So pulled mains plug (it has a power switch not) and reconnected after a few minutes. Now you could not even turn on the remote control him. The LED flickered only to himself. Drag multiple restart attempts with a mains plug then led eventually to zwischentzeitliche success. But already a short time later the same game. "No signal" and no response to the remote control. Receiver defective - I thought - so kontaktet dealer. The sent me immediately a replacement receiver to exchange.
The new receiver also worked two full days without any problem. Then appeared the same function disorders such as the first receiver. Therefore must be something wrong in my opinion in principle on the device. I can not make purchase recommendation for this low-cost receivers.
