11If you wish to operate your UFS 923 on a single-cable system, please refer to the con-nection example for single-cable systems (see "Technical Appendix", "Connectionexamples")This will only work when receiving one satellite, not in multifeed reception!(Multifeed reception: simultaneous receipt of signals from more than one satellite)To enable you to make use of all the reception and recording features of your Twin-DVR-HDTV Sat receiver,such as1. recording one program and at the same time viewing any other program or zapping through the channels,and2. recording two different programs at the same time,the two tuner inputs of the satellite receiver must each be supplied with a dedicated satellite signal from theantenna system/Sat outlet.The receiver tuner inputs are factory preset on the installation menu to work with two separate Sat antennaconnections.If you only have one antenna connection available, we recommend you interconnect the output of tuner 1and the input of tuner 2 using the loop-through cable supplied (see page 5).For this, in "First Installation" for tuner input 2 select"Looped through" (see "First Installation" chapter).Press the button to access the "Tuner Con-figuration" menu option, then select "Settings" and"First Installation". Go through step-by-step untilyou get to the tuner configuration.You can make the settings here, though a restriction on this is that with tuner 2 you can only receive theadditional channels of the plane currently set by tuner 1 (e.g. Horizontal High). Therefore, only the channelswhich can be selected are shown in the channel list.Information about antenna connection and loop-through modeConnection and start-up
