kHz signal.38
