There is no communication with the television. The television is 15 years old. I don't think the remote control has any issues.

No synchronization was needed, I just inserted batteries and it worked immediately. It looks exactly the same as the original, just not as sturdy. However, for the price of 2.65 that I bought it, it is definitely worth it and more. Attention, it does not work for all F&U models.

The store service was excellent, but I believe that the product is not worth even a euro, you simply throw your money away. They replaced my remote control and sent me another one, but unfortunately it was exactly the same. It didn't work properly and didn't function at all

It worked with Telefunken. I don't know the model as we had to take the TV off the wall and I wasn't in the mood. But it worked immediately.
