I bought the multi-switch and could install it later, unfortunately. And he did not do it, of course. The LED lights up, but it's not a signal on to the Receiver. Upon request by e-mail to the seller you get helpful tips such as: Do you have the correct LNB or if you have connected the right cable to the right connector. No, I'm not too stupid to connect 4 cables. Have kuirzfristig bought a multiswitch TechniSat, connected and the system is running. Duration: 2 minutes. Thank you for the wonderful service provided by the seller and a defective device.
